rlCdpValidateMandatoryTlvs
Module: CISCOSB-CDP-MIB
OID (symbolic): CISCOSB-CDP-MIB::rlCdpValidateMandatoryTlvs
OID (numeric): 1.3.6.1.4.1.9.6.1.101.137.18
Node type: OBJECT-TYPE
Type: TruthValue
Access: read-write
Description: By setting the MIB to true all mandatory TLVs 0x0001-0x0006 will be validated. Incoming CDP frames without any of the TLVs will be dropped. A value of false indicates that only the Device ID TLV (0x0001) is mandatory. Frames containing Device ID TLV will be processed, regardless of whether other TLVs are present or not.
What is rlCdpValidateMandatoryTlvs?
This read-write TruthValue controls how strictly the device validates mandatory CDP TLVs 0x0001-0x0006 on incoming frames: true drops any frame missing one of those TLVs, while false only requires the Device ID TLV (0x0001) to be present. An admin sets it to balance strict CDP compliance checking against interoperability with neighbors that send incomplete TLV sets. For example, an admin having trouble discovering a third-party device via CDP might set this object to false so frames are accepted as long as they include at least a Device ID.
