Description: Manages Cisco Small Business LLDP (Link Layer Discovery Protocol) neighbor discovery and TLV configuration.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is CISCOSB-LLDP-MIB?

CISCOSB-LLDP-MIB is a Cisco Small Business private MIB that extends standard LLDP (Link Layer Discovery Protocol) with vendor-specific configuration options, including auto-advertisement of management addresses and LLDP-MED settings. It exposes objects for enabling/disabling LLDP globally, per-port advertisement status, discovery/duplex mode, and tables of locally advertised management address information. Its monitoring value lies in neighbor discovery and topology/configuration status—confirming LLDP is active on the right ports and that management address advertisements are correctly propagating, which helps detect cabling/topology misconfigurations. It is a Cisco extension layered on top of the standard IEEE 802.1AB LLDP MIB (LLDP-MIB) and Cisco's LLDP-MED handling. It is deployed on Cisco Small Business switches to support automatic network topology discovery for management tools like FindIT. Engineers can download the CISCOSB-LLDP-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCOSB-LLDP-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Monitoring Examples

An administrator would check rlLldpEnabled and rlLldpAutoAdvPortsStatus to confirm LLDP and address auto-advertisement are active on expected ports, then browse rlLldpAutoAdvLocPortManAddrTable/rlLldpAutoAdvLocPortManAddrEntry (indexed by rlLldpAutoAdvLocPortNum) to see which management addresses are being advertised out each port. If a port that should be advertising an address shows rlLldpAutoAdvManAddrNone instead, it indicates a misconfiguration preventing neighbor discovery tools from finding that device. rlLldpDuMode and rlLldpClearRx help verify the discovery/reception mode and reset stale neighbor data.

What Can Be Monitored

LLDP enable/disable status
per-port LLDP advertisement status

NTF rlLldpTLVsTxOverloadingStateExitTrap	1.3.6.1.4.1.9.6.1.101.0.210			Informational trap indicating that the port is no longer in the overloading state..
rlLldp	1.3.6.1.4.1.9.6.1.101.110			This private MIB module adds MIBs to LLDP (Link Layer Discovery Protocol).
rlLldpObjects	1.3.6.1.4.1.9.6.1.101.110.1
rlLldpConfig	1.3.6.1.4.1.9.6.1.101.110.1.1
T/F rlLldpEnabled	1.3.6.1.4.1.9.6.1.101.110.1.1.1	TruthValue	read-write	Setting this variable to 'true' will globally enable the LLDP feature (both transmit and receive functionalities). Setting this variable to 'false' will globally disable the LLDP feature. Thus, the administratively desired status of a local port is determined by both this variable and the MIB lldpPortConfigAdminStatus.

Clears the Rx information about the remote agents accordingly to the specified PortList. The default value for rlLldpClearRx object is an empty binary string, which means no ports are specified to be cleared from the Rx Info. This object behaviors as an event (write-only) than reading this object always results in an Empty Port List of length zero.

The management address, automatically advertised from associated 'rlLldpAutoAdvLocPortNum'local port is assigned to mentioned 'rlLldpAutoAdvManAddrOwnerIfId' interface. In case of 0 the management address is automatically calculated without care to the ifIndex it was defined on.
T/F rlLldpAutoAdvManAddrNone	1.3.6.1.4.1.9.6.1.101.110.1.1.4.1.3	TruthValue	read-write	A value of 'true' indicates that the any management address hasn't advertised by the local port. Moreover, the configuration of automatic management address advertisment is disabled. A value of 'false' indicates that the configuration of automatic management address advertisment is enabled.
