Meraki wireless dhcp relay I'm currently using my MX67 for DHCP relay but I thought I'd test it out on the MS120 to see what happened. I have an MS250 stack of two switches running 11. Tried it in bridge mode I have a set up a wireless network for one of our remote site where clients are meant to obtain an IP address from a DHCP server located at Head I am not a Cisco Meraki employee. If the dhcp lease is around 75% expired the camera will do a dhcp renew ( r-a ) . AP's don't receive an IP address from DHCP server (Infoblox), even though some devices on the same network segment do. 32? We recently updated our MS350 stack from MS12. Set MS390 as DHCP server as a workaround and AP's receive IP, then back to relay seems to fix the issue but issue returns after awhile Greetings I am configuring Meraki MX100 to my network (to replace cisco asa 5525-x), this will be sitting in my network rack at HQ. The settings for this can be found in the normal DHCP Settings Page. Wi-Fi clients joining the same VLAN from Cisco AP devices do not have the same issue. I dont now if dhcp relay works on other vendors with nat/pat but meraki does not support it. 60% of the IP addresses in range of DHCP Scope are available. The switch stack is configured with several vlans and vlan interfaces all setup to relay dhcp to offsite dhcp servers. what the MX is going to do which is NAT on the outbound. WAN1 Just to add to what @PhilipDAth rightly pointed out, this doesn't mean MS120 won't work in environments where you need clients relayed to an off-subnet DHCP server but, with an MS120, you are reliant on the BOOTP messages being forwarded at Layer-2, rather than relayed at Layer-3 (MS120 doesn't do layer-3 routing). Configuring DHCP Options. " Connectivity is clearly established and the route exists, so why can I not enable DHCP relay? We are fairly new to Meraki (Wireless - Mostly MR46). Both of these settings can be verified by navigating to If the DHCP server is not in the same subnet / VLAN than the client, then you need a DHCP Relay to receive that broadcast and forward it to the DHCP Server in unicast. The meraki switches have a But when I connect a phone to this SSID, it doesn't get an IP back. That subnet is on your asa so Its routed using the default route on the mx nat interface. Outbound traffic will be natted to the WAN int IP. I have a VLAN 3 which my DHCP sits on. If you want to forward DHCP requests for a configured subnet or VLAN to another DHCP server rather than serving DHCP on the MX, you can do so by choosing the Relay DHCP to another server option for Client addressing and entering the IP address of the DHCP server you wish to forward requests to. Devices are DHCP. 31 code. Moving form Cisco unified wireless.

Clients on our separated vlan aren't getting any IP via meraki. The DHCP relay server must be reachable in We had two dhcp servers on active active mode initially enabled for the affected SSID. 20. Firmware update did not also help. According to the Routing & DHCP page these switches should support DHCP relay (but no other L3 functions). When I set VLAN 100 to relay DHCP to 192. We are experiencing a DHCP issue with one of our vlans. Both the request and ack will be unicast. but Mandatory DHCP requires a DHCP transaction per roaming , which is not part of the IEEE standards so some devices do not have to support it. 100. The retail store's network is coming in direct and the VLAN terminates on the ASA. 17 to MS14. Not inbound to the wireless clients. From packet capture on the ports dhcp servers, ACK messages were only being received from on server. " To leverage a DHCP relay option, the MX appliance must be in "Routed" mode and also you must have VLANs enabled. Hi All, We are running MR42 with Meraki Switches and using DHCP as a relay to a Windows Server - we are seeing a high number of these DHCP errors below - mostly the connectivity is ok but some reports of clients dropping out. For Client addressing, We need to configure New Meraki APs so that they can have same SSIDs and IP addresses from the DHCP server in parallel to the existing network. Auto If that dhcp discover is at vlan 100 you have to check on the switchport and /or at the dhcp server if Wireless - configure - Firewall & traffic shaping . DHCP Server is Windows Server 2008 R2, no errors logged in the event log from the DHCP-Server.

But only is working DHCP relay en highest VLAN (163), in dhcp relay vlan (100) no work. 1. So, in this scenario DHCP relay is not possible? The route exists (through the primary "WAN" link) but it is not in the route table so DHCP relay . The Switching > Monitor > DHCP Servers & ARP page displays information about any DHCPv4 and DHCPv6 Servers and IPv6 Router Advertisements seen by Meraki Switches on the LAN. We are fairly new to Meraki (Wireless - Mostly MR46). We have a retail store that is directly connected to our network via fiber, thus we have the AutoVPN disabled (as it is not needed). Set MS390 as DHCP server as a workaround and AP's receive IP, then back to relay seems to fix the issue but issue returns after awhile We are fairly new to Meraki (Wireless - Mostly MR46). The meraki switches have a L2 trunk PO to my Cisco core. The port that connects to the AP should be configured as a trunk port and you should allow VLAN 1, VLAN 2, and whatever VLAN your AP is using for management (if it’s not VLAN 1). Note: The DHCP server configured must be in a subnet configured on the MX, including directly-connected VLANs, static routes, and subnets I have a few MS120 switches in use. We are looking at using Meraki NAT/DHCP. I have a DHCP relay won't work and I still can't get the APs to talk to the NPS on the other side of the tunnel.

DHCP relay is also configured on the SVI for Vlan 10. I noticed the following restriction when configuring the dhcp relay server on a Vlan configured on the MX "IP address of DHCP server to relay to. The IP address must be in a subnet connected to this Meraki network or to a Meraki Overview. We had two dhcp servers on active active mode initially enabled for the affected SSID. It is hard to pin down. The IP address must be in a subnet connected to this Meraki network or to a Meraki So within the hub and spoke environment, if the Data vlan is set to run its own DHCP server, with its own vlan and ip range, even though there is a vpn aspect involved, their either isnt any DHCP requests being sent or received to the hub mx over that VPN unless you enable the relay, is that right? We had two dhcp servers on active active mode initially enabled for the affected SSID. 10) and one for VLAN 40 (0/0/1.
