Using the 6355 as a PoE switch only.

[Anonymous]

The scenario is this.

I will be using MLPPP as access to my private network.

Is it possible to disable the DHCP on the 6355 (I have already deleted the pools) so that the DHCP on the private network can assign IP's using the MLPPP?

Can the 6355 actually do this from the physical interfaces Ethernet 0/0, T1 1/1 and 1/2? I know this can be done by using the GIG ports, but trying to minimize equipment and remove an obsolete T1 controller

Thoughts, Comments, and Questions are greatly welcomed.

Jack.

Can you please post config of the router as you have it now. (Do not include any private information you do not wish to share publicly)

Thanks,

Reference the UDP relay document to see if the ip-helper commands will help you. Assign the ip-helper address xxx.xxx.xxx.xxx command on the interface you want forwarding the broadcast packets. Remove "ip dhcp database local" and run the global command "ip forward-protocol udp bootps". This will forward any DHCP requests to the referenced IP under the interface you assign the ip-helper address.

example:

ip forward-protocol udp bootps

interface vlan 100

  ip address 192.168.1.1 255.255.255.0

  no shutdown

  ip-helper address 10.10.10.100

All DHCP requests from my 192.168.1.0/24 network will be forwarded to the 10.10.10.100 server as long as the router has routes (access) to the DHCP server.

Hope this helps.
