CSM Support for DHCP

[drussell]

Is is possible for servers in server vlans to get their addresses via DHCP? I don't see an IP helper command for the CSM.

[Gilles Dufour]

you would need to configure bridge mode on the CSM.

In this mode, DHCP traffic would simply be bridged through the CSM.

Thanks for the reply.

Is there a Cisco best practice defined for using bridging mode vs router mode?

What factors do you consider when selecting the mode?

[Gilles Dufour]

actually the #1 factor is the type of traffic that you want to go through the CSM.

The CSM does not support certain type of traffic but it is able to bridge it.

DHCP, multicast, ospf,...

If you have these requirements, you should go for bridging mode.

Routing mode is more like the easy solution.

Easy to implement, easy to troubleshoot.

Bridging requires a little bit more attention.
