Module: ACMIB

OID (symbolic): ACMIB::atmUniVpiSig

OID (numeric): 1.3.6.1.4.1.1751.2.18.5.1.1.23

Node type: OBJECT-TYPE

Type: INTEGER

Description: VPI value for the signalling channel for the UNI interface.

What is atmUniVpiSig?

This OID stores the Virtual Path Identifier (VPI) value used for ATM signaling traffic on this UNI interface, with a range from 0 to 255. Engineers must set this during initial ATM configuration to establish the correct VPI for signaling traffic, which must match the carrier's provisioning and the far-end equipment. A value of 0 typically indicates that the signaling channel uses VPI 0, the standard signaling path on most ATM interfaces.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.5.1.1.23
snmpwalk -v2c -c public <target> ACMIB::atmUniVpiSig

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.5.1.1.23.1
snmpget -v2c -c public <target> ACMIB::atmUniVpiSig.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.1751.2.18.5.1.1.23.1 i <value>
