I have an ASR 1002 that I have placed the following config on:
monitor session 1 type local
source interface Gi0/0/2 , Gi0/3/0
destination interface Gi0/3/4
I am not receiving any traffic on the destination port, is this really supported on the ASR?

Hello,
Please see below.

"The monitor session span-session-number type local command is not supported on Cisco ASR 1000 Series Routers."
Example snip: Monitor interface Gig0/0/0 traffic, and then send out through interface Gig0/0/1..
monitor session 10 type erspan-source source interface Gi0/0/0 destination erspan-id 10 ip address 10.10.10.1 origin ip address 10.10.10.1 monitor session 20 type erspan-destination destination interface Gi0/0/1 source erspan-id 10 ip address 10.10.10.1

Thanks for the information. Do you know why it is not support on the 1002? I am just curious why the command is excepted yet it does not work.

The ASR's architecture (RP, ESP, SIP, etc) and SW feature support is a little different than the 6500/7600 where you would normally use the local span feature. The command was removed in later versions of code to avoid confusion.
ASR1k(config)#monitor session 1 type ?
erspan-destination Encapsulated RSPAN Destination Session
erspan-source Encapsulated RSPAN Source Session
ASR1k(config)#do sh ver

Thanks for your help. I will give the ERSPAN config a try.
