The configuration below defines a Layer 3 and a Layer 7 class-map.

•

The Layer 3 class-map is used to define a Virtual IP and the allowed traffic port. This class
map gets applied to the Layer 3/4 policy-map. Traffic sent to the virtual IP is directed by the
ACE server to real media servers based on the load balancing policy.

•

The Layer 7 class-map is used to filter traffic based on the URL pattern specified. This
class-map is associated with a Layer 7 policy-map, which contains information about which
servers to load balance.

When traffic entering the ACE server matches the class-map L3_Media_Server_VIP, the ACE
server applies the actions specified in Media_Server_L7SLB, which is defined below.

class-map match-all L3_Media_Server_VIP

   2 match virtual-address 10.1.1.3 tcp eq www

class-map type http loadbalance match-all L7_HTTP_CLASS

   2 match http url .*

Note: In the code below, the layer 7 Class map gets associated with the layer 7 policy map.

ASR/TTS Servers

The probe below is used to determine whether the MRCP ASR/ TTS Server is up. The ACE
server makes a connection to the MRCP port to validate that the ASR/TTS server is running.
In the configuration below, a TCP probe is used. The probe waits for the configured 3 seconds
to receive information from the server. The ASR/TTS service is considered down if the ACE
server is unable to connect to port 554 for MRCP traffic.
