Subject: [c-nsp] 6500 VSS question

All,

        Noticed an unexpected result today when testing VSS failover.  Our 
setup has dual sups in each chassis, with a supervisor port of each chassis 
connecting to the matching supervisor port on the other chassis, i.e. 1/5/4 
connects to 2/5/4, and 1/6/4 connects to 2/6/4.  Today when pulling out the 
active sup, the hot-standby took over immediately as it should, but we noticed 
all the linecards in the chassis with the pulled sup resetting.  I was under 
the assumption that a sup transitioning from RPR-warm to standby hot would 
remain forwarding at L2, thus keeping the VSL up.  Now I'm questioning that.  
It would explain the result, as the linecards couldn't get to an active 
supervisor.  I'm thinking I should have a third VSL link (of that port channel) 
on a non-sup linecard.  When we did the eFSU, we noticed real long outages of 
the linecards of the chassis getting the final reload as well.  Possibly the 
same issue, no connectivity to the active sup?

Thanks,

Chuck
