CUCM 8.6 VMWare changind gateway on sub

Hi - we have a 4 x node 8.6.1 cluster running on ESXI 4.1 on C210-M2 hardware.  We have licensed the cluster based on the new VMware licensing requirements using the new licensed MAC process:

http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/virtual/servers.html#wp81227

We now require to change the default gateway on one of our subscribers, I am guessing the hashed licensed MAC  is relative only to the Publisher / License Manager server, .i.e we cannot change any of the below on the Publsiher without voiding the cluster licenses:

•Time zone

•NTP server 1 (or "none")

•NIC speed (or "auto")

•Hostname

•IP Address (or "dhcp")

•IP Mask (or "dhcp")

•Gateway Address (or "dhcp")

•Primary DNS (or "dhcp")

•SMTP server (or "none")

•Certificate Information (Organization, Unit, Location, State, Country)

But we are ok to change the default gateway on our subscribers without causing any license issues?

Thanks

Brian

Hi Brian,

You should be good to go here If for some strange

reason this did have some effect in the license MAC you would

still be covered;

Customer Impact from New Licensing Procedures

#

Cisco Unified Communications Manager on VMware on Cisco UCS B-Series Blade Servers uses a different licensing model than Cisco Unified Communications Manager on an MCS server. The MAC address of the NIC card is no longer used to associate the license to the server.

#

Instead, the license gets associated to a license MAC, which is a 12 digit HEX value created by hashing the following parameters that you configure on the server:

#

Time zone

#

NTP server 1 (or "none")

#

NIC speed (or "auto")

#

Hostname

#

IP Address (or "dhcp")

#

IP Mask (or "dhcp")

#

Gateway Address (or "dhcp")

#

Primary DNS (or "dhcp")

#

SMTP server (or "none")

#

Certificate Information (Organization, Unit, Location, State, Country)

This hash of these fields is called the LICENSE MAC

Note : Once there is a change in any of the parameters that creates the License MAC, it will

give you 30 day grace period to generate a new license file for the CM based on new license

MAC.

You are correct, all CUCM licenses are only based on the Publisher Virtual MAC, so making changes on Subscribers will not affect any licensing.

HTH,

Chris
