I have read through the BCMSN Study Guide and Cisco.com product guide on ISR 3825 and that it supports SPAN on both routed and switchports.
I have a NM-16ESW on the 3825 but I hit a brick wall when I tried to SPAN a routed port with error message:
Interface FastEthernet0/8 does not support SPAN
Please, unconfigure it.
Does SPAN actually support routed ports or is it not supported in add-on modules?
my show run int fa0/8:
ip address 192.168.0.1 255.255.255.0
