I'm trying to set up an 802.1q trunk between the buit-in 10meg ehternet port on a 2611 router and a cat 3524 switch. I am running release 12.2(11)T10 on the router. The subinterfaces will come up but I can not ping any devices on the vlans on the switches.
I know that 802.1q was not supported on the built-in interface till 12.2(2)T but should be with my version.
Are there any special caveats for configuring 802.1q trunking on these interfaces?
