I have configured Span port on our 4510.
We have an application 5view server to monitor trafic connected to G9/17
Since we have changed the network connection from physical Giga port and add a Port-channel instead, we don't see any more trafic from the new Port-channel to G9/17
We have the configuration below on our 4510 :
monitor session 1 source interface Gi4/6
monitor session 1 source interface Po20
monitor session 1 filter vlan 311 - 312 , 375
monitor session 1 destination interface Gi9/17
From the commands show, we don't see the trafic duplication from the source to the destination port :

. Does anyone have any suggestions ?
I have attached the show monitor session and show version
Best regards

Try this:
no monitor session 1
monitor session 1 source interface Gi4/6,Po20 both
monitor session 1 destination interface Gi9/17 encapsulation dot1q
monitor session 1 filter vlan 311-312,375
Hope this helps....
