AT-LOOPPROTECT-MIB

Description: Monitors and controls loop protection mechanisms that detect and disable ports with forwarding loops on Allied Telesis switches.

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.

AT-LOOPPROTECT-MIB is an Allied Telesis enterprise MIB for the Loop Protection feature on Allied Telesis switches, which detects Ethernet forwarding loops on individual ports and automatically disables them to prevent broadcast storms. Although no sample objects were supplied, based on its stated purpose it would expose per-port loop-detection state, enable/disable configuration, and likely a shutdown/disabled status flag along with possible trap notifications for loop events. Its monitoring value centers on fault detection at the port level: administrators would use it to see which ports have detected a loop and been automatically shut down, letting them quickly locate a misbehaving cable, hub, or misconfigured switch causing the loop. It likely depends on the standard IF-MIB ifIndex convention to identify affected ports, consistent with typical Allied Telesis per-port feature MIBs. It is typically deployed on Allied Telesis managed switches in enterprise or campus LANs where loop protection is enabled to guard against accidental physical loops, making AT-LOOPPROTECT-MIB SNMP monitoring a standard part of quickly locating a misbehaving port causing a loop.

Since no sample objects were provided, a plausible scenario (not directly evidenced) is: an operator would poll a per-port loop-protection status table indexed by ifIndex to see which ports are enabled for loop protection and whether any have transitioned to a loop-detected/disabled state, then physically inspect the cabling on the flagged port to resolve the loop.
