Hello,
We've upgraded our juniper ex4550's in virtual chassis to version 15.1R6-S2.1. Everythig seems to be fine but one thing.
Our aim was to have a simple way to get vc-port statistics over snmp.
The only command in new junos version was configured is "set virtual-chassis vcp-snmp-statistics".
But the result seems to be incorrect, for example:
show virtual-chassis vc-port statistics

and snmp returns different values:

If we campare snmp results to physical vcp-255/x/x interfaces (show interfaces vcp-255/x/x statistics detail) the values are equal.
So, it seems that snmp returns physical but not virtual (which it should) port statistics.
Do we miss something ?
