IP Header Compression Statistics Report
This report is available when ATM PVC Encapsulation Type RFC 1483 is
selected, an IP address is assigned and IP Header Compression is enabled on
the ATM Interface.
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 cannot hold more outgoing
cells)
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 AAL5 only. CRC-32 header checksum is wrong
Reassembly Timeouts No. of SAR reassembly timeouts. Frames could not be
reassembled and discarded
Frames too Long Frame size is larger than the max. size of PDU
