[Rutis, Cameron]

John, can you share a bit more about the automation you mentioned?

Yes, we CNAME the device.[sub].domain.com to the correct management interface (whatever it is) on the device.

So sometimes we manage via loopback, sometimes via dedicated management port, and sometimes via another interface (gig1/48).

We automated a tool to generate all the DNS records for our interfaces, and just track which interface should be used to manage the device and CNAME to it.

Thanks for both the answers so far.

My biggest issue however is with the management/ loopback interface.

Does everyone just use a cname for the switch/ router name - and the reverse lookup for this address is then the 'real' interface name?

Thanks

Andrew
