wfSipL2SequenceNumberErrors
Module: Wellfleet-SIP-MIB
OID (symbolic): Wellfleet-SIP-MIB::wfSipL2SequenceNumberErrors
OID (numeric): 1.3.6.1.4.1.18.3.4.14.1.1.6
Node type: OBJECT-TYPE
Type: Counter
Access: read-only
Description: total SIP L2 PDUs with unexpected sequence numbers
What is wfSipL2SequenceNumberErrors?
This counter increments each time a SIP Level-2 PDU arrives with an unexpected sequence number, meaning cells were lost, duplicated, or reordered in transit. Admins watch it to catch reassembly problems that would otherwise silently corrupt higher-layer SMDS traffic. For example, a burst of wfSipL2SequenceNumberErrors during peak hours could indicate the SNI is being oversubscribed and dropping cells.
