profile tcam

Optimizes hardware resources, by specifying a ternary content-addressable memory (TCAM) profile that meets your needs.

Syntax

profile tcam { app-telemetry | border-routing | default | layer2-ratelimit | multicast-profile | vxlan-visibility }

no profile tcam

The default TCAM profile is enabled.

app-telemetry: Optimizes resources for application telemetry. MCT is supported.
border-routing: Optimizes resources for border routing and BGP Flowspec features.
default: Optimizes resources with basic support for all applications. MCT is supported.
layer2-ratelimit: Optimizes resources for Layer 2 ACL egress rate-limiting and related applications.
multicast-profile: (Not currently supported) Optimizes resources for L2/3 IPv6 multicast.
vxlan-visibility: Optimizes resources for VXLAN transit visibility and GRE.

Hardware configuration mode

Important

This is a disruptive command. For the last update of the profile configuration to take effect, reboot the device by entering reload system.

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".

The border-routing profile (but not the default TCAM profile) supports the following BGP flowspec match criteria:

To restore the default profile, enter the no form of this command.

For devices based on the DNX chipset-family, the following table displays scale limits by technology 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.

The following example optimizes TCAM resources for applications without MCT support.

device# configure terminal
device(config)# hardware
device(config-hardware)# profile tcam vxlan-visibility
