Hi,

We have a Cisco Catalyst 2900 XL switch with about 10 different VLAN's on it. We would like to be able to create a SPAN so that all 10 of these VLAN's go to one destination port for our IDS to monitor. Is this possible on the Catalyst? How would I configure this?

Thank you

just make the vlans your source in your monitor session:

Switch1(config)#monitor session 1 source vlan 1 - 100 rx

The example above will monitor vlans 1 through 100.

Use commas if if you want to do something like:

Switch1(config)#monitor session 1 source vlan 1,5,8,15 rx

Oh, okay. So I can monitor multiple VLANS and output it to a single port?
