I have 3750X stacked with 2 switches.
I am trying to span more than 1 destination, so I have the below configuration, but I don't see span traffic going to Gi1/0/22-24 (my server nic showing 0 receive). Only span that is working is the first destination, Gi1/0/12. Source and destination ports are all on the same switch.
Does anyone know what I am doing wrong? If it is not supported, any suggestion on how I can somehow span my internet to 3 different destinations? (I have 3 Websense servers that need to see all internet traffic).
3750X#sh run | i monitor
monitor session 1 source interface Gi1/0/11
monitor session 1 destination interface Gi1/0/12 , Gi1/0/22 - 24
3750X#sh moni sess all
Type : Local Session
Source Ports :
Both : Gi1/0/11
Destination Ports : Gi1/0/12,Gi1/0/22-24
Encapsulation : Native
Ingress : Disabled
That should be a valid configuration. Are ports Gi1/0/22 to 24 all going to the server? What is Gi1/0/12?
