How to configure SPAN from local and remote port

[Nguyen KeThuc]

Hi all,

Now, I have two cisco Switches ( 3560) ( Sw1 and Sw2).They connect to each other via trunk port. I want to configure span from port g0/1 in Sw1 and port g0/1 in Sw2 to port g0/2 in Sw1.

Could you show me how to configure this ?

Thanks

Hi Ganesh,

I reviewed your web page. I configured :

SW2(config)#Vlan 11
SW2(config-vlan)#remote-span
SW2(config-vlan)#exit
SW2(config)#monitor session 1 source interface Gi0/1
SW2(config)#monitor session 1 destination remote vlan 11

SW1(config)#Vlan 11
SW1(config-vlan)#remote-span
SW1(config-vlan)#exit
SW1(config)#monitor session 1 source interface Gi0/1
SW1(config)#monitor session 1 destination interface g0/2
SW1(config)#monitor session 1 source vlan 11
% Cannot add VLANs as sources for SPAN session 1

I also tried this command:

SW1(config)#monitor session 1 source remote vlan 11
% Cannot add RSPAN VLAN as source for SPAN session 2 as it is not a RSPAN Destination session

My issue is you cannot mix ports and VLANs in a single session. Do you have any ideas?
