usdSmdsMajorNextIfIndex
Module: Unisphere-Data-SMDS-MIB
OID (symbolic): Unisphere-Data-SMDS-MIB::usdSmdsMajorNextIfIndex
OID (numeric): 1.3.6.1.4.1.4874.2.2.50.1.3
Node type: OBJECT-TYPE
Type: UsdNextIfIndex
Access: read-only
Description: Coordinate ifIndex value allocation for entries in usdSmdsMajorIfTable.
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 usdSmdsMajorNextIfIndex?
This read-only value returns the next available ifIndex for creating a new entry in usdSmdsMajorIfTable, or zero if none is free. It performs the same coordination role as usdSmdsNextIfIndex but specifically for SMDS major interfaces. An admin's provisioning tool would read this before creating a new usdSmdsMajorIfEntry to avoid index collisions.
