frame notifies section Contains the bitmap that results from combining the maps and masks from
the bitmaps section. If SPAN is configured, there might be additional
bitmaps displayed.
Egress q <nn> section There is an egress section for each separate destination port. The output is
varied, but the important information is in the line containing the name of
an output interface, output VLAN ID, and rewritten destination MAC
address for the frame. If the output interface is a trunk port that needs to
send multiple copies of the frame on different VLANs (for example, for IP
multicast frames), several lines might contain the same output interface
name, but a different output VLANs.
If output security ACLs are present, it is possible that one or more of these
egress q sections will not contain a line listing an output port. This
happens when the output ACL denies the packet.
Cpu q <nn> <name>
section
When the CPU is one of the destinations for a packet, this section appears,
followed by a queue name. This name should correspond to one of the
queue names in the output from the show controllers cpu-interface
privileged EXEC command, where statistics appear for the number of
packets received at each queue.
