Meraki switch dhcp failure on management vlan. VLAN 13 as the phone system server.
Meraki switch dhcp failure on management vlan Hi, I have a network that is currently running on a single VLAN which I am required to implement separate VLANS on. Happy this has resolved the Configuration Steps. If you change the management VLAN and the switch can no longer obtain a DHCP lease or reach Meraki Dashboard, the switch will revert to its previous management VLAN configuration. ; For switch networks: Switching > Configure > Layer 3 routing, and select the desired interface. Happy this has resolved the Basically, all the hosts in VLAN 2 are on this switch. Right now we have DHCP running on a Windows Domain controller and have configured DHCP relaying on all VLANs to point to the Windows DHCP server. VLAN 13 as the phone system server. Make sure the switch port that The upstream switch needs to be setup as a trunk port to the meraki. 20 and 10. Both devices grab DHCP addresses no problem. The SSID is configured with tagging for VLAN 3. I then build out vlans for Data, IOT and Wireless clients, pulling all my devices off of the Management vlan. Remotely rebooting the The APs cannot to Aruba switch on a trunked port in the default vlan allows vlan 31 and vlan 100(management). I told you that you knew the answer already. The WAP is a MR42, set with only one SSID, which is set to tag traffic as VLAN 10. If I turn on DHCP debugging for packets and events I can see the requests hit right after setting the native trunk vlan, however when it is set with no native trunk vlan I do not see any DHCP events. Say you make a new network, add a switch, and go to its details page. Meraki APs are able to get the IP from the mgmt subnet (via DHCP), however they are always complaining about "DHCP failure on management VLAN" i mean why the heck ? The document addresses troubleshooting steps for resolving DHCP conflicts on Meraki MX Expanding the more >> button will reveal information about the DHCP lease that was assigned: vlan 0 vap 0 subnet The MR45 devices are DHCP themselves do receive an IP from the same DHCP Server, in the same VLAN. And like recently said, make sure you have the right VLAN set on the Meraki switch config even if DHCP. ) Now the problem is my mer The trunk is setup as switchport trunk native vlan 181 (181 is the management VLAN). AP Tags for APs, setting VLAN ID to 3 . Hi. Meraki APs are able to get the IP from the mgmt subnet (via DHCP), however they are always complaining about "DHCP failure on management VLAN" i mean why the heck ? Solved: Hi all, I'm getting ready to install my first Meraki switch. If the switch needs a static IP configuration, make sure that IP is set correctly. This management IP has NOTHING to do with So thinking that this is the solution, I went ahead to change the static VLAN on the other switch that also had VLAN 10 to reflect this change. I have tried creating DHCP reservations for the switch, setting the IP statically and setting the native vlan to the management vlan. g. Happy this has resolved the I have a Meraki MS225 acting as an access switch having VLAN1 as Data and VLAN13 as Voice. I am just confused about the Native VLAN, Management VLAN and Uplink VLAN. " Can you clarify for me: are you saying run two physical If not, troubleshoot the connection between the switch and DHCP server, as well as the server itself. If your network does not allow the native VLAN or any of the default VLANs to DHCP or connect to the internet, you will need to manually assign a management VLAN. Set the AP to DHCP and leave the VLAN tag blank. We are running separate wireless and wired vlans on each floor. Assuming links from MX to Switch(es) are trunks allowing all VLANs change mgmt IP of switches to use the new mgmt VLAN. Remotely rebooting the firewall (MX84) and switch (MS250-48FP) did not fix anything. The management VLAN then has its Layer 3 interface on the upstream network, whether that’s an MX or something else (e. Alternately, you can specify the management VLAN under Configure > Switch settings . 3 Kudos Subscribe. DHCP config": VLAN 20 run dhcp server 1 day lease specifiy name server (added two nameservers on my local and remote network. I can see in the core switch some created VLANs with their respective subnets and I think they can be created from Switch > Configure > Routing and DHCP menu. DHCP is working for all VLANs expect for one wired vlan. Hi Guys, I am setting up a new Core Switch for our branch site. The AMI VLAN should not be the same as the Management VLAN configured on any of the switches (the LAN IP VLAN on the switch details page) or for the network (via Hi Rimccart, The NAK messages disappeared today after changing the dhcp port from trunk to access. 2(2)E4 . Now Hi Rimccart, The NAK messages disappeared today after changing the dhcp port from trunk to access. 0/24. Cisco port config: interface. vlan type status You can choose a management vlan at Configure > Switch Settings When it matches your switch configered management vlan the warning will i receiving the following in meraki SW - "t his device is using a DHCP IP address from VLAN113 instead of using config VLAN1" and i want the SW mgmt IP using the IP segment of vlan 113 without I plug two devices into the VLAN configured for the SVI as access ports. MS120 port should be in access when it is going to computer. Note vlan 1 is always open*** We do not have 1000 vlans in that network. When I installed the switches I left the management VLAN setting on the switch's config page blank and the switch adopted it as VLAN 1. and my Meraki AP works fine. Clients on our separated vlan aren't getting any IP via meraki. I have a customer with a access switch MS-220 and a core switch MS-350. Then set the switch port to native VLAN 11. I'm working on setting up a switch now and I keep getting this error, "This device is using a DHCP IP address from VLAN instead of using configured VLAN 1. In there you will find a VLAN field. If you leave that field empty, the switch will default to the management VLAN that is configured in the switch -> switch settings page. Its management, by default, is VLAN 1. So trunking to other switches isn't an issue. Happy this has resolved the This device is using a DHCP IP address from VLAN 0 instead of using configured VLAN 1 Solved Options. switchport trunk native vlan 3 switchport mode trunk Each port on the MS225 is tagged as access VLAN 10. . If the AP's configured management VLAN matches So thinking that this is the solution, I went ahead to change the static VLAN on the other switch that also had VLAN 10 to reflect this change. 13/22 Controversial. There is a scope in DHCP for each subnet that is associated with the VLAN. Happy this has resolved the I've whitelisted the DHCP servers on VLANs 10, 30, 40, 50, and 60 and this is what this switch sees for DHCP: What surprises me is what the VLAN 10, 30, 40, 50, and 60 Meraki switches are seeing in terms of DHCP - they are seeing DHCP traffic from other VLANs, and I'm not sure why this is. This will be a layer 2 access switch only. Hi community, I am completely new in Meraki technology. for example vlan 261 the dhcp is configured on the local switch where the ap is connected and vlan 111 on remote dhcp server . I have came up with some plans on the VLAN distribution Hi Rimccart, The NAK messages disappeared today after changing the dhcp port from trunk to access. However, after changing to the NATIVE VLAN and rebooting the switch, I now have this switch being issued with DHCP IP address and the static IP that was present is not any more. I also see UNTAGGED VLAN it says 0/5 DNS failures. Robin St. The site has an MX100, 3 MS120s, and a few MR44 access points, we have some on-prem servers and storage on this site (connected to a Cisco SG300 switch), DHCP is currently provided by an on-prem domain controller. Is vl100 in your switch uplink to your Coreswitch If that dhcp discover is at vlan 100 you have to check on the switchport and /or at the dhcp server if you see that Hello experts, i am new to meraki and vlan. The DHCP errors are only on VLAN 20. VLAN Settings: Ensure that the VLAN settings on both the AP and the switch are correct. Modifying the VLAN used for management traffic can be done via the local configuration page per switch or globally via the Meraki dashboard: Hi Rimccart, The NAK messages disappeared today after changing the dhcp port from trunk to access. 0/24 MX IP 172. 0/22. 10. no policy and no vpn. Or alternatively, have the Meraki on the LAN you wish to use. 21. Unless I misunderstand. Before the addition of the Meraki Management VLAN (1), the IPs were accessible. 0 (data) vlan 312 -> Now for the second aspect, VLANs that are only known on the MS, then the MX won't be present on those VLANs. ; Once there, the Client addressing setting will determine how DHCP messages are handled on i have few meraki APs connected to meraki switch . I have a PC Only plugged into this port. This management IP has NOTHING to do with All Meraki, no exceptions. Happy this has resolved the In there you will find a VLAN field. I have a Sophos XG as a firewall, we wanted to go for the MX So thinking that this is the solution, I went ahead to change the static VLAN on the other switch that also had VLAN 10 to reflect this change. Please can someone explain to me the function of an MS switch's management interface VLAN field (found within a switch's LAN IP settings pane): Is it in reference only to switch-to-dashboard traffic (information the switch needs to communicate to dashboard and vice versa) or to management traffic in the sense of STP/RSTP, CDP etc I also tried just setting the management IP to use DHCP in a vlan on our internal network but I get the same message. I got So thinking that this is the solution, I went ahead to change the static VLAN on the other switch that also had VLAN 10 to reflect this change. ) One for Management with the rest of Meraki devices? (Switches & AP`s) Second VLAN - for users. Are you changing to a static IP in the same subnet that it currently is in with DHCP? Also, make sure you're not double tagging VLANs. Meraki APs are able to get the IP from the mgmt subnet (via DHCP), however they are always complaining about "DHCP failure on management VLAN" i mean why the heck ? Hey, My DHCP Server has a reserved range of 172. You have to set the SSID to use NAT Mode : Meraki DHCP if you want it to hand out different set. Meraki APs are able to get the IP from the mgmt subnet (via DHCP), however they are always complaining about "DHCP failure on management VLAN" i mean why the heck ? Our primary VLAN is VLAN10 and I have created a new VLAN8 to move clients over to. Just wait until you plug in an AP with no network access, When I add a Meraki switch to my network it routinely pulls an IP address from the wrong VLAN. The VLAN 182 is configured on my switch only. I bought a Meraki MS-120 to replace the 2960. So thinking that this is the solution, I went ahead to change the static VLAN on the other switch that also had VLAN 10 to reflect this change. Personally, I assign all Meraki devices My issue is this new core MS-250 switch has DHCP enabled for my new MGMT vlan 87, and a downstream Meraki switch will grab an IP as it should, and I can see it in the dashboard. Clair | Principal A 'button' to clear DHCP Leases from dashboard is certainly a feature request at this time point in time as others have commented. 2nd. Press the button to add an interface, and select the MS120 as the switch you are adding an interface on. The DHCP pool for VLAN 20 is 85% free, so I do not think that is the issue, If you want the AP to be on VLAN 11 and the switch port to use VLAN 11 as it's native (or untagged) VLAN, here's what you should try. I would only allow VLAN 20, 30 and 40 to pass the trunk between the i have few meraki APs connected to meraki switch . The above image represents a native VLAN configuration where management traffic flows untagged across the switch port links normally. I gave it 10 minutes and came back and was successfully migrated off of vlan 1 completely. 1 Vlan 20. The AP should be tagged on the AP-MGMT VLAN, and the switchport should be configured to allow the necessary VLANs. The APs are connected to the switch via a trunked port, which is set to Native VLAN 1, but all VLANs are allowed. All devices are assigned to the default profile unless explicitly assigned to a non-default profile. We have 3 separate vlans at the site (guest,corp,mgmt), i'm trunking all these 3 VLANS towards the AP, mgmt vlan is set as native. The first thing I would do is setup a new VLAN under "Addressing & VLANs" and enable DHCP. On each of the VLANs is a DHCP server, which is part of the MX68, not external to it. The default profile will always be the source Anyway it looks like a way round this would be to have a second link between the catalyst and the MS, with the native vlan set to 25 at both ends, then change the management vlan to 25, it should then start communicating to the Meraki cloud through this second link and we can disconnect the original link. The other VLANS have no issues. This has been working as it should. One of the VLANs on the MX68 is for the Guest network (VLAN 3). If you change the management VLAN setting prior to adding the switch though, it'll appear with its management on the VLAN you configured. SSID Public uses meraki dhcp ; SSID GP uses Pre-shared key, local LAN but no vlan tagging (untagged). SSID in Bridge mode, with VLAN Tagging. I'm able to claimed the switch(MS390-48UX2) but when i tries to add the switch to network i get following message ***This switch is limited to 1000 vlans, Please check your vlan related configurations on all ports, and static and management vlans on the switch and network. 11x authentication and uses vlan tagging. When there is an IP addressing issue, a Meraki Go device will attempt to find another working IP address via DHCP on other networks (or VLANs). What I can't see is this core MS-250 switch. I am seeing errors in the VLAN request status on the LAN tab of the access point. To make that happen you need to tell the MS to forward (Relay DHCP to another server) all DHCP requests towards the MS in Switch > Configure > Layer 3 routing. Then bounce the port. The MS125 is connected to the MX with a single ethernet port set to trunk with native VLAN set to 666. We have three SSIDs: SSID Private requires 802. Happy this has resolved the The AMI IP address can be configured per switch. x). View solution in original post. You’ll also need to configure a new DHCP scope for VLAN 30 and, and if the DHCP server isn’t actually on VLAN 30, then configure a DHCP relay/forwarder on the Layer 3 interface for the VLAN. I plugged my laptop directly into Port 4 and I do get an IP address (on the native VLAN 192. Step 1: Security & SDWAN>Address & VLAN> Add VLAN Step 2: Now go to Security & SDWAN->Address & VLAN-> Per port VLAN setting and it should be trunk depend upon Native vlan you have configured like 1 or any The APs cannot to Aruba switch on a trunked port in the default vlan allows vlan 31 and vlan 100(management). This allows the switch to reach the internet via a trunk port. All switches and APs are set to management VLAN 2 and are pulling DHCP addresses from the MX. Hello, I am experiencing a problem that has been existing for a while so far, Well, the issue is that 1~10% of the endpoints when attempt to connect to the SSID, it fails obtain IP address, and it shows on Meraki dashboard (DHCP server did not response), while DHCP server is responding and able to provide IPs for any other end point around and attempts to connect. native vlan is 1 and is working fine. The DHCP server resides on another subnet and we have activate the relay server on the DHCP on the meraki dashboard. Old. APs' ip address is on management vlan network. And welcome to the Meraki world. This management IP has NOTHING to do with Now for the second aspect, VLANs that are only known on the MS, then the MX won't be present on those VLANs. All lan ip's set to DHCP and left the vlan box empty. Mobile Device Management; Smart Cameras; Sensors; Platform. However, there is a way to clear the DHCP Leases on a VLAN without having to reboot the appliance by following these steps: - Create a DHCP Reservation on the VLAN that blocks out the entire DHCP range Most common issues are ports not set as trunks, not allowing required VLANs, mismatched native VLANs. Could it be, anyone ever heard of, that when. The addressing on the switch is set to use DHCP and my DHCP server has a reservation to give it the correct address (which it I have the standard vLan1 as default and vlan20 configured to be my guest wifi LAN . Well, it doesn't work, no DHCP messages are seen at the DHCP server sourced from the switch. We have three Could it be, anyone ever heard of, that when on the first interface, if the DHCP pool is exhausted there, an MX100 starts giving out addresses from the DHCP pool from the other Well, the issue is that 1~10% of the endpoints when attempt to connect to the SSID, it fails obtain IP address, and it shows on Meraki dashboard (DHCP server did not When I introduce the switch, and plug the WAP561 into port 4, I am not able to get a DHCP address. There is routing between the VLAN I am on and VLAN 2 yet I cannot PING the new switch, VLAN 2 > WAN is open but switch is not connecting to the dashboard, it reverts to getting an IP on VLAN 1 even though I have set the IP manually in the dashboard and there is also a DHCP server on VLAN 2 . If you apply a new management IP configuration and the switches fail to talk to the Meraki cloud the switches will try and revert back to what is was before you made the change. Allowed VLANs: All . i have few meraki APs connected to meraki switch . I'm not sure why the switch even tried to auto discover IPv6 when it has IPv4 connectivity. Happy this has resolved the We are running separate wireless and wired vlans on each floor. 95. I have globally set management to vlan 87, and on each switch told it to use DHCP in vlan 87. What I am trying to grasp is the management network. You asked me once, what was in Room 101. a Cisco router). By default all trunk ports will forward all VLANs, but you can restrict (prune) this to just It's all about new deployments. Dunecat • If it's DHCP failures, then look at the DHCP server, and the relevant VLAN trunks The meraki built-in DHCP you may want to review the logs as it may indicate causes Today the configuration on the trunk port between the switches is: Management VLAN: 153. 1 - 30 and from within it the static IP Address is used for the switches and Access Points. It can still be DHCP server for those VLANs though. If I set the native trunk vlan to 11 for the 2 access point interfaces it works fine and the access points make DHCP requests without issue. Here is the view from a switch on the VLAN 30 network: Management VLAN. Since the MS120 is an L2 switch these interfaces are limited in their operation. 16. Meaning if you have an AP connected to a switchport which is something like trunk, native 1, allow all VLANs. All you have to do is assign an access port to a VLAN. boot option disabled. Both devices can ping the interface. DHCP. Make sure the switch port that connects There’s corporate wifi which takes IPs from a DHCP scope on the firewall, and guest which uses meraki DHCP. Happy this has resolved the Hi Rimccart, The NAK messages disappeared today after changing the dhcp port from trunk to access. 1. They cannot be used for general purpose routing or full fledge DHCP servers -- only DHCP relay and IGMP querier configurations are a separate management VLAN; all VLANs explicitly declared; explicit declaration of VLANs permitted on trunks; use of a blackhole VLAN where configuration insists upon an entry; Personally, I suggest using 101 as the black hole . I see for VLAN 10 5/5 DHCP failures. Make sure the switch's management VLAN is configured correctly, or So thinking that this is the solution, I went ahead to change the static VLAN on the other switch that also had VLAN 10 to reflect this change. That gave the Meraki an IP address in the Data VLAN Switch --> Routing & DHCP . They cannot be used for general purpose routing or full fledge DHCP servers -- only DHCP relay and IGMP querier configurations are Alternately, you can specify the management VLAN under Configure > Switch settings. This management IP has NOTHING to do with Hi Rimccart, The NAK messages disappeared today after changing the dhcp port from trunk to access. By default, Meraki switches are configured to use VLAN 1 for untagged and management traffic and all switch interfaces are configured as trunk native VLAN 1. I got New Switch Management VLAN = VLAN 2 . MS120 is L2 switch so you have to define the VLAN in MX65 by going into . Currently company is running on a normal LAN with static IP on the server and switches etc Recently i brought in a MX250 and MS350-24P to buff up the network. I have separate DHCP Servers on each VLAN, VLAN1 as a windows DHCP Server. The trunk is setup as switchport trunk native vlan 181 (181 is the management VLAN). Assumes it's allowed on the ports down to APs as well as the ports between the MX and Switch(es). Basically the idea is start from the edge moving inward and having a safety net of DHCP in case anything go sideways. if I configure the switch to have a management vlan of 2009 DHCP it fails and the switch reverts to getting DHCP ID from VLAN 1. 112. Its easy to configure on meraki dashboard and dhcp is enabled for your vlans. The vlan 100 is the mgmt ap and the only vlan 111 no works the dhcp. The rest of my network is Cisco. 13. The DHCP pool for VLAN 20 is 85% free, so I do not think that is the issue, My both switch have an IP in the VLAN 1 (DHCP), Uplink on Sw01 Port10. On each VLAN interface a DHCP pool is active. " I have DHCP The DHCP errors are only on VLAN 20. I want to change this IP with a static IP on VLAN 182. To configure, navigate to For security appliance networks: Security & SD-WAN > Configure > DHCP, and refer to the section for the desired VLAN/subnet. 172. Good morning everyone. Apologies for the newbie questions. I know each switch in the stack will need an IP for manament but how will this work at the core? If my management subnet is 10. In an attempt to set up VLAN's for an existing network that I built-it currently operates on a flat private Hi Rimccart, The NAK messages disappeared today after changing the dhcp port from trunk to access. Alternately, you can specify the management VLAN under Configure > Switch settings. 168. The DHCP settings in the MX are almost the same between all the VLANS. Hi @SAM-Al. We have a switch stack comprised of three MS250-48 switches. mr45 - DNS and DHCP failure I have in my network 6 mr33 and 1 mr45. I got Hi Rimccart, The NAK messages disappeared today after changing the dhcp port from trunk to access. One device has been given a dhcp address some time ago, and continues to renew it's lease, but subsequent attempts are failing, with no IP address being assigned. You can either allow specific VLANs or all VLANs. Dashboard & Administration; Full-Stack & Network-Wide; Just to sort out a problem "behind" Meraki AP. Happy this has resolved the VLAN Settings: Ensure that the VLAN settings on both the AP and the switch are correct. Happy this has resolved the Hello, Meraki Community, I have most recently jumped into learning about VLANs via articles and YouTube videos. As soon as I enable DHCP relay on the MX67 again, for the same VLAN, the messages start appearing, so I would expect the switch to do the same. Switch --> Routing & DHCP . So depending on your upstream trunk configuration you can have success or failure to get the switch online to the meraki dashboard. @ShadiusFirst create the new VLAN interface on the MX and make sure it has a DHCP server assigned to it. The APs cannot to Aruba switch on a trunked port in the default vlan allows vlan 31 and vlan 100(management). 22. I am preparing to move from inter-VLAN routing on the MX to L3 routing on the switch stack. All forum My suggestions are based on documentation of Meraki best practices and day-to-day experience Alternately, you can specify the management VLAN under Configure > Switch settings. I got Today the configuration on the trunk port between the switches is: Management VLAN: 153. Everyone knows it. 21 for these switches. I'd expect to see a forwarded DHCP request with the GiAddr set, but nothing shows up. Now it _seems_ that something strange is happening. The MX running the Meraki network has its WAN port on a native LAN that is connected to the LAN port of the external facing security Put switches and APs on the Management VLAN, which most definitely should not be VLAN They get their IP address from the Management VLAN DHCP server on the MX. When I add a Meraki switch to my network it routinely pulls an IP address from the wrong VLAN. I would then change the management VLAN under Switch Settings to the new VLAN ID, then reboot the switch so that it picks up a new IP address on the new VLAN (and/or manually set the IP address and VLAN on the switch's configuration page. Looking at the Health of the AP's we are getting 100% DHCP failures on the guest SSID and 40% on the corporate SSID. Hi Rimccart, The NAK messages disappeared today after changing the dhcp port from trunk to access. If your meraki has NOT gotten the configuration that declares the mgmt vlan you have to use the native vlan on the upstream switch to get it to obtain an address in the correct network (by default meraki uses VLAN 1). At a cursory glance the rest of your configs look okay. There shouldn’t be any problems leaving it as it is. I am not sure what my issue could be. This is not desired. The DHCP relay server must be reachable in The DHCP errors are only on VLAN 20. The management internet is connected to MS-125-1, and the trunk I want to modify is the uplink trunk for management between MS-125-2 and MS-125-1. be 10. It's a MS-350. In the cabinet where the switches and AP are directly connected to the firewall (stack 1) everything works as intended, but in stack 2, the AP seems unable to talk with the firewall to get DHCP, it fails every time. The policys are all right and verified that they allow traffic in and out the network which the dhcp server Key Profile Management Details (please do not skip this section). Just makes it fewer clicks is all really. When the switch port on Switch 2 is misconfigured to VLAN 20, the management traffic will continue to flow between Switch 1 and 2, but any traffic returning to Switch 1 is treated as So thinking that this is the solution, I went ahead to change the static VLAN on the other switch that also had VLAN 10 to reflect this change. Reply. I have finished connecting the switch to DHCP, updated the firmware and stacked it. Only vlan 111 with remote dhcp failed. To add or remove a VLAN name or group, you do so under the default profile, which will then propagate the added/removed profile to the non-default profiles. One of the 3 devices in VLAN 2 has IPv6 connectivity and the switch AutoConfiged and is trying to talk to Meraki on that VLAN. But the dashboard tool to ping from the interface to the device fails as well as the device to device ping attempt. The addressing on the switch is set to use DHCP and my DHCP server has a reservation to give it the correct address (which it The DHCP errors are only on VLAN 20. In your case, I would recommend configuring your aggregation switches' management interfaces in the transit VLAN (so that they can still function if anything happens downstream), Hi there . All MR42 do tag Solved: Hi all, A client of mine has an MX100 firewall, on which 2 VLANs are configured on the inside. The MX is connected to the ISPs router with a single ethernet connection with a DHCP private address and no VLAN set. The traffic shouldn't even be leaving the switch? i have few meraki APs connected to meraki switch . 0. All of them are setup the same, but mr 45 has issue with connecting vlans. If your meraki has NOT gotten the configuration that declares the mgmt vlan you have to use the native vlan on the upstream switch to get it to obtain an address in the correct network (by The document addresses troubleshooting steps for resolving DHCP conflicts on Meraki MX devices, highlighting common issues like IP address overlap, lease exhaustion, and rogue DHCP servers, providing When I add a Meraki switch to my network it routinely pulls an IP address from the wrong VLAN. Do the VLANs exist on both switches? (show vlan), configuring a L3 interface doesn't automatically add the underlying L2 VLAN in the switch database. The other vlans works fine. The image below represents a VLAN mismatch. I have 2 SSID : bridge mode & NAT (DHCP Meraki) Then we implement VLAN in our network, now Meraki AP port in switch already change to VLAN Client segment with different IP (10. They cannot be used for general purpose routing or full fledge DHCP servers -- only DHCP relay and IGMP querier configurations are When I add a Meraki switch to my network it routinely pulls an IP address from the wrong VLAN. Sometimes I get DHCP assigned IP from the voice vlan on the PC on startup. The alert is caused when: A VLAN tag is set for DHCP, and DHCP IP assignment fails Since the AP is configured to use VLAN11, the port it plugs into on the switch should be a trunk port, and it can use a native VLAN of 1 (make sure the switch is not using a native vlan of 11). The DHCP pool for VLAN 20 is 85% free, so I do not think that is the issue, My mistake, you are correct the MS120 is L2 only but has the interface added for DHCP relay. Q&A. DHCP Server: Ensure that the DHCP server on the AP-MGMT VLAN is not set to respond to client requests. This management IP has NOTHING to do with Yes, the vlan is configured to the port's. Switch: Cisco C2960XR Ver: 15. I think the dhcp server was responding to numerous dhcp requests from different vlans while on trunk hence generating the NAK messages. The MX running the Meraki network has its WAN port on a native LAN that is connected to the LAN port of the external facing security Put switches and APs on the Management VLAN, which most definitely should not The trunk is setup as switchport trunk native vlan 181 (181 is the management VLAN). Happy this has resolved the If you change the management VLAN and the switch can no longer obtain a DHCP lease or reach Meraki Dashboard, the switch will revert to its previous management VLAN configuration. The 3850 fails as well because it Meraki would only hand out local LAN (allowing your domain DHCP to offer IPs) if you had Bridge Mode or Layer 3 Roaming set under the SSID you were connecting too. Switch says it sees only 1 DHCP server. That way, if it runs into problems with its static config, and leave things as DHCP on that VLAN for switch management. As has been said though, it’s recommended to keep management traffic on its own VLAN. Happy this has resolved the When I add a Meraki switch to my network it routinely pulls an IP address from the wrong VLAN. Since the AP is configured to use VLAN11, the port it plugs into on the switch should be a trunk port, and it can use a native VLAN of 1 (make sure the switch is not using a native vlan of 11). It is recommended to have a dedicated VLAN for management traffic, although not always required, per our KB article for Understanding and Configuring Management VLANs. Also make sure you enabled DHCP on the MX for data and voice VLANs and that you allow the MX on the switch for DHCP (Switch -> DHCP but I keep running into a few problems. The management vlan is configured in the dashboard and I connect the switch to a trunk port on a Cisco 9500. 20. I had configured the port that connect the dhcp server to trunk with native vlan 1. I would only allow VLAN 20, 30 and 40 to pass the trunk between the an ip helper-address to manage dhcp requests out of your vlan. Went in the MS settings and overrode the management vlan to 10. make sure that the switch has access to DHCP via some vlan. So I used those settings : An IP on the VLAN By default, the switch will try to contact Meraki Dashboard on the untagged (native) VLAN.
