I am load balancing three routers using the CSS11150. I have setup the three routers as primary, secondary and tertiary services. The routers feed X25 lines with the route determined by the port number. Everything works fine until I get above 100 services and then services do not go active. I can enter content rules okay but the services are down. The external connections are connecting to the vip address and specified port number (9000 - 9500). Have I hit the limit on the CSS and if so what do I need to upgrade to?
Config:
service Test01_pry
port 9001
ip address 172.7.1.2
active
service Test01_sdy
port 9001
ip address 172.8.1.2
active
service Test01_ter
port 9001
ip address 172.9.1.2
active
service Test02_pry
port 9002
ip address 172.7.1.2
active
service Test02_sdy
port 9002
ip address 172.8.1.2
active
service Test02_ter
port 9002
ip address 172.9.1.2
active
service Test03_pry
port 9003
ip address 172.7.1.2
active

the limit is actually 256 keepalives of one type [in this case icmp as the default].
http://www.cisco.com/univercd/cc/td/doc/product/webscale/css/css_610/bsccfggd/services.htm#wp1026607
But there a limit of 64 concurrent icmp keepalive.
It means you have to adjust the keepalive frequency to avoid having more than 64 keepalive firing at the same time.
The CSS11500 can support more keepalives.
The limit is increase to 2048.
