Hi Rohan,

"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 "

Yes, you can.  It's NIC teaming but only for failover.  From the CLI, issue "set network failover enable".

Hi

No - the licensing system is clever enough to just take the first NIC physical MAC rather than the virtual team MAC. So nothing changes.

Guys,

I have a issue with the NIC teaming..

Fault tolerance is configured in my cucm.

I'd like to set the Speed and Duplex from the CM's End..

iI've added the Show network failover



admin:show network failover

eth0 has been overridden by Network Fault Tolerance.

To view the Ethernet port configuration, please use following command:

show network failover

admin:show network failover

Bond 0

DHCP         : disabled           Status     : up

IP Address   : 138.241.118.34     IP Mask    : 255.255.255.224

Link Detected: yes                Mode       : Auto disabled, full, 100MB/s

Ethernet 0

DHCP         : disabled           Status     : up

IP Address   :                    IP Mask    :

Link Detected: yes                Mode       : Auto enabled, Half, 100MB/s

Ethernet 1

DHCP         : disabled           Status     : up

IP Address   :                    IP Mask    :

Link Detected: yes                Mode       : Auto enabled, Half, 100MB/s

DNS

Primary      :                    Secondary  :

Options      : timeout:5 attempts:2

Domain       : localdomain

Gateway      : 138.241.118.33 on Ethernet bond0

---------------------------------------------------------------------------

Now i need eth0 to be set to Full dupled and speed 100MB/s

would using the command #set network nic eth0 speed/duplex  solve my issue...

Any help highly appreciated...

Thank you guys
