atmVnnVpiSig

Module: ACMIB

OID (symbolic): ACMIB::atmVnnVpiSig

OID (numeric): 1.3.6.1.4.1.1751.2.18.5.17.1.23

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

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

What is atmVnnVpiSig?

This OID stores the Virtual Path Identifier (VPI) value used for the ATM signaling channel on the UNI interface, ranging from 0 to 255. Network engineers configure this to ensure that the control plane signaling uses a different path than data traffic, isolating management from user traffic. Setting VPI to 0 reserves path 0 for signaling, which by convention carries the UNI management and connection control messages separate from data paths 1 and above.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.5.17.1.23
snmpwalk -v2c -c public <target> ACMIB::atmVnnVpiSig

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.5.17.1.23.1
snmpget -v2c -c public <target> ACMIB::atmVnnVpiSig.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.1751.2.18.5.17.1.23.1 i <value>

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> atmVnnVpiSig.1
