beginner issue with connecting AD tran to network

I am a bit confuse on how to confiure ad tran 908e 3rd gen to forward dhcp requests to our server.  I currently have our dhcp server set up on a switch.  The ad tran is on another switch with gateway of xxx.xxx.4.1.  set up udp relay to point to the dhcp server ip address using bootps. 

What I do not quite get is how to configure the eth0/1 port to connect over to the the other switch or what routing I might need.

Any suggestions would help.

Thanks.

Re: beginner issue with connecting AD tran to network

Very helpful for setting up relay.  Thanks.  As far as setting up the eth 0/1 interface does its IP need to be the same as the the one the dhcp is on?  For example if my dhcp server is on 10.0.0.0 network does my interface need to have an address of 10.0.0.?.  this is a simple ptp setup for testing the dhcp relay capabilities.  so the dhcp is on its own switch and the ad tran and a lone pc on another.

Thanks

Re: beginner issue with connecting AD tran to network

The whole point of using DHCP relay is that your DHCP is on a different logical network. So eth 0/1 needs to be a different network like 172.16.10.0/24. Then you can put the DHCP server upstream from the ADTRAN on the 10.0.0.0/24 network out the T1 or other Eth interface.

Does that make sense?

Re: beginner issue with connecting AD tran to network

Ok I have tried everything I can to get the dhcp relay to work but with no success.  I have simplified my setup but still need help.  I have the gig 0/1 interface set at 10.10.2.1,  I have the eth 0/1 interface set for 10.10.0.254.  the Dhcp server is connected directly to the eth 0/1 and has an IP of 10.10.0.207.  I plug my laptop into the gig 0/1 port and it cannot get an ip address from dhcp.  I have set the relay on both interfaces no success.  Any suggestions?

Thanks

Steve

Re: beginner issue with connecting AD tran to network

What is your DHCP server’s default gateway?

From your device on gig 0/1 interface, see if you can ping the dhcp server 192.168.0.207

Or from the adtran do this:

Ping 192.168.0.207 source 192.168.2.1

You need to remove this command, you put the address of the adtran:

ip default-gateway 192.168.2.1

remove it by putting no in front of it. That command is for switches not routers.

You might have a routing issue if your devices can’t ping each other.

Then remove this commands, just copy and paste into your config-t prompt, they are not needed if you have the dhcp relay command on your eth interface.

No ip forward-protocol udp time

No ip forward-protocol udp nameserver

No ip forward-protocol udp tacacs

No ip forward-protocol udp tftp

No ip forward-protocol udp netbios-ns

No ip forward-protocol udp netbios-dgm

After you make those changes, try and ping again. Let me know the results.
