I have two subnets, my voice and data. The two subnets are bridged and are using different DHCP servers. I use PXE services (3com boot services) which also uses TFTP on my data subnet. The voice subnet only has phone server TFTP.
My question is, how do I configure my data subnet for the CCM TFTP servers WITHOUT loosing my PXE boot abilities?
That is not recommended, one very specific purpose of running separate voice and data vlans is to separate the domain of respective dhcp/tftp servers.
Of course you can integrate the dhcp/tftp servers into one single system with the appropriate configuration, but still is suggested to keep separate vlans in order to know what is what and from where it comes.
provides the directions for adding an option on the DHCP server to point phones to the call manager TFTP server. Apparently option 150 is not used by bootp or PXE and I was able to have both my phones and PXE server on the same subnet without problems. Can we give points to ourselves? ;)
