WLC SSO - firmware version 8.0.110.0

Hi All,

 

has anybody made working SSO between two WLCs on this fw version?

 

I set it according to many guides available on the on the Internet, SSO enabled:

 

(czc-hat-mohel-3) >show redundancy summary
            Redundancy Mode = SSO ENABLED
                Local State = ACTIVE
                 Peer State = STANDBY HOT
                       Unit = Primary
                    Unit ID = A4:93:4C:B0:D0:E0
           Redundancy State = SSO
               Mobility MAC = A4:93:4C:B0:D0:E0
Management Gateway Failover = DISABLED
            BulkSync Status = Complete
Average Redundancy Peer Reachability Latency = 426 Micro Seconds

 

(czc-hat-mohel-3-Standby) >show redundancy summary
            Redundancy Mode = SSO ENABLED
                Local State = STANDBY HOT
                 Peer State = ACTIVE
                       Unit = Secondary (Inherited AP License Count = 12)
                    Unit ID = 7C:0E:CE:63:A8:40
           Redundancy State = SSO
               Mobility MAC = A4:93:4C:B0:D0:E0
Management Gateway Failover = DISABLED
Average Redundancy Peer Reachability Latency = 419 Micro Seconds

 

But when I issue a command "redundancy force-switchover" it simply does not work.

 

Ping reply to management interface times out. Primary unit reboots and StandBy unit starts to respond on the management interface in about 30 - 40 seconds later on.

 

I suppose that it is not supposed to work like that.

 

Thanks!

Depends on your LAN network.   This sounds like an ARP issue if standby WLC starts responding after 30-40 seconds.

Don't think so, even from logs the role change occures after some time, not immediately after reboot. Tomorrow I will past some logs.

The fastest change occures, when default gateway check is enabeld and etherchannel interface is shut down. Then the roles are changed within 5 seconds.
