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:
- Connectivity (through PRTG) with WGB is flapping so services behind were affected.
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:
- Enable Multicast, previously the final customer disable this feature.
- Vlans were pruned to the WLC to only what it needs
- Disable passive client (two weeks ago was enabled), in this point the services is more stable WGB is response from network and services is no affected, so we understand with the passive client is enabled the proxy ARP feature is disabled, so we make to captures in Switch IE300 for another issue one week ago, and we saw too many ARP broadcast from Gateway to all WGB and clients connected to WGB, so our doubts is this symptom is in relation with the message on WCS, version on 1300.
Any comment or action is welcome.
Thanks a lot!
