Description
Max. PDU size limitation for this AAL connection.
No. of frames received.
No. of AAL cells received.
Total data in bytes received.
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.
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.
Total frames transmitted.
Total cells transmitted.
Total data transmitted in bytes.
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.
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).
Out of cells for transmit. Internal cell buffer could
not be allocated for transmitting cells.
Discarded Transmitted Cells because the
connection is not established | disconnected |
closed.
Discarded Received Cells because connection not
established | disconnected | closed.
AAL5 only. CRC-32 header checksum in is wrong.
No. of SAR reassembly timeouts. Frames could not
be reassembling and discarded.
Frame size is larger than the max. size of PDU.
