Configuring QoS TCAM Carving
To keep all modules synchronized, you must reload all line card modules or enter the copy running-config
Note
startup-config command and the reload command to reload the device. Multiple TCAM region
configurations require only a single reload. You can wait until you complete all of your TCAM region
configurations before you reload the device.
If you exceed the 4K ingress limit for all TCAM regions when you configure a TCAM region, the following
message appears:
ERROR: Aggregate TCAM region configuration exceeded the available Ingress TCAM space.
Please re-configure.
If TCAM for a particular feature is not configured and you try to apply a feature that requires TCAM carving,
the following message appears:
ERROR: Module x returned status: TCAM region is not configured. Please configure TCAM
region and retry the command.
