cpIwfVci
Module: CPIWF-MIB
OID (symbolic): CPIWF-MIB::cpIwfVci
OID (numeric): 1.3.6.1.4.1.353.5.10.1.1.1.2
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: The VCI of the AAL2 VCC to which this CP-IWF is associated.
What is cpIwfVci?
This read-only Integer32 reports the ATM VCI (Virtual Channel Identifier) of the AAL2 VCC that this CP-IWF uses to carry voice traffic, paired with the VPI to fully identify the ATM connection. It lets an admin verify the exact virtual channel in use when correlating this device's configuration with the ATM switch side. Together with cpIwfVpi, a mismatch here versus the CO-IWF's expected VCI would explain why voice calls are not connecting.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.353.5.10.1.1.1.2 snmpwalk -v2c -c public <target> CPIWF-MIB::cpIwfVci
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.353.5.10.1.1.1.2.1 snmpget -v2c -c public <target> CPIWF-MIB::cpIwfVci.1
