SLE-RED-MIB

Description: Manages DASAN Networks SLE OLT redundancy configuration, failover groups, and switchover state.

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.

SLE-RED-MIB manages active/standby redundancy on DASAN Networks' SLE OLT broadband access platform, controlling failover groups and switchover state between redundant control or line cards. It belongs to the high-availability/system-resiliency category within fiber broadband access technology. Its monitoring emphasis is squarely on hardware/software resiliency status: which unit in a redundancy group is currently active versus standby, and whether a switchover has occurred, which is a key signal for detecting a card failure or unplanned failover event that could briefly disrupt subscriber service. It depends on the broader SLE OLT system/chassis MIB for card and slot context needed to identify redundancy group members. It is deployed on DASAN/Hanasoft OLT chassis configured with redundant control cards for high-availability broadband access service. Engineers can download the SLE-RED-MIB file directly to load it into their MIB browser.

An operator would poll the redundancy group's active/standby role for each card to confirm the expected unit is active, and watch for a switchover event indicating the previously active card failed or was manually taken offline. Tracking switchover history helps correlate a brief subscriber service interruption with a redundancy failover rather than a wider outage. An unexpected or repeated switchover between units would point to instability on the previously active control card warranting hardware inspection.
