If I have a dynamic interface that is connected to a subnet where the router interfaces have DHCP servers configured under the helper address commands, do I need to configure the DHCP fields under the dynamic interface configuration?
I have helper address configured on the connected routers AND these fields configured with the same DHCP servers.
Just wondering if I can take the IPs out of the WLC configuration?
Many thx indeed,
Ken, the DHCP address under the dynamic interface, is the address the WLC will unicast the DHCP request to when a client tries to use that interface. Under normal operation this address is needed. There is a way to get the WLC to bridge the packet to the wire so that it is a broadcast instead of a unicast packet. CLI command is config dhcp proxy disable.
But I do believe that even if you issue the CLI command, the software wants the DHCP address listed under the dynamic interface.
