Using this OID with SNMP

At least one MIB declaration places this object in a table row. A value belongs to a row instance; its suffix depends on the row's INDEX or AUGMENTS definition.

In SW-LAYER2-PORT-MANAGEMENT-MIB, the row index consists of these components in order:

  1. swL2PortCtrlUnitIndex (INTEGER): one numeric subidentifier for the non-negative value.
  2. swL2PortCtrlModuleIndex (INTEGER): one numeric subidentifier for the non-negative value.
  3. swL2PortCtrlIndex (INTEGER): one numeric subidentifier for the non-negative value.

An instance has the form .1.3.6.1.4.1.171.11.25.2.4.2.1.12.<swL2PortCtrlUnitIndex>.<swL2PortCtrlModuleIndex>.<swL2PortCtrlIndex>. Use values present on the device and permitted by its MIB. Other definitions can differ.

snmpwalk [connection options] DEVICE .1.3.6.1.4.1.171.11.25.2.4.2.1.12

Replace the placeholders with your connection and authentication options. Available permissions and device support can differ from the MIB.

Properties come from available MIB definitions. Actual device support and access can differ. See source records below for original files and qualifications.

The displayed source records contain one distinct definition. Compare its source records.
