Hello All,
When trying to configure ERSPAN on a ASR1006, I'm not getting any traffic on the destination port. ERSPAN flavour is LOCAL SPAN, as described in:
http://www.cisco.com/en/US/docs/ios-xml/ios/lanswitch/configuration/xe-3s/lnsw-conf-erspan.html#GUID-4FF72FB4-CDC4-40CC-AA25-E32C8CE58E95
Configuration used, is the following:
monitor session 1 type erspan-source
no shut
source interface GigabitEthernet0/0/2
destination
erspan-id 10
ip address 10.10.10.1
origin ip address 10.10.0.1
monitor session 2 type erspan-destination
no shut
destination interface GigabitEthernet0/0/3
source
erspan-id 10
ip address 10.10.0.1
Output from “show monitor detail”:
ASR1K_1#sh monitor detail

Apparently everything is configured in the proper way, however I’m not getting any traffic in the destination port. Also I’ve noticed the following in the details from ‘Session 1’:
Destination IP Address : 10.10.10.1
That doesn’t make much sense to me.
Could anyone help me understand how to configure Local SPAN using ERSPAN?
