usdL2fSessionStatPayLostPackets

Module: Unisphere-Data-L2F-MIB

OID (symbolic): Unisphere-Data-L2F-MIB::usdL2fSessionStatPayLostPackets

OID (numeric): 1.3.6.1.4.1.4874.2.2.53.1.4.3.1.1.12

Node type: OBJECT-TYPE

Type: Unsigned32

Access: read-only

Description: When sequence numbers are enabled, this value represents the estimated number of payload packets lost, based on observed gaps in sequence numbers. This estimate is subject to correction (decrement) upon receipt of out-of-sequence packets that fill previously observed gaps.

What is usdL2fSessionStatPayLostPackets?

An estimate of payload packets lost on this session, derived from gaps observed in sequence numbers; the estimate is corrected downward if a later out-of-sequence packet fills a previously observed gap. It's used when sequencing is enabled to gauge real data loss on this session, as distinct from packets merely arriving out of order.
