Hardware Resource Utilization

This page displays the resources used by the device, such as Access Control Lists (ACL) and Quality of Service (QoS). Some applications allocate rules upon their initiation.

The count of each item may differ from different Models due to system design. Also, because of ASIC characteristics, it’s possible to show a "Lack of HW resources" when binding an Advance QoS service policy or User-defined ACL but this page shows enough TCAM resources.

To view the hardware resource utilization, click Status and Statistics > Hardware Resource Utilization.
