I didn't take to much time to look it over so my reply may be premature, however...

1)It looks like you gave us two switch configs, and not the router.

2)You have a layer 2 switch configured with more than one SVI, which is not possible. (Do a 'show ip interface brief' and see if they are 'up and up', the probably are not.

3)The point of doing router on a stick is when you cant do layer 3 switching you can still do inter-vlan routing. Configuring more than one SVI on the switch kind of makes ROAS useless. (Should note though, you CAN'T do layer 3 switching with the 2960.)

We need a router configuration
On the switch enable only one native vlan
on the router enable subinterface with native vlan
on the switch enable deffault gateway-native vlan on router

Should the native vlan be made something like vlan 99? and then for the trunks should the command be entered for switchport trunk native vlan 99 be entered?

edit: oh and the native vlan and management vlan don't have to be the same but can be right?

Vlan native can be 99 but doesn't need to

Vlan native can be 99 but doesn't need to. Yes native vlan and managment can be the same

It's not that it's not possible, because it is. It just won't route between the vlan's.

What he means is that you can't have more than one SVI up/up in a layer2 switch. You can configure as many as you want, but only one is going to be accessible at a time

You don't even have to have a native vlan, native vlans are only there to transverse un-tagged frames. Basically you need 1 vlan ip address, this will be used to access the switch via ssh / telnet or to ping. You need a trunk statement on your uplink (switchport mode trunk, switchport trunk allowed vlan 1,2,3,4,5,etc). Then you need to put the ports into the proper vlans (or configure the native vlan on the switch uplink). Then on your router you need to configure sub interfaces with dot1q tagging option since its layer 3 (if you use a layer 3 switch such as 3650 / 3750 you have to use this statement as well on the trunk lines).

I know exactly what he meant, I was just being facetious.

Yeah, but a new guy reading the forums might not, hence my clarification
