changing subnet mask on cucm

[abukuru95]

Hi Guys, i am try to put up a wider IP address range by changing the subnet mask for the voice vlan. I will be keeping the same IP addresses.

what impact will this have on the system ? DO i have to ask for license information from Cisco again after i restart the server?

i am running CUCM 7.1 and i also have to make the change on meeting place and CUC.

any advice is highly appreciated.

For CUCM 7.1, the license is based on the MAC address of the Publisher.

Therefore there is no need to ask for a license rehost to the TAC.

Bear in mind that if you change the Subnet Mask, your default GW might also change.
