cpIwfVpi
Module: CPIWF-MIB
OID (symbolic): CPIWF-MIB::cpIwfVpi
OID (numeric): 1.3.6.1.4.1.353.5.10.1.1.1.1
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: The VPI of the AAL2 VCC to which this CP-IWF is associated.
What is cpIwfVpi?
This read-only Integer32 reports the ATM VPI (Virtual Path Identifier) of the AAL2 VCC that this CP-IWF (customer-premises interworking function) uses to carry voice traffic. It lets an admin confirm which ATM virtual path the device's voice-over-AAL2 connection is riding on when tracing a call path through the ATM network. If calls are failing, the admin checks this value against the VPI configured on the upstream ATM switch to rule out a path mismatch.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.353.5.10.1.1.1.1 snmpwalk -v2c -c public <target> CPIWF-MIB::cpIwfVpi
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.353.5.10.1.1.1.1.1 snmpget -v2c -c public <target> CPIWF-MIB::cpIwfVpi.1
