Category: Network Interfaces, Vendor: 3Com

Description: Monitors the 3Com AUDL (Asymmetric Universal Data Link) protocol, providing link-state and performance counters.

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 A3COM-AUDL-R1-MIB?

A3COM-AUDL-R1-MIB is a legacy vendor-specific MIB from 3Com covering AUDL (Asymmetric Universal Data Link), a proprietary WAN/link-layer protocol used on older 3Com routers and access devices. It exposes link-state and performance-counter style objects for AUDL-encapsulated links, such as link up/down status and traffic/error counters at the protocol layer. As a link-layer status/performance MIB it is used to monitor whether an AUDL link is currently operational and to track its throughput and error rates as an indicator of physical or line-quality problems, complementing standard ifTable interface status. It is a 3Com-specific extension typically used alongside the standard IF-MIB/RFC1213-MIB for full interface visibility, since AUDL details are not represented in standards-track MIBs. Deployment context is legacy 3Com WAN routers or access concentrators using the AUDL link protocol, now largely of historical/archival interest. Engineers can download the A3COM-AUDL-R1-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in A3COM-AUDL-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

No sample objects were provided for this module, so a specific object-level polling scenario cannot be grounded in real names; based on the short description, a monitoring station would poll per-link state and performance counters exposed under an AUDL link table to detect a link transitioning from up to down or a spike in associated error/performance counters. Confirming exact object names would require the underlying MIB source.

What Can Be Monitored

AUDL link operational state
AUDL link performance counters

OIDs

OID symbolic	OID numeric	Type	Access	Description
a3Com	1.3.6.1.4.1.43
brouterMIB	1.3.6.1.4.1.43.2
a3ComAuditLog	1.3.6.1.4.1.43.2.29
a3ComAudlControl	1.3.6.1.4.1.43.2.29.1
INT a3ComAudlControlAuditTrail	1.3.6.1.4.1.43.2.29.1.1	INTEGER	read-write	This parameter enables/disables the log message AuditTrail category which logs the AuditTrail messages. A default value of 2 means no AuditTrail.
INT a3ComAudlControlConfig	1.3.6.1.4.1.43.2.29.1.2	INTEGER	read-write	This parameter enables/disables the log message COnfig category which logs the SET/SETD/ADD/DELETE commands and other commands such as SysPassWord, SU, Login, Listen etc. The default value of 2 means no COnfig.
INT a3ComAudlControlMessages	1.3.6.1.4.1.43.2.29.1.3	INTEGER	read-write	This parameter enables/disables the log message MEssages category which log System Message and Dial History. The default value of 2 means no MEssages.
INT a3ComAudlControlSecurity	1.3.6.1.4.1.43.2.29.1.4	INTEGER	read-write	This parameter enables/disables the log message SEcurity category which logs faulted set privilege, failed login and invalid community string. The default 2 means no SEcurity.
a3ComAudlConfig	1.3.6.1.4.1.43.2.29.2
IP a3ComAudlLogServerAddr	1.3.6.1.4.1.43.2.29.2.1	IpAddress	read-write	This is the IP address of a log server which has syslog daemon active with proper syslog configuration.
INT a3ComAudlPriorityLevel	1.3.6.1.4.1.43.2.29.2.2	INTEGER	read-write	The level is used with facility to format a priority which used as a tag in log message before sending it to syslog daemon. It also controls the log sending operation, a log message with higher Level will be be sent together with what has been in Audit Log buffer, to a LogServerAddr immediately.
INT a3ComAudlMaxLog	1.3.6.1.4.1.43.2.29.2.3	INTEGER	read-write	It decides the maximum number of log commands/messages could accumulate in Audit Log buffer before sending to a LogServerAddr. Value 1 means send each log without buffering.
INT a3ComAudlIdleTime	1.3.6.1.4.1.43.2.29.2.4	INTEGER	read-write	This controls the idle time in minute till sending Audit log buffer if it has data. Value of 0 means this idle time is disabled.
