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
