Teaming in CUCM

[allwyn.reuben]

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 "
