Trunking

[24]

Guys,

I want to create a vlan on my cisco 4000 cat-os switch, and trunk it through my 7200 router so i can communicate between the 2 vlans, then put an access list on the trunk port to limit the ports which it can comunicate on.

I only have 1 connection from the switch to the router, can this be my trunk port and let the other traffic through as well. Can I create a sub -interface to put my ACL on???

Hope this makes sense.

Rob
