RSPAN and ARP Packets

Jan Linhart
Level 1
Level 1

Hello, I am trying to solve DHCP issue with DHCP decline and experiencing problem with RSPAN.

I have set RSPAN montor session and I monitor traffic on my laptop in another building.

All traffic from source interfaces is mirrored, except ARP packets (which are really important in solving this issue).

Is there a way, how to mirror L2 packets with broadcast destination mac address?

 

Source - Catalyst 4500

monitor session 1 source interface Gi1/33
monitor session 1 source interface Gi3/40
monitor session 1 destination remote vlan 222

 

Destination - Catalyst 3750

monitor session 1 destination interface Fa3/0/45 encapsulation replicate
monitor session 1 source remote vlan 222

Thank you, Jan
