Does someone knows if co-resident ELM also requires and static MAC address on the CUCM?

 

Thanks

Products that handle their

Products that handle their licenses via ELM/PLM no longer have a License MAC, and the MAC from the vNIC has no relationship to licensing. The licenses are tied to the ELM/PLM server.

Hi JaimeELM uuid is

Hi Jaime

ELM uuid is calculated (partially) using the MAC address of the underneath server. In case of a co-resident server, ELM uses CUCM mac address (VMware assigned MAD address). VMware allocate a dynamic mac address (by default) to each VM. That MAC can change over time (when specific changes are made) and as a result  an ELM uuid will change and  will invalidate all licenses.

That's why I think MAC address on a co-resident CUCM (CUCM+ELM) should be static.

 

My logic is correct?

Alex.

Hi Alex,  what can be said is

Hi Alex, 

 

what can be said is that UUID gets changed when you move ELM from one server to other server? . In that case, license needs to be re-hosted.
