Enabling and viewing hardware usage statistics for an ACL
The number of configured ACL rules can affect the rate at which hardware resources are used. You
can use the show access-list hw-usage on command to enable hardware usage statistics, followed
by the show access-list <access-list-id> command to determine the hardware usage for an ACL. To
gain more hardware resources, you can modify the ACL rules so that it uses less hardware
resource.
To enable and view hardware usage statistics, enter commands such as the following:
PowerConnect# show access-list hw-usage on
PowerConnect# show access-list 100
Extended IP access list 100 (hw usage : 2)
deny ip any any (hw usage : 1
Syntax: show access-list hw-usage on
Syntax: show access-list <access-list-id>
where <access-list-id> is a valid ACL name or number.
Displaying ACL information
To display the number of Layer 4 CAM entries used by each ACL, enter the following command.
Syntax: show access-list <ACL-num> | <ACL-name> | all
The Rule cam use field lists the number of CAM entries used by the ACL or entry. The number of
CAM entries listed for the ACL itself is the total of the CAM entries used by the ACL entries.
For flow-based ACLs, the Total flows and Flows fields list the number of Layer 4 session table flows
in use for the ACL.
The Total packets and Packets fields apply only to flow-based ACLs.
Troubleshooting ACLs
Use the following methods to troubleshoot ACLs:
• To display the number of Layer 4 CAM entries being used by each ACL, enter the show
access-list <ACL-num> | <ACL-name> | all command. Refer to “Displaying ACL information”
on page 392.
