Cisco 3504 WLC HA SSO

[a.burlaos]

Hi,

Does anyone tested the Cisco 3504 WLC HA SSO? I've tested the setup in a standalone network were the two WLC is connected to a switch and HA is working fine but when the WLC is connected to actual setup i've encountered peer communication down error between two WLC's.

WLC is connected to a separate DC. Please attached diagram for reference.

Thank you,

Arvie

When the WLCs are not directly connected there are requirements around connecting the RP port

For the redundancy port:

Requirements for L2 connection: RTT Latency: < 80 ms; Bandwidth: > 60 Mbps; MTU: 1500

If you are not meeting these requirements you will not get SSO to work
