Information
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
also on per-service-pool basis. Counters will be displayed for the 2 service-pools – one for normal
traffic and other for DCB traffic.
When the buffer-stats-snapshot is disabled, the following informational message is displayed when you
run the show command: %Info: Buffer-stats-snapshot feature is disabled.
