Hardware Resource Utilization
This page displays resources used by the system, such as ACLs (Access Control Lists) and
Quality of Service (QoS). The Router TCAM holds the rules for VLAN mapping and policy-
based routing rules for IPv4 and IPv6.
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 hardware resource utilization, click Status and Statistics > Hardware Resource
Utilization.

• Unit No—Unit in stack for which TCAM utilization appears. This is not displayed
