cktATMAAL5CPIError
Module: CASCADE-MIB
OID (symbolic): CASCADE-MIB::cktATMAAL5CPIError
OID (numeric): 1.3.6.1.4.1.277.1.6.1.1.216
Node type: OBJECT-TYPE
Type: Counter
Access: read-only
Description: Number of received AAL5 packets with CPI errors The only valid value currently defined for the CPI field is all zeros
What is cktATMAAL5CPIError?
This read-only counter tracks received AAL5 packets with CPI (Common Part Indicator) errors, where the description notes the only currently valid value for the CPI field is all zeros, meaning any nonzero CPI value in the AAL5 trailer counts as an error. Since CPI is a largely vestigial/reserved field in AAL5, this counter mainly flags interoperability bugs or corruption in remote equipment that's populating that field incorrectly rather than a normal operational condition. An engineer seeing cktATMAAL5CPIError increment on a circuit connected to a particular vendor's equipment would suspect a firmware bug in that far-end device rather than a network transmission problem.
