Need to add a simple switch with 2 VLANs.

I would like 23 ports to be switched together (1-22 and 24) Eth23 will only carry VLAN (11 and 12). Ether24 will have the 2 Tagged Vlans and Untagged data.

I need the 2 VLANs (ID 11 and 12) to be on ether23 and ether24 and all the untagged data sent to the entire switch except eth23.

Basic config example appreciated!
