The dynamic allocation of Ternary Content Addressable Memory (TCAM) space in ACX
Series efficiently allocates the available TCAM resources for various filter applications.
In the dynamic TCAM model, various filter applications (such as inet-firewall,
bridge-firewall, cfm-filters, etc.) can optimally utilize the available TCAM resources as
and when required. Dynamic TCAM resource allocation is usage driven and is dynamically
allocated for filter applications on a need basis. When a filter application no longer uses
the TCAM space, the resource is freed and available for use by other applications. This
dynamic TCAM model caters to higher scale of TCAM resource utilization based on
application's demand. You can use the show and clear commands to monitor and
troubleshoot dynamic TCAM resource usage in ACX Series routers.
NOTE: Applications using the TCAM resource is termed tcam-app in this
document.

TCAM resources in ACX Series routers
