I am wondering if it is a bug or feature?
We've a WLC5520-HA-pair (software version 8.10.185.0), but I can only access the active WLC directly.
I know I can only access the standby-WLC through SSH, but I need to ssh from router, which has one direct connected interface in the WLC-management VLAN. But I can not connect via SSH from other network. It only works to active WLC.
I can ping the standby, but trying to use SSH just shows unanswered SYN-packets.
It seems, that standby WLC does not know the default-gw. But why can it reply to pings?
I am using the management ip-address, not the redundancy port. Redundancy ports are connected, but with 169.254. addresses.
Service port is not used.
Thanks.

When you say Management IP, you mean "redundant management interface IP"?
Once SSO is enabled, you can access the standby controller through a console connection or through SSH on the service port and on the redundant management interface.

You should be using the Service port.
Note that once in HA-SSO the routes must be configured on both WLCs separately. While logged into the active WLC:
"config route" for the active WLC and
"config redundancy peer-route" for the standby WLC.
"show route summary" and "show redundancy peer-route summary" to check the configured routes on each.
