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 SWITCH, the row index udldIfIndex is declared as Integer32. A non-negative index value is encoded as one numeric subidentifier. An instance has the form .1.3.6.1.4.1.27975.76.4.1.4.<udldIfIndex>. Use an index value actually present on the device and permitted by its MIB. Other definitions can differ.

Published row index: udldIfIndex.

snmpwalk [connection options] DEVICE .1.3.6.1.4.1.27975.76.4.1.4

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.
