SNMP properties

Value type: Counter
Maximum access defined by MIB: read-only
Status in MIB: current

Interpreting this counter

A counter is cumulative. To estimate a rate, subtract two readings and divide by the elapsed time; use the units stated in the MIB.

Counter values can wrap or reset. A decrease alone does not distinguish a wrap from a reset, and multiple wraps between readings cannot be recovered reliably. Check the device's discontinuity indicators when available.

Published counter width: 32 bits. SMIv2: Counter32 · Counter64

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 DLINK-MSTP-MIB, the row index swMSTPInstId is declared as INTEGER. A non-negative index value is encoded as one numeric subidentifier. An instance has the form .1.3.6.1.4.1.171.13.15.2.3.1.22.<swMSTPInstId>. Use an index value actually present on the device and permitted by its MIB. Other definitions can differ.

snmpwalk [connection options] DEVICE .1.3.6.1.4.1.171.13.15.2.3.1.22

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.
