usdHdlcNextIfIndex
Module: Unisphere-Data-HDLC-MIB
OID (symbolic): Unisphere-Data-HDLC-MIB::usdHdlcNextIfIndex
OID (numeric): 1.3.6.1.4.1.4874.2.2.9.1.1
Node type: OBJECT-TYPE
Type: UsdNextIfIndex
Access: read-only
Description: Coordinate ifIndex value allocation for entries in usdHdlcIfTable.
A GET of this object returns the next available ifIndex value to be used to create an entry in the associated interface table; or zero, if no valid ifIndex value is available. This object also returns a value of zero when it is the lexicographic successor of a varbind presented in an SNMP GETNEXT or GETBULK request, for which circumstance it is assumed that ifIndex allocation is unintended.
Successive GETs will typically return different values, thus avoiding collisions among cooperating management clients seeking to create table entries simultaneously.
What is usdHdlcNextIfIndex?
This value returns the next available ifIndex value that a manager should use when creating a new entry in the HDLC interface table, or zero if none is available or if it was reached as the lexicographic successor of an unrelated GETNEXT/GETBULK walk. Admins or provisioning scripts read this immediately before creating a new HDLC interface, since successive reads return different values to avoid collisions between multiple management clients creating interfaces simultaneously. For example, reading a value of 45 tells the provisioning system to use ifIndex 45 when creating the next HDLC interface row.
