Note: You cannot track CFS updates on a per-group basis. However, if vPC peers are out of sync, you can verify that 
CFS messages are properly being sent and received via the following command.  

 

VLAN 111 IGMP snooping statistics, last reset: never (only non-zero values displayed) 

  Packets received: 418 

  IGMPv2 reports received: 209 

  IGMPv2 queries received: 209 

  PIM Hellos received: 1737 

  Packets sent to routers: 209 

  VIM IGMP leave sent on failover: 0 

  vPC Peer Link CFS packet statistics: 

      IGMP packets (sent/recv/fail): 209/0/0

2.  Once the IGMP join is received (either directly or via CFS from vPC peer), the Layer-2 VNI (16100) + group infor-

mation (225.1.23.111) will be added to the fabricpath mroute table. Verify that the CE VLAN to Layer-2 VNI map-

ping is correct, and that the proper interface is added to the Layer-2 OIF list.
