Using the Debug Facility

The debug facility enables you to display all packets going to and from the controller CPU. You can

enable it for received packets, transmitted packets, or both. By default, all packets received by the debug

facility are displayed. However, you can define access control lists (ACLs) to filter packets before they

are displayed. Packets not passing the ACLs are discarded without being displayed.

Each ACL includes an action (permit, deny, or disable) and one or more fields that can be used to match

the packet. The debug facility provides ACLs that operate at the following levels and on the following

values:

• Driver ACL

–

NPU encapsulation type

–

Port

• Ethernet header ACL

–

Destination address
