Enables TCAM sharing for security or policy-based routing (PBR) ACLs that are applied to multiple interfaces.
By default, TCAM sharing is disabled.
Hardware configuration mode
TCAM sharing is supported on the Extreme 8820, SLX 9740, SLX 9640, and SLX 9540 devices only sharing all ports with the same ASIC.
TCAM sharing for security ACLs works as follows: TCAM resources are shared if a specific ACL is applied to multiple ports.
TCAM sharing for PBR ACLs works as follows: TCAM resources are shared if a specific ACL (included in one or more route maps) is applied to multiple ports.
When you change the TCAM profile type, also update cam sharing based on the limitation of the new profile. TCAM sharing is not supported for user-defined ACLs or for ACLs that are applied for rate limiting.
For the new setting to take effect, you need to run the copy running-config startup-config to reload the device. Run this command during a maintenance window so that the profile changes are activated without interrupting normal network services.
Use the no form of the command to disable TCAM sharing.
This example enables TCAM cam sharing for Layer 2 ingress ACL.
device(config)# hardware device(config-hardware)# profile tcam cam-share l2-ingress-acl **Warning: To activate the new profile config, please run 'copy running-config startup-config' followed by 'reload system'.This example disables TCAM cam sharing.
device(config)# hardware device(config-hardware)# no profile tcam cam-share **Warning: To activate the new profile config, please run 'copy running-config startup-config' followed by 'reload system'.
