diffServSixTupleClfrNextFree

Module: DIFF-SERV-MIB

OID (symbolic): DIFF-SERV-MIB::diffServSixTupleClfrNextFree

OID (numeric): 1.3.6.1.2.1.12345.1.2

Node type: OBJECT-TYPE

Type: Unsigned32

Access: read-only

Description: This object yields a value when read that is currently-unused for a diffServSixTupleClfrId instance. If a configuring system attempts to create a new row in the diffServSixTupleClfrTable 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 diffServSixTupleClfrNextFree?

Reading this object returns a currently-unused ID that a management station can use when creating a new row in the six-tuple classifier table, avoiding index collisions with existing filter entries.
