Second NIC CCM

icabrera

Level 4

We are thinking about using the second NIC at a Call Manager server only for management purposes. The first NIC will work normally and the second NIC it will be used to access to the server remotely throught the VNC software.

Is this possible?

Thanks

Possibly, possibly not... either way it's probably not a 'supported' config :-)

Cisco always say the only supported config for dual-nics is fail-on-fault tolerance, i.e. active/passive config using the HP drivers (or whatever flavour box you have)...

If you tried it you would by definition have two IP addresses, and I'm not sure that you can force CM (or VNC) for that matter to bind to particular address - you also can't have two default gateways which may make setting up routes on the server itself complicated...

If you have VNC on one interface and CM on another chances are that not much you can do on VNC would fix whatever's wrong with the other interface, and if the other int was down you wouldn't be getting service from the server.

Why not just install VNC, and team the NICs? Put the interfaces on seperate switches in the same VLAN with redundant routes out and you have all the fault tolerance you need... for both CM and VNC.
