usdSmdsSubNextIfIndex
Module: Unisphere-Data-SMDS-MIB
OID (symbolic): Unisphere-Data-SMDS-MIB::usdSmdsSubNextIfIndex
OID (numeric): 1.3.6.1.4.1.4874.2.2.50.1.5
Node type: OBJECT-TYPE
Type: UsdNextIfIndex
Access: read-only
Description: Coordinate ifIndex value allocation for entries in usdSmdsSubIfTable.
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 usdSmdsSubNextIfIndex?
This read-only value returns the next available ifIndex for a new entry in usdSmdsSubIfTable, or zero if none remain. It's the same index-coordination mechanism as the other usdSmds*NextIfIndex objects, but scoped to SMDS subinterfaces. An admin's automation would query this immediately before creating a new usdSmdsSubIfEntry.
