CSS load balancing, service dependancy condition check

Question

Hi,
I would like to seek some advice regarding the CSS's service configuration.
Is there a way to configure the CSS such that it check for the condition/status of a independant service (not involved in the load balancing algorithm) is alive/down (using service mode keepalive port/type), before deciding whether to/not to load balance to a group of services?
Senario is as follwows:
We process incoming HTTPS request and load balance to 2 HTTPS Servers (HTTPS service SSL1 and SSL2), on condition that a independent service (HTTPS service SSL3) is alive (using the keepalive type/port check in service mode).
If the independant service (HTTPS service SSL3) is not alive, remove the HTTPS Servers (HTTPS service SSL1 and SSL2) from the load balancing algorithm.
Thanks in advance for assistance

? This is the service condition that CSS will check before deciding to/not to load balance to SSL1 and SSL2.
? If SSL3 is down, do not load balance to SSL1 and SSL2. If SSL3 is up, load balance to SSL1 and SSL2

Answer 1

maybe this?
circuit VLAN1
ip address 192.168.103.35 255.255.255.192
ip virtual-router 10 priority 100
ip redundant-vip 10 192.168.103.37
ip critical-service 10 SSL3
if I'm not mistaken the vip 192.168.103.37 will stop working when the service SSL3 goes down. I'm not sure that this is what you want though...
