The device architecture uses a TCAM (Ternary Content Addressable Memory) to
support packet actions in wire speed.
TCAM holds the rules produced by applications, such as ACLs (Access Control
Lists), Quality of Service (QoS), IP Routing and user-created rules. The maximum
number of TCAM rules that can be allocated by all applications on the device is
2048 for Sx500 devices and 3096 for SG500X/ESW2-550X devices.
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 following fields are displayed for SG500X devices and for Sx500 devices in
Layer 3 system mode and when the device is part of a stack (per unit):
•

displayed when the device is in standalone mode.
•
