a pair of Cat9500-24Q running Fuji-16.8.1a release and configured for StackWise Virtual is connected FPR4110 ASA failover pair after a fresh boot switch #1 is ACTIVE and switch #2 is STANDBY and traffic is forwarded successfully over interface on ACTIVE [Fo1/0/1] as well as over interface on STANDBY [Fo2/0/1] ACTIVE unit is reloaded by executing "reload slot 1" command switch #2 becomes new ACTIVE we wait for switch #1 to boot up as STANDBY and reach SSO state from now on we are in problematic state traffic is successfully forwarded over new ACTIVE interface [Fo2/0/1] traffic is no longer forwarded over new STANDBY interface [Fo1/0/1] traffic that is supposed to leave via Fo1/0/1 is dropped on egress
a pair of Cat9500-24Q Fuji-16.8.1a stackwise virtual active unit rebooted
