Viewing TCAM Utilization
The switch architecture uses a Ternary Content Addressable Memory (TCAM) to
support packet actions in wire speed. TCAM holds the rules produced by
applications (such as ACL and QoS) and the system-created rules.
Only system application allocates rules upon its initiation.
To view TCAM utilization, click Status and Statistics > TCAM Utilization.
The following fields are displayed:
• Maximum TCAM Entries—Maximum TCAM entries available.
• In Use—Number of TCAM entries that are currently using.
