diffServClassifierNextFree
Module: DIFF-SERV-MIB
OID (symbolic): DIFF-SERV-MIB::diffServClassifierNextFree
OID (numeric): 1.3.6.1.2.1.12345.1.1
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-only
Description: This object yields a value when read that is currently-unused for a diffServClassifierId instance. If a configuring system attempts to create a new row in the diffServClassifierTable using this value, that operation will fail if the value has, in the meantime, been used to create another row that is currently valid.
What is diffServClassifierNextFree?
Reading this object returns an unused ID suitable for creating a new row in the classifier table, saving the management station from having to scan existing entries to find a free index. It's a convenience counter rather than a live traffic statistic. If two managers grab the same value before either commits a row, the second row-creation attempt will simply fail.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.12345.1.1 snmpwalk -v2c -c public <target> DIFF-SERV-MIB::diffServClassifierNextFree
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.2.1.12345.1.1.1 snmpget -v2c -c public <target> DIFF-SERV-MIB::diffServClassifierNextFree.1
