Cisco Bug: CSCsz30314 - ES20-Multicast ingress queue wedged
Jan 24, 2017
- Cisco 7600 Series Routers
Known Affected Releases
Symptom: An ES-20/SIP600 line card interface may start dropping multicast frames destined for the router. This will prevent protocols dependent on multicast hellos/keepalives from functioning on the interface. It is also possible that Xconnect/VPLS end to end mac learning doesn't occur. Conditions: It could happen under erroneous circumstances when lots of fabric errors are seen on ES20/SIP600 line cards.
