dellNetFpIfIngHeadroomCells
Module: DELL-NETWORKING-FPSTATS-MIB
OID (symbolic): DELL-NETWORKING-FPSTATS-MIB::dellNetFpIfIngHeadroomCells
OID (numeric): 1.3.6.1.4.1.6027.3.27.1.17.1.3
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: Headroom cell count per priority group.
What is dellNetFpIfIngHeadroomCells?
This read-only value is a point-in-time snapshot of how many headroom buffer cells -- the reserved margin that absorbs in-flight traffic during the round-trip time of a Priority Flow Control pause -- are currently in use on this specific interface's ingress priority group. An admin watching this during PFC/lossless-Ethernet tuning (e.g. for iSCSI or RoCE traffic) uses it to confirm headroom is sized correctly: if it regularly approaches its configured limit, packets could be dropped despite PFC being enabled.
