Redundancy in Cisco VSM

[Yhya Akef]

Hi ,

Is there Redundancy in cisco VSM ( 2 VSMS servers redundant to each other same as call manager ) ?

Dear Yhya

Redundancy/HA is not supported on the current VSM release. You can achieve some level of high availability using methods like; configuring cold standby server, having dual streams or using child/parent proxies. However ,as I mentioned on my previous posts this is not a full HA solution.

I've developed a warm-standby configuration that allows a failover within 5 minutes of a primary failure.  It was /not/ easy, and is wholly unsupported by Cisco TAC.
