What Is A3Com-Llc-r1-MIB?

A3Com-Llc-r1-MIB is a vendor MIB for 3Com network equipment that manages IEEE 802.2 Logical Link Control (LLC) layer configuration and statistics, a sublayer used in bridged/token-ring and other legacy LAN environments to multiplex protocols above the MAC layer. It exposes per-port LLC administrative parameters such as maximum SAPs, maximum connections, maximum PDU size, retransmission counts, and various protocol timers (acknowledgment, P-bit, reject). This is primarily a configuration and protocol-tuning MIB rather than a fault/hardware-health MIB, though excessive retransmit counts or timer misconfiguration surfaced through it can indicate a degraded link needing attention. It relies on the IEEE 802.2 LLC standard for its object semantics and sits within 3Com's bridger/router MIB tree. It is deployed on legacy 3Com bridges/routers that support LLC2-based connection-oriented data link services. Engineers can download the A3Com-Llc-r1-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in A3Com-Llc-r1-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 walk llcPortAdminTable (llcPortAdminEntry, indexed by llcPortAdminName) to review llcPortAdminMaxSaps and llcPortAdminMaxCcs, confirming a port is configured with enough service access points and connections for the attached protocol stacks. Reviewing llcPortAdminMaxRetransmits alongside llcPortAdminAckTimer and llcPortAdminRejTimer helps diagnose a port experiencing repeated LLC-level retransmissions, which points to an unreliable underlying link.

What Can Be Monitored

LLC max SAPs configured
max connections configured
