lldpStatsRxPortTLVsUnrecognizedTotal
Module: LLDP-MIB
OID (symbolic): LLDP-MIB::lldpStatsRxPortTLVsUnrecognizedTotal
OID (numeric): 1.0.8802.1.1.2.1.2.7.1.6
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description:
The number of LLDP TLVs received on the given port that are not recognized by this LLDP agent on the indicated port.
An unrecognized TLV is referred to as the TLV whose type value is in the range of reserved TLV types (000 1001 - 111 1110) in Table 9.1 of IEEE Std 802.1AB-2005. An unrecognized TLV may be a basic management TLV from a later LLDP version.
What is lldpStatsRxPortTLVsUnrecognizedTotal?
This counter tracks the total number of LLDP Type-Length-Value (TLV) frames received on a port that were not recognized by the LLDP agent. Unrecognized TLVs use reserved type values or are from newer LLDP versions. Operators monitor this to ensure LLDP compatibility with neighboring devices and identify version mismatches.
