SNMP Support for PFC and Buer Statistics Tracking
Buer Statistics Tracking (BST) feature provides a mechanism to aid in Resource Monitoring and Tuning of Buer Allocation. The Max Use
Count mode provides the maximum value of the counters accumulated over a period of time.
Priority Flow Control (PFC) provides a link level ow control mechanism, which is controlled independently for each frame priority. The goal
of this mechanism is to ensure zero loss under congestion in DCB networks.
Dell EMC Networking OS provides SNMP support for monitoring PFC and BST counters, and statistics. The enhancement is made on
DELL-NETWORKING-FPSTATS-MIB with additional tables to display the PFC and BST counters and statistics.
The following tables are available in DELL-NETWORKING-FPSTATS-MIB:
• dellNetFpEgrQBuSnapshotTable
• dellNetFpIngPgBuSnapshotTable
• dellNetFpStatsPerPgTable
• dellNetPfcPerPrioTable
dellNetFpEgrQBuS
napshotTable
This table fetches the BST statistics at Egress Port for the buer used. This table displays the Snapshot of the
Buer cells used by Unicast and Multicast Data and Control Queues.
dellNetFpIngPgBuS
napshotTable
This table fetches the BST statistics at the Ingress Port for the Shared Cells, and the Headroom cells used per
Priority Group. The snapshot of the Ingress Shared cells used and the Ingress Headroom cells used per Priority
Group, when PFC is enabled, display in this table. This table lists the stack-unit index, port number and the priority
group number.
