Unable to setup udp forwarding (DHCP server is enabled)

Jump to solution

Hello,

I'm running x3 1638s in ActivChassis with R10-7-0 firmware.  I recently setup several VLANs, tested connectivity with static ip's, setup a dhcp server within the Netvanta and all worked just fine.  I removed all dhcp information from my config and attempted to turn on UDP relay (to forward dhcp requests to my Domain DHCP server) and received the error "%Unable to forward bootps because the DHCP server is enabled".

I confirmed there is nothing in the config (I can post if requested).  Also, if I run a "show proc cpu" I see DHCP Server is running.

Am I missing something?  How do I stop the DHCP Server?

Thanks!

I'm not sure why that would be happening, but you can program DHCP relay into each of the VLAN interfaces.  This is with the assumption that you are using VLAN interfaces and not just VLANs.

int the given interface that you want to relay DHCP requests, issue "ip dhcp relay destination X.X.X.X" statement.

The interface will relay all of the DHCP requests seen on that interface  to the X.X.X.X address.

This will happen even if DHCP is running on the switch.

Funny thing is, I tried that yesterday.  It would take hours of testing to finally figure out that I forgot to "activate" the scope on my dhcp server.

Mondays suck.

Thank you.
