Module: ADN-MIB
OID (symbolic): ADN-MIB::adnAtmAal5PerfCpiErrors
OID (numeric): 1.3.6.1.4.1.637.3.1.4.37.1.20.1.2
Node type: OBJECT-TYPE
Type: Counter
Access: read-only
Description: The number of ATM Adaptation Layer 5 (AAL5) Common Part Convergence Sublayer (CPCS) PDUs discarded on this Virtual Channel Link (VCL) because the value of the Common Part Interface (CPI) field in the PDU trailer is not 0.
What is adnAtmAal5PerfCpiErrors?
This counter tracks AAL5 protocol data units dropped on a Virtual Channel Link because the Common Part Interface field in the PDU trailer contained an invalid value (should always be 0). Engineers monitor this to detect protocol stack failures or interoperability issues with remote endpoints. A count of 18 means 18 PDUs with invalid CPI values were detected and discarded.
