Max PDU Max. PDU size limitation for this AAL connection.
Rx Frames No. of frames received.
Rx Cells No. of AAL cells received.
Rx Bytes Total data in bytes received.
Rx Error Cells No. of received cells are dropped due to:
-Connection is not established/closed.
-Could not allocation internal cell buffer
-Value of STF (Start Field) in header is incorrect.
-Cells Overflow (the internal queue for storing the
cell reaches it maximum size).
-Cells Re-Assembly Errors
-CRC checksum errors.
Rx Error Frames No. of received frames are dropped due:
-Could not allocation internal cell buffer
-Cells Overflow (the internal queue for storing the
cell reaches it maximum size)
-Frames re-assembly errors
-Re-assembly timeout
-CRC checksum errors.
Tx Frames Total frames transmitted.
Tx Cells Total cells transmitted.
Tx Bytes Total data transmitted in bytes.
Tx Discarded No. of discarded transmitting cells due to:
-Could not allocation internal cell buffer
-Cells Overflow (the internal queue for storing the
cell reaches it maximum size)
-Connection is not established/closed
-Transmitting frame is empty
-size of frame is larger than the PDU size.
Tx OverFlow Transmitted Cells Overflow. The internal SAR
transmitting queue for storing the cell reached its
maximum size (64), so it can not hold more
outgoing cell).
Tx UnderFlow Out of cells for transmit. Internal cell buffer could
not be allocated for transmitting cells.
Tx Inactive Discarded Transmitted Cells because the
connection is not established | disconnected |
closed.
Rx Inactive Discarded Received Cells because connection not
established | disconnected | closed.
CRC 32 Errors The size AAL5 only. CRC-32 header checksum in is wrong.
Reassembly Timeouts No. of SAR reassembly timeouts. Frames could not
be reassembling and discarded.
Frames too Long Frame size is larger than the max. size of PDU.
