ASR and suspending critical services

[markusmaximus]

Hi All

I have two old CSS 11500 that are doing nothing but providing load balancing for 2 terminal servers.

As per the documentation, I setup my ASR config (at least i think its right).  I'm now faced with two problems:

Problem #1:  If I suspend the first Terminal Server service on CSS-1, CSS-2 takes over and continues to allow connectivity until the service on CSS-2 is suspended.  Is this normal behavoir?

Problem #2:  Once I suspend the service on both servers, My rule goes down.  Show summary says the state is down and I cannot access any terminal server at all.  I am assuming this is because I have them configured as critical services, can anyone confirm?  If so, what is the process to suspend a service temporarily?

One other question,  I have been using in testing balance aca (configs below are set to leastconn), but i'm not sure if it will work with RDP.  Can anyone confirm?  Should I instead be using leastconn or one of the others?

Many thanks!

The critical service should be  an upstream/downstream device, not the services that you are using for loadbalance. That's why the CSS failover everytime you suspend one of the services.

Here are more details about it:

The VIP is INSERVICE when at least one of the services in the Content Rule is Alive.  If all the services in the Content Rule are down, the VIP address will be down as well.
