The switch architecture uses a TCAM (Ternary Content Addressable Memory) to
support an extensive data search in a short period of time.
TCAM holds the rules produced by other processes, such as ACLs (Access
Control Lists) or QoS. The maximum number of TCAM rules that can be allocated
by all processes is 512.
Some processes 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 opens, displaying the percentage of TCAM utilization in
the system.
This page displays TCAM Utilization, the percentage of TCAM resources used.
The TCAM Rules Per Process table lists all processes that can allocate TCAM
rules. Each process has its specific allocation policy.
