Heading
Description
In Octets
Number of received octets over the interface
Out Octets
Number of transmitted octets over the interface
In Errors
Number of cells dropped due to uncorrectable HEC errors
In Unknown
Number of received cells discarded during cell header validation,
including cells with unrecognized VPI/VCI values, and cells with
invalid cell header patterns. If cells with undefined PTI values
are discarded, they are also counted here.
In Hec Errors

In Invalid Vpi
Vci Errors
Number of cells received with an unregistered VCC address.
In Port Not
Enable Errors

AAL5 Interface Statistics
Heading
Description
In Octets
Number of received AAL5/AAL0 CPCS PDU octets
Out Octets
Number of received AAL5/AAL0 CPCS PDU octets transmitted
In Ucast Pkts
Number of received AAL5/AAL0 CPCS PDUs passed to a
higher-layer for transmission
Out Ucast Pkts
Number of received AAL5/AAL0 CPCS PDUs received from a
higher layer for transmission
In Errors
