Cisco virtual WLC C9800-CL going to recovery-mode

[icarimo]

Hello,

I am configuring 2 C9800-CL WLCs.

I am trying to configure HA with RMI + RP.

However, I set all required configuration, however WLC #1 goes to recovery-mode and after some reboot it the other goes WLC #2 goes to recovery-mode and WLC #1 normal mode.

And when the WLC is in recovery-mode  the MGMT IP is unreachale, and something strange has happen the MGMT IP of my VLAN has changed to the RMI IP, and I am only able to acess via this IP.

WLC in recovery-mode

WLC in normal state:

"Active-Recovery is when the RP goes down. Active-Recovery does not have its internal state in
sync with the Active. Active-Recovery will reload when the RP link comes up so that it can come
up as Standby with bulk sync."

Your problem seems to be related to connectivity to me. Do you manage the vCenter where this WLC is installed? or the Cloud if that is the case.

Thank you Flavio
So it seems that some issue with L2 configuration of the VLAN right?
I dont manage the VMware, also I dont manage the switches, I believe that the issue is related to the VLAN configurations.

I will double check.


Just to confirm, both WLCs can reach the default gateway, and since there is no L2 (RP) communication, this could explain the recovery-mode status?

 Exactly. If the issue were the communication with the gateway you would probably see the "Standby-Recovery" state instead the "Active-Recovery" as you are seeing now.

This means communication problem on the RP port.

It issue of RPI sure.

Reachable of GW depend on RMI not RPI.

I think it issue of vnc you assign for RPI.
