The following information is displayed based on the buffer-info type, such as device-level details, 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
