Description
Use this command to apply a specific CPU protection policy to the associated SAP, SDP or template.
If the mac-monitoring keyword is given then per MAC rate limiting should be performed, using the
per-source-rate from the associated cpu-protection policy.
If no CPU-protection policy is assigned to a SAP, then a default policy is used to limit the overall-rate
according to the default policy. The default policy is policy number 254 for access interfaces, 255 for
network interfaces.
The no form of the command reverts to the default values.
Default
cpu-protection 254 (for access interfaces)
cpu-protection 255 (for network interfaces)
The configuration of no cpu-protection returns the SAP/SDP/template to the default policies as
shown above.
Parameters
mac-monitoring — Enables per SAP + source MAC address rate limiting using the per-source-rate
from the associated cpu-protection policy.
eth-cfm-monitoring — Enables the Ethernet Connectivity Fault Management cpu-protection
extensions on the associated SAP/SDP/template.
aggregate — applies the rate limit to the sum of the per-peer packet rates.
car — (Committed Access Rate) Ignores Eth-CFM packets when enforcing overall-rate.
