Description (partial)
Symptom: Upon physically removing the active SUP from the switch, Multicast and Unicast packet loss for 60 seconds until route convergence takes place. Conditions: Default route is learned via SUP uplink interfaces: Te5/1 and Te6/1(ECMP). ECMP (Equal Cost Multi Path) is affected by physical removal of the active SUP and causing SSO to standby SUP. Only that ECMP path that is taking TenGigabitEthernet ports on the SUPs is affected. Any ECMP with line card ports is never affected.
