Dear all,
We have issues with our mesh network, we have a 2 WLC 5508 ver7.0.220.0 (connected to 3560 with LAG) 16 APs1524, 60 Bridges 1300 ver12.3.8-JA2 configured like Workgroup bridge (mobile stations), 20 Switches IE3000 connected to WGB and services connected to SW IE3000.
Network is working relatively fine, links in our backhaul is OK SNR lower is 21 and max hops on MAP is 2, we have just one wlan configured, with passive client feature enabled, multicast feature is also enabled, in two times when one MAP is moved to another position (is mining environment) network present instability we have following symptoms:
We understand if moved a MAP into Mesh probably network convergence, but when network is stable the symptom are maintained, the most strange is from the network we don’t have connectivity to 1300 however connectivity to Switch is OK, in fact we can connect to SWITCH and from it we can connect to 1300 when we are inside Bridge everything interfaces are up including radios, logs show some deauthenticate, but we have configuration without authentication just for now. In WCS we have a alarm CPU Receive Multicast Queue is full on Controller in the time that issue is arise. We make to following actions:
Any comment or action is welcome.
Thanks a lot!

What kind of clients are behind the IE3000's? Are they passive?
The proper way to work with the passive clients is putting their MAC address in the Mac Filtering in the WLC and enabling the "passive client" in the WLAN.
Then you enable L2 bridge forwarding on the 1300 with the "bridge 1 addressxxxx.xxxx.xxxx forward FastEthernet0" command.
Then you add a static arp entry in the L3 switch that the SVI resides on.
When you don't have connectivity to 1300. Keep a ping going to it and then try to ping it from your IE3000. If it starts pinging from you computer immediately after that - it sounds like you have an ARP issue.
Is it possible to post the configs of the IE3000's and 1300's?
