along with a port-pipe number,
then the keyword counters to display the counters on the
selected port-pipe. The range is 0 to 0.
buffer-info buffer-info Displays total buffer information for a group,
where
x can be one of the following:
• All - Displays ingress and egress device, port, and queue
snapshots
• Port {id |all} Displays both ingress and egress port-level
snapshot
• Port ingress {id |all} Displays ingress port-level snapshot
• Port egress {id |all) Displays egress port-level snapshot
• Port {id |all} queue {all} - egress queue-level snapshot for
both unicast and multicast packets
• Port {id |all} queue ucast {id | all} - egress queue-level
snapshot for unicast packets only
• Port {id |all} queue mcast {id | all} - egress queue-level
snapshot for multicast packets only
• Port {id |all} prio-group {id | all} - ingress priority-group
level snapshot

Usage
Information
The following information is displayed based on the buffer-info type, such as
device-level details, port-level counters, queue-based snapshots, or priority group-
level snapshot in the egress and ingress direction of traffic:
• Device-ingress – Displays total buffer accounting usage for the unit.
• Device-egress –Display total buffer usage for the unit, total multicast buffer
usage for the unit and also on per-service-pool basis. Counters will be
displayed for the 2 service-pools – one for normal traffic and other for DCB
traffic.
• Port-ingress – Displays the total buffer accounting usage for the ingress port.
• Port-egress – Displays the total unicast buffer usage, total multicast buffer
usage separately for the egress port.
• Port-Queue ucast/mcast – Displays the total unicast/multicast buffer usage on
per-port per-queue basis. For CPU port, counters for queues 0 – 11 will be
displayed and there is no differentiation between unicast and multicast queues.
