[cisco-voip] RTMT SDL Link Out of Service

[Chris Ward (chrward)]

SDL links are used between CCM, CTI, and CMI services to share data regarding the current status of devices and to send calls to and from different nodes in the cluster. They form a full mesh between like and dislike services. I.E. CCM on node 1 will have an SDL link to CCM on node 2 and to CTI on node 1 and 2 and so on.

 

SDL links going out of service usually represent a network outage between the nodes or a service crash on one of the nodes. Any core files in RTMT?

 

If the alert isn’t continually re-firing, then the link is probably operational again.

 

HTH

Subject: [cisco-voip] RTMT SDL Link Out of Service

 

My RTMT reported the SDL Link out of service between two of my CCM servers (servers at different locations).  

Not entirely sure what SDL Link is or does and more importantly, how to determine if it is back up.

 

I do not appear to be having CCM problems anywhere in the environment; just wondering if anyone could offer some cliff notes on the SDL service 

 

Thanks in advance
