Chapter 23 Configuring QoS

Monitoring QoS

Viewing QoS Shaping Statistics

To view statistics for service policies implementing the shape command, use the show service-policycommand with the shape keyword:

ciscoasa# show service-policy shape

The following is sample output for the show service-policy shape command:

ciscoasa# show service-policy shape Interface outside

Service-policy: shape Class-map: class-default

Queueing

queue limit 64 packets

(queue depth/total drops/no-buffer drops) 0/0/0 (pkts output/bytes output) 0/0

shape (average) cir 2000000, bc 8000, be 8000

The following is sample output of the show service policy shape command, which includes service policies that include the shape command and the service-policycommand that calls the hierarchical priority policy and the related statistics:

ciscoasa# show service-policy shape

Interface outside:

Service-policy: shape

Class-map: class-default

Queueing

queue limit 64 packets

(queue depth/total drops/no-buffer drops) 0/0/0 (pkts output/bytes output) 0/0

shape (average) cir 2000000, bc 16000, be 16000

Service-policy: voip

Class-map: voip

Queueing

queue limit 64 packets

(queue depth/total drops/no-buffer drops) 0/0/0 (pkts output/bytes output) 0/0

Class-map: class-default

queue limit 64 packets

(queue depth/total drops/no-buffer drops) 0/0/0 (pkts output/bytes output) 0/0

Viewing QoS Standard Priority Queue Statistics

To display the priority-queue statistics for an interface, use the show priority-queue statistics command in privileged EXEC mode. The results show the statistics for both the best-effort (BE) queue and the low-latency queue (LLQ). The following example shows the use of the show priority-queue statistics command for the interface named test, and the command output.

ciscoasa# show priority-queue statistics test
