Viewing TCAM Utilization
The switch architecture uses a TCAM (Ternary Content Addressable Memory) to
support extensive data search in a short period of time.
TCAM holds the rules produced by other applications, such as ACLs (Access
Control Lists) and Quality of Service (QoS).
The maximum number of TCAM rules that can be allocated by all applications on
the SG500X device is 3072 and the Sx500 device is 2048.
Some applications allocate rules upon their initiation. Additionally, processes that
initialize during system boot use some of their rules during the startup process.

specific allocation policy.
