Description: The VPI of the last cell with invalid cell header on the card
What is cardLastErrorVPI?
This reports the Virtual Path Identifier carried in the most recent cell that had an invalid header on this card. Paired with cardLastErrorVCI, this lets an admin identify the exact virtual circuit associated with the last header error, which is useful when trying to determine if errors are concentrated on one customer's PVC rather than spread randomly across the port. For example, seeing the same VPI value repeatedly in cardLastErrorVPI across multiple polls suggests one specific circuit is generating the header errors, not general line noise.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.277.1.7.2.1.94 snmpwalk -v2c -c public <target> CASCADE-MIB::cardLastErrorVPI
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.277.1.7.2.1.94.1 snmpget -v2c -c public <target> CASCADE-MIB::cardLastErrorVPI.1
