DHCP and the VLAN
Posted on 2009-07-10
We have two sites, one central site with a CISCO call manager, and a DHCP server. One remote site with users and Cisco phones. The phones are on a VLAN seperate to the DATA network at the remote sites.
I know all bout DHCP helpers etc. However my question is this:-
If the PC gets it IP from the Router via DHCP, how does the phone "know" to go down the link to the head office to contact the DHCP server there an not use the DHCP from the router?
