Hi we have Call manager cluster with 2 NIC in each server. we want to do teaming of both the NIC interfaces in each server for redundancy purpose..
Can someone guide me how to do that. as per my understanding is the below command is enough to do the teaming or any other else needed ?
"set network failover enable".

Hi
That command is all you need. The two NICs go in active/passive failover mode, so just need to be connected to the same VLAN... no other specific switch config required.

Hi Allwyn,
That is correct my friend
"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 "
