Activate NIC teaming on Unity Connection v8.x , what with license?

[david.vanherck]

Hi,

We have a Cisco Unity Connection v8.0.3a running without NIC teaming. What will happen if we activate the NIC teaming? A License MAC will be generated, so the old licenses won't work anymore? Will Unity Connection continue to work for 30 days after as in VM's? Granting us some time to have a new license for our Unity Connection...

Greets,

David,

You should be ok to activate network failover on your UCXN server.   I don't believe UCXN uses License MACs like UCCX does.  As far as having 30 days after a license expires, I'm not sure.   I thought you'll have to restart the Connection services but I might be thinking of Unity.

The virtual MAC address used for licensing should not change if you enable NIC teaming.

I have done this a few times without problems.

You should not need to rehost the license or even restart any services.

Hi,

Thanks for the feedback! :-)

I've read some info in the "System Administration Guide for Cisco Unity Connection Release 8.x", chapter "Managing Licenses in Cisco Unity Connection 8.x" where they talk about licenses on Physical Servers: http://www.cisco.com/en/US/docs/voice_ip_comm/connection/8x/administration/guide/8xcucsag310.html#wp1074732 Here they state that the MAC address of NIC1 is duplicated to NIC2.

I checked our CUCM, where we activated failover during installation and this is what we have:

So the NIC1 is similar to NIC2 and also the Bond0 is the same MAC address. The License MAC is identical to Bond0, so all MAC addresses are the same if you activate failover.

We hope that this is also the case for Unity Connection, but this we'll now this weekend ;-)

Thanks for helping me! :-)
