When the ACL logging feature is enabled, an informational SYSLOG message is
generated for packets that match ACL rules.
To view the interfaces on which packets were forward or rejected based on ACLs:
Click Status and Statistics > ACL.
Select the Refresh Rate (time period in seconds) that passes before the page is
refreshed. A new group of interfaces is created for each time period.
The following information is displayed:
• Global Trapped Packet Counter—Number of packets trapped globally due
to lack of resources.
• Trapped Packets - Port/LAG Based—The interfaces on which packets were
forwarded or rejected based on ACL rules.
• Trapped Packets - VLAN Based—The VLANs on which packets were
forwarded or rejected based on ACL rules.
To manage statistics counters:
• Click Clear Counters to clear the counters of all interfaces.
TCAM holds the rules produced by applications, such as ACLs (Access Control
Lists), Quality of Service (QoS), while Router TCAM holds the rules for IP Routing
and user-created rules.
Some applications allocate rules upon their initiation. Additionally, processes that
initialize during system boot use some of their rules during the startup process.
To view TCAM utilization, click Status and Statistics > TCAM Utilization.
The TCAM Utilization page shows the following fields:
• Unit No—Unit in stack for which TCAM utilization appears. This is not
displayed when the device is in not part of a stack.
