Trouble with DHCP on single VLAN

[jshea]

I'm having trouble with DHCP assignment on a single VLAN on our system.  If someone could point me in the right direction to get things working correctly again, I would greatly appreciate it.

Hi

 Sure you can get help here, just provide a bit more information. 

    I suppose this vlan is installed in a access switch and then you have a core switch. Does this core must have the interface vlan. Do you have ip helper address on the Core?  Or the core is the DHCP server for this vlan?  

Is it a real environment or simulator?

I'm happy to provide any information that I have.  Please bare with me, I'm very new to this.

I don't know that I have a core switch.  I believe the VLANS are setup directly on the router.  I wasn't left any information on how to access the interface VLAN.  The core functions as the DHCP server.  The environment is real.

I inherited the system and have to bandaid it while I rebuild it...

right. Can you share this routers config here? show running-config ?

There is no GUI on the router for me to access.

I'm looking into replacing the router entirely because it is 10+ years old.  I know that I'm not going to be able to provide enough information for a guaranteed solution, but any new direction (or educating) will definitely help me get to a solution.

I was not expecting the GUI but command line. Pretty shre any cisco router supports it. But you need to have either console cable or network connectivity and credentials.

Get in the black screen and issue the command  "show run" and send here the output.

How about consoling into this router and pulling don its running config so we can get a clearer idea of the problem?
