9800 WLC - HA

[besart-rexhepi]

Hi

I have two WLC 9800 in HA.

Active WLC is in server room A Standby WLC is in server room B.

RP is connected with direct fiber.

Link ports are connected to 9500 switch (one in server room A and one in server room B) between the switches I have a trunk that allows all VLANs.

In the switches I have "Port-Channel x Mode On" but only one link from WLC (for now).

When I do a failover the standby wlc does not take over. I am wondering if it is "Channel-group X mode On" that causes the standby wlc not to take over becauce the port do not get up?

Shouldn't I have "Channel-Group x mode Active"?

Both WLC have a path to the Default Gateway.

If the 9500 are not in a VSS then the WLC cannot be in an etherchannel across two "different" 9500 switches.

I know 

I have two Server Rooms

Server room A
9500 switch HSRP Active + Active WLC

Server room B
9500 switch HSRP standby + Standby WLC


The two 9500 are connected with fiber (Trunk) from Room A to Room B

The WLCs are connected to its switch with 2 links (2x 10GB) and RP via direct fiber between rooms.

Everything seems to work now after I found a broken SFP in the Standby WLC

maybe not the right design?

Yes, that is a good design 🙂 glad you worked it out.
