Dear Team,
Anyone have the experience for monitor the vlan traffic across 2 Nexus 6k switches? My scenario are 1 of the monitor server are direct attached to the 1st unit of N6k intend to monitor 2 vlans, but this 2 vlans are span across vPC where it can be transit across both units of N6K according to the vPC traffic flow methodology. I can easily span the local N6K from the 2 vlan to the destination (monitor server) ports, but how I could monitor the traffic (for that 2 vlans) arrived on 2nd unit of N6K?
I try searching for N6K doc there is no RSPAN feature but now introduce ERSPAN, but ERSPAN got limitation stated •
A destination port can only be configured in one SPAN session at a time.
Meaning I can't configured both local SPAN and ERSPAN at N6K unit 1 to the same destination port to monitoring server?!!!
Just wish to know is any experts came across this scenario and have experience on alternative solution, would like to hear from your expert advice, thanks in advance.
Regards
Chong
