Description
Traffic destined for the CPU interfaces;
not actually a VLAN.
Increments with VLAN_MASK_TO_NULL.
Increments for an access list matching the frame.
If an ACL is not applied, this will increment if a large
amount of CPU-bound traffic is being received, and the
rate limit in the hardware is enabled to protect NX-OS
from Denial of Service.
