CUCM Pub IP Address Change

Unanswered Question
Jul 15th, 2009

Hi - We currently have a single site 2 node (1xpub and 1xsub) CUCM System

version: cluster.

Our customer has requested we re-address both the subscriber and the publisher to

accommodate their new address scheme. I have followed the doc


and successfully changed the server ip and eth0 ip on the subscriber, however, when we try

to change the IP address on the Publisher using either the web ui (Settings > IP >

Publisher) or cli (set network cluster publisher ip) commands we recieve the error:

"This machine is the publisher and therefore the IP address cannot be modified. "

Can you help?

I have this problem too.

Hi - sorry, my mistake here, these commands should actually be run from each subscriber and not the publisher.
