[c-nsp] DNS Naming conventions for Switches

[cisconsp at SecureObscure.com]

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
