ignore-hostcar

Function

The ignore-hostcar acl command configures host CAR and VLAN-Host-CAR not to apply to packets matching a specified ACL rule.

This command is supported only on the NetEngine 8000 F1A.

Usage Guidelines

Usage Scenario

When you do not want packets sent from the user side to the CPU to be limited, run the ignore-hostcar acl command to prevent host CAR and VLAN-Host-CAR from applying to the packets matching a specified ACL rule.

Precautions

When the action of an ACL rule is deny, the packets matching the ACL rule are not discarded and are still sent to the CPU.

In VS mode, this command is supported only by the admin VS.
