Can i use Internal DHCP on WLC Guest Anchor (5508) with Foreign HA 5508

[Kamran Barlas]

DHCP Proxy is required in order to use local WLC DHCP Pool (Guest Anchor), however reading Wireless Q&A (http://www.cisco.com/image/gif/paws/107458/wga-faq.pdf) states that both foreign and guest anchors must have :

In a Wireless guest access setup, the DHCP proxy setting in the Guest Anchor controllers

and the internal controller must match. Else, DHCP request from clients are dropped and you

see this error message on the internal controller......

However if you have N+1 you cannot use internal DHCP, does this also "grey" out the DHCP Proxy global setting? If so will the Guest Anchor still work with a internal DHCP pool even though foreign and guest controllers have a mismatch in DHCP Proxy (global) setting?

Many Thanks

Well it should still work... dhcp proxy is required on the WLC that has a dhcp scope.  With the newer code versions, you can enable dhcp proxy on a per interface do this doens't have to be global.

Cheers, wans't sure if in HA mode if the DHCP Proxy setting is disabled globally and unselected (i think this customer is firmware 7.4.100
