Viewing a classifier-based QoS configuration

Use the following show commands to display information about a classifier-based QoS configuration and statistics or resource usage on QoS policies.

Syntax:


show class ipv4 classname


show class ipv6 classname


show class config

ipv4 classname: Lists the statements that make up the IPv4 class identified by classname.
ipv6 classname: Lists the statements that make up the IPv6 class identified by classname.
config: Displays all classes, both IPv4 and IPv6, and lists the statements that make up each class.

Additional variants of the show class command provide information on classes that are members of policies that have been applied to ports or VLANs.

Syntax:


show policy policy-name


show policy config

policy-name: Lists the statements that make up the specified policy.
config: Displays the names of all policies defined for the switch and lists the statements that make up each policy.

Additional variants of the show policy command provide information on policies that have been applied to ports or VLANs.

Viewing show policy output for a QoS policy

switch(config)# show policy suspect-traffic
Statements for Policy "suspect-traffic"
  10 class ipv4 "http" action rate-limit kbps 2000 action priority 3
  20 class ipv4 "kazaa" action rate-limit kbps 1000 action priority 2
  30 class ipv4 "gnutella" action rate-limit kbps 1000 action priority 2

Syntax:


[show | clear] statistics policy policy-name port port-num 
 [show | clear] statistics policy policy-name vlan vid in

show: Displays the statistics for a specified policy applied to a specified port or VLAN.
clear: Clears statistics for the specified policy and port or VLAN.
policy-name: Specifies the name of the policy.
port-num: Specifies the number of the port on which the policy is applied (single port only, not a range).
vid: Specifies the number or name of the vlan on which the policy is applied. VLAN ID numbers range from 1 to 4094.
in: Specifies that statistics are shown for inbound traffic only.

Viewing show statistics policy output for a QoS policy

Syntax:


show policy resources

Displays the number of hardware resources (rules, meters, and application port ranges) used by classifier-based QoS policies that are currently applied to interfaces on the switch, mirroring policies, and other software features.

NOTE:

The information displayed is the same as the output of show qos resources and show access-list resources commands. For a detailed explanation of the information displayed with the show [qos | access-list | policy] resources command, see the ArubaOS-Switch Management and Configuration Guide for your switch.

Viewing show policy resources output for all currently configured QoS policies

switch(config)# show policy resources

 0 of 8 Policy Engine management resources used.

 Key:
 ACL = Access Control Lists
 QoS = Device & Application Port Priority, QoS Policies, ICMP rate limits
 IDM = Identity Driven Management
 VT  = Virus Throttling blocks
 Mirror = Mirror Policies, Remote Intelligent Mirror endpoints
 PBR = Policy Based Routing Policies
 Other = Management VLAN, DHCP Snooping, ARP Protection, Jumbo IP-MTU,
         Transparent Mode.

 Resource usage includes resources actually in use, or reserved for future
 use by the listed feature.  Internal dedicated-purpose resources, such as
 port bandwidth limits or VLAN QoS priority, are not included.
