I tried to SPAN 3 source ports into a single destination port in a Cisco 3750 stack stack. Each time after I added the monitor session 1 destination statement, the destination port line protocol went down even thought a PC is connected. What is wrong with my configurations?
Switch stack consisted of 4 WS-C3750G-48PS 12.2(25)SEB4 C3750-IPBASE-M
There is nothing wrong with the config nor with the status of 2/0/37. When a port is configured to be the destination of a monitor session, it is ment to monitor only and not to work as a regular port, reason why it was designed to stay as protocol down. Afterwards, the ingress command was added to get a destination port to receive traffic from an specified vlan however the line protocol status will remain the same (down).
