dsx3LineIndex

Module: DS3-MIB

OID (symbolic): DS3-MIB::dsx3LineIndex

OID (numeric): 1.3.6.1.2.1.10.30.5.1.1

Node type: OBJECT-TYPE

Type: InterfaceIndex

Access: read-only

Description: This object should be made equal to ifIndex. The next paragraph describes its previous usage. Making the object equal to ifIndex allows proper use of ifStackTable.

Previously, this object was the identifier of a DS3/E3 Interface on a managed device. If there is an ifEntry that is directly associated with this and only this DS3/E3 interface, it should have the same value as ifIndex. Otherwise, number the dsx3LineIndices with an unique identifier following the rules of choosing a number that is greater than ifNumber and numbering the inside interfaces (e.g., equipment side) with even numbers and outside interfaces (e.g., network side) with odd numbers.

What is dsx3LineIndex?

This identifies the DS3/E3 interface this row's configuration applies to, and per the DESCRIPTION should be set equal to ifIndex so it lines up properly with ifStackTable. Admins use it to correlate DS3-specific config/stats rows back to the same interface shown in the standard IF-MIB interface table.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.2.1.10.30.5.1.1
snmpwalk -v2c -c public <target> DS3-MIB::dsx3LineIndex

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.2.1.10.30.5.1.1.1
snmpget -v2c -c public <target> DS3-MIB::dsx3LineIndex.1
