Hi,
Some of the things you could dig into further to look for any transitiions and anomalies in receive v/s processed & drops:
show virtual-chassis protocol adjacency detail show virtual-chassis protocol statistics all-members
Also, you could try reconfigure the vcp port:
request virtual-chassis vc-port delete fpc-slot 0 pic-slot 1 port 1
request virtual-chassis vc-port set fpc-slot 0 pic-slot 1 port 1
Quite weird for the vcp port to be Up on one side and down on the other. I guess it would be operational Down due to some protocol issue
Cheers,
Ashvin
