Description: Extreme Networks MIB for SummitStack and stacking technology, managing stacked switch topology, roles, and inter-unit links.

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 EXTREME-STACKING-MIB?

EXTREME-STACKING-MIB is an Extreme Networks module for managing SummitStack and related stacking technology, covering the topology, member roles, and inter-unit links of a stack of Extreme switches operating as a single logical device. It exposes data about stack topology, which unit holds the master/backup role, and the health of inter-unit stacking links connecting the switches together. It supports monitoring both hardware status (stacking link connectivity, unit presence) and software/role status (master/backup election state) of a stacked switch system, important for detecting a split stack, a failed stacking link, or an unexpected role change. It likely depends on or complements the ENTITY-MIB and Extreme's own hardware MIB for full physical inventory of stack members. It is deployed wherever multiple Extreme switches are physically stacked and managed as a single logical switch for higher port density and resiliency. Engineers can download the EXTREME-STACKING-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in EXTREME-STACKING-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 specific object or table names were available in the source material for this MIB, so a concrete polling scenario referencing its own OIDs cannot be honestly constructed here. In practice, an administrator would typically poll such a stacking MIB to confirm each unit's stack role (master/backup/standby) and the operational state of inter-unit stacking links, but the specific object names could not be confirmed from available data.

How to Use in IPNetwork Monitor

Example using extremeStackMemberOperStatus OID:

Select an Extreme Networks SummitStack stackable switch as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type extremeStackMemberOperStatus into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. The operational status of the stack member. When the stack comes up, if there is a vector mismatch namely license mismatch or platform mismatch between the master and the member, the member remains in the mismatch state. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is an INTEGER-type OID, Value bounds is the most useful condition here — trigger an alert if the value is 'down' or 'mismatch', since 'mismatch' means a license or platform mismatch is keeping this member out of the stack. Click Finish to create the monitor; you can adjust any parameter later.
