WLC 2006 redundancy on HSRP switch

My current setup is 2 units L3 switches running HSRP. The port 1 of WLC is connected to one of the L3-A switch.

Is it possible for me to connect port 2 of my WLC to L3-B switch(same SSID)so that in case of L3-A switch down, my WLC and wireless AP still functional?

Re: WLC 2006 redundancy on HSRP switch


No - I've just set up one of these 2006 controllers and there isn't any way to connect to multiple switches in a fault tolerant way or aggregate links for performance.

You can tie a VLAN interface to a particular physical port, but this just ensures 100Mb of BW is dedicated to that VLAN...

The larger 4100 and 4400 controllers support STP and in-built link failover, but the 2006 doesn't seem to.

Re: WLC 2006 redundancy on HSRP switch

We're running such a setup with 8 4402. It takes aprox 45 seconds for the aps to failover from one port to the other. Unfortunately HSRP is not enough. Be sure to configure a separate ap manager interface on each port.

TAC has provided us with some infos optimizing the setup and the BU is working on a setup making the failover faster.

Currently we see that connections from WLAN users using VPN tunnels will break during failover as timeouts are too long. EAP-TTLS connections will usually survive.
