Callmanagers redudancy !!

[Ahmed Nasry Abdul Shakoor]

Hi all,

I have two core switches

Switch A and Switch B

one publisher and one subscriber ......

publisher and subscriber each has two lan cards, i have to configure redundancy between both interfaces of each server !!! i mean first network port of publisher will connect to Switch A and other network port will connect to Switch B.. same like for Subscriber also, first network port of subscriber in switch A and other in Switch B ... do i need to configure redundancy on servers also ??? how we can configure redundancy !!!!

Regards

since there is no version on the post

open the appropriate OS guide

Maintain and Operate Guides

http://www.cisco.com/en/US/products/sw/voicesw/ps556/prod_maintenance_guides_list.html

go to CLI commands and look for set network failover

Notice support depends on version and server brand (again, none of that on the post) so if you need more info look on CCO the release notes.

if this helps, please rate

If you are running CUCM 5.x and higher, the Linux command is set network failover enable, you may have to reboot, but I cant recall. That's it for CUCM. If you are running 4.x, the Cisco OS does support HP NIC teaming from what I remember, but only Active/Standby or Network Fault Tol.

It's not turned on by default.
