SNMP Support for PFC and Buffer Statistics Tracking

Buffer Statistics Tracking (BST) feature provides a mechanism to aid in Resource Monitoring and Tuning
of Buffer Allocation. The support for Max Use Count mode in Buffer Statistics is introduced in Dell
Networking OS 9.3(0.). 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 flow 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.
The SNMP support for monitoring PFC and BST counters and statistics is introduced in Dell Networking
OS 9.3(0.1). The enhancement is made on F10-FPSTATS MIB with additional tables to display the PFC and
BST counters and statistics.
The following new tables are added in F10-FPSTATS MIB in Dell Networking OS 9.3(0.1):
• fpEgrQBuffSnapshotTable
• fpIngPgBuffSnapshotTable
• fpStatsPerPgTable
• pfcPerPrioTable
fpEgrQBuffSnapsh This table fetches the BST statistics at Egress Port for the buffer used. This table
otTable displays the Snapshot of the Buffer cells used by Unicast and Multicast Data and
Control Queues.
fpIngPgBuffSnapsh This table fetches the BST statistics at the Ingress Port for the Shared Cells, and the
otTable 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.
fpStatsPerPgTable This table fetches the Allocated Min cells, Shared cells, and Headroom cells per
Priority Group, the mode in which the buffer cells are allocated — Static or
Dynamic and the Used Min Cells, Shared cells and Headroom cells per Priority
Group. The table fetches a value of 0 if the mode of allocation is Static and a value
of 1 if the mode of allocation is Dynamic. This table lists thestack-unit number, port
number and priority group number.
