[c-nsp] SPAN on Nexus 5k

[Виктор Моисеев]

We are using something like this on 5K.
We have some VPC to monitor on pair of 5Ks.

monitor session 1 
  source interface port-channel1012 rx
  destination interface Ethernet1/40
  no shut

interface Ethernet1/40
  switchport monitor

Are you sure that vlan9 traffic actually flows through 5k(B)?
>From your picture I see 4506 single-homed to 5k(A) only.
If so, you might want to use RemoteSPAN.
If 4506 dual-homed to both NXs via VPC
you can monitor port-channels on both of N5K.


Best regards,
Victor Moiseev
