[cisco-voip] CCM 6x licensing: which MAC to use for license when fault tolerance enabled

I bound the licenses to eth0.  When I later enabled failover, the bound interface took the MAC of eth0.  No problems with licenses.

When you enabled failover, your MAC address changed?

I believe it will still be eth0 same as if failover were not enabled.  I am awaiting confirmation from the licensing team.

Hi guys,

Cisco DOC says, you shud bind ETH0 MAC in CCM for getting license (feature or DLUs).

Situation1: Only using ETH0 (No fault-tolerance configured)

If server's ETH0 physical mac (when it was shipped) is EE:EE:EE:EE , the license will be generated using first ETH0 address.

I have tested this and works.

Situation2: (when fault tolerance is enabled)
Eth0 physical mac : EE:EE:EE:EE
Eth1 physical mac : FF:FF:FF:FF

When fault tolerance enabled, the mac on all interface becomes same:
eth0: CC:CC:CC:CC<----------this has changed from EE:EE:EE:EE
eth1: CC:CC:CC:CC <------this has changed from FF:FF:FF:FF
bond0: CC:CC:CC:CC <---------this is created once fault tolderance is enabled.

So in this situation, for licensing purpose - which MAC address should be bonded to make licensing work? and why?[cid:image001.gif at 01C98AA3.7206A430][cid:image001.gif at 01C98AA3.7206A430][cid:image001.gif at 01C98AA3.7206A430]

CC:CC:CC:CC  or  EE:EE:EE:EE        ???????????

I have the gut feeling, that EE:EE:EE:EE (the original hysical hard coded one) MAC shud use for licensing purpose....

Thanks in advance.
