TCAM profiles

TCAM profiles enable you to optimize TCAM resources according to your system requirements.

Note

TCAM profiles other than default are supported only on devices based on the DNX chipset family. For a list of such devices, see "Supported Hardware".

TCAM is used by various forwarding applications. A TCAM profile supports a specified group of forwarding applications.

The following TCAM profiles are supported:

default: Optimizes resources with basic support for all applications. MCT is supported.
app-telemetry: Optimizes resources for application telemetry. MCT is supported.
border-routing: Optimizes resources for border routing and BGP Flowspec features.
cam-share: Enables TCAM sharing for security or policy-based routing (PBR) ACLs applied to multiple interfaces.
layer2-ratelimit: Optimizes resources for Layer 2 ACL egress rate-limiting and related applications.
(Not currently supported) multicast-profile: Optimizes resources for L2/3 IPv6 multicast.
vxlan-visibility: Optimizes resources for VXLAN transit visibility and GRE.

TCAM Profile Scaling (DNX Devices)

For devices based on the DNX chipset-family, the following table displays maximum TCAM entries by features and TCAM profile.

* For shared limits, the TCAM is filled using first-come first-served.

** DB is shared with L2 and L3 control protocol features.

NS = not supported.

RL = rate limiting.

BD = bridge domain.

Default TCAM Profile (XGS Devices)

For devices based on the XGS chipset-family, the following table displays maximum TCAM entries by features. The only TCAM profile supported is default.

* For shared limits, the TCAM is filled using first-come first-served.

** DB is shared with L2 ctrl protocol, L3 protocol, and so forth.

NS = not supported.

RL = rate limiting.

BD = bridge domain.
