Hello,

As per CUCM 7.X SRND

"NIC Teaming for Network Fault Tolerance

The NIC teaming feature allows a server to be connected to the Ethernet via two NICs and, therefore, two cables. NIC teaming prevents network downtime by transferring the workload from the failed port to the working port. NIC teaming cannot be used for load balancing or increasing the interface speed.

Hewlett-Packard server platforms with dual Ethernet network interface cards can support NIC teaming for Network Fault Tolerance with Cisco Unified CM 5.0(1) or later releases.

IBM server platforms with dual Ethernet network interface cards can support NIC teaming for Network Fault Tolerance with Cisco Unified CM 6.1(2) and later releases. "

And the command to do that as per the CUCM OS CLI Reference Guide is:

"set network failover

This command enables and disables Network Fault Tolerance on the Media Convergence Server network interface card.

Command Syntax

failover {enable | disable}

Parameters

•enable enables Network Fault Tolerance.

•disable disables Network Fault Tolerance.

Requirements

Command privilege level: 1

Allowed during upgrade: No "

The referenced guides:

CLI Ref

I've personally done it only with HP servers but guess it would work with IBM too.

Does this setting survive across restarts of the server?

Because of the short outage involved, I would hate to have to perform it every time the server is restarted.
