This is for a short temporary time until I get cisco 3560s in place. I have a 2921 configured and it is connecting to an HP non managed non VLAN switch and I cant get any traffic to pass from my computer to the router (pings or anything). Here is brief configuration that should be enough.
2921:
int ge0/0
no ip address
duplex full
speed 1000
int ge0/0.2
Management VLAN
encapsulation dot1Q 2
ip address 192.168.200.254 255.255.255.0
int ge0/0.192
Data VLAN
encapsulation dot1Q 192
ip address 192.168.2.254 255.255.255.0
int ge0/0.92
Voice VLAN
encapsulation dot1Q 20
ip address 192.168.20.254 255.255.255.0
Here are my vlans 1-default, 2-management, 192-data, 92-voice, i believe its running rapid spanning tree protocol. Do i have to take off encapsulation on my data vlan to get it to work or make the data vlan default vlan for everything. I am lost as to why this is not working. any help is much appreciated. i can get a config tomorrow if necessary
GE0/0 ---> HP Switch port ----> my PC. pc cant ping data vlan IP

If it's a non-vlan switch is it going to support trunking? You can try setting the data vlan as the native vlan (encapsulation dot1q # native) so that they're untagged. Maybe it'll pass traffic for just that vlan.

Excellent responses from all of you. I will try each of these starting from top to bottom and reply with which of them worked. looks to me like all of them would work just different ways of accomplishing the goal. Anyways I will reply.

I would have the ge0/0 in vlan 192 (sw ac vl 192) and the svi for vlan 192 as 192.168.2.254 255.255.255.0. Remove other ints on ge0/0 interface.

Here what I believe the hp switch is dropping the packets because they are tagged, you need to use access port and send untangled packet through the hp switch

You cannot trunk to a non managed switch , you can only have a single subnet on the router supporting the switch. If you needed more than a single range you could add a secondary address to the router interface.
