Router on a stick with 3024
I need to route between 2 vlans on a powerconnect 3024. I created the second vlan and removed the U from the default vlan on the ports for the second. I added the U on the ports for the second vlan. I set the PVID 2 for the ports on the second vlan. My questions are:
1)How do you set the port with the router? I set that port to T for both vlans. I have a cisco 1721 router setup with sub interfaces:
interface FastEthernet0
no ip address
speed auto
no cdp enable
!
interface FastEthernet0.1
encapsulation dot1Q 1 native
ip address 172.18.1.1 255.255.0.0
!
interface FastEthernet0.2
encapsulation dot1Q 2
ip address 192.168.0.1 255.255.255.0
2) Do I need to enable trunking on the port for the router? Or will puttint them in a "T" status for both Vlans be enough?

I can only find this thread on the topic and it doesn't specifically explain the settings needed for the router on a stick configuration.

For a "Router-on-a-stick" configuration, you need to trunk all VLANs across the uplink to the router. On the 3024, you would simply tag (T) all VLANs on the uplink port to the router. The PVID on the uplink port is the native VLAN. For trunking to work properly, the native VLAN must be configured the same for the ports on the switch and router (typically VLAN 1).
If you have configured the 3024 this way but the routing is not working, there is a configuration problem on the router. I'm not familiar with the 1700 series but to configure a "Router-on-a-stick" using VLANs on a 3550, you would bind the gateway IP address to the VLAN and simply trunk the uplink port.

There is no generic "trunk" mode configuration for the 3024. Tagging the port (by putting a T for that respective VLAN) is the same as "trunking" that VLAN on the port.

Ok thanks for the quick response.
