Cisco CSS – Configuring a Sorry Server

A sorry server provides HA (Primary/Secondary) based balancing for your backend servers. This allows traffic to only route to the sorry server in the event of the primary service becoming unreachable.

Below details the configuration. This example sets server 1 as the primary server and server 2 as the secondary server.

Configure Services

service server1                  
  ip address
  keepalive type tcp
  port 80

service server2              
  ip address                    
  keepalive type tcp
  port 80

Configure Content Rules


content vip-[public-ip]-80
    vip address
    protocol tcp
    add service server1
    primarySorryServer server2
