Cisco 4506 IP Routing not enabling

I am trying to configure a Cisco 4506 with software 12.2(37)SG1 to route IP traffic. When I type the ip routing command, it seems to take it with no complaints, but then it does not show up in the config. Since I cannot ping between internal interfaces, I assume it is not really routing. How can I get the ip routing to stick? Attached is the current config

Please post result of " show ip route" and " show ip interface brief" commands and also tell which interfaces are you using for the ping test?

Are you able to telnet to the switch? If yes, from which interfaces?

starting back around v11.0 "ip routing" is a default configuration. So it will not show in the config.

How are you pinging "between internal interfaces"?

I was attempting to ping any of the interface IP's via the console cable. Also, i attempted to plug into one of the 208 ports but was not able to pick up a DHCP address (so I assumed it might have to do with the routing)

If the DHCP server isn't on VLAN 208, you'll need an ip helper-address pointing to the server.

As for pinging an SVI (VLAN interface), if there are no active ports in the VLAN, the SVI will not be up.

If you troubleshooting DHCP, then test with two devices that have IP address manually configured. That would prove routing.

Where is your DHCP server located?

I will test with static IP's on Monday.

The DHCP server is configured on the same switch (see attached config). Can you tell why DHCP isn't working?

Your DHCP settings look correct.

Try adding:
ip dhcp database flash://dhcp.txt

or

ip dhcp database slot0://dhcp.txt

depending on your switch

Fixed it. The problem was that the VLAN's were not added. I thought that once I added the interface with a VLAN assigned, the VLAN would exist within the switch. Once I added the VLAN's on their own, the routing and DHCP server started working.

Thanks all.
