Entry Description
[RO] Count of received frames that failed packet processor CRC check.
Indicates that a Payload Compressed Packet was received that could not
be decompressed.
Count of aborted frames and octet error frames.
Count of received frames that exceeded max frame length of 2K bytes in
length (Or) overflowed the HDLC buffer.
Number of received frames that failed HDLC CRC check. Indicates that a
corrupted packet was received and is usually due to a marginal satellite
link.
The count of payload bytes that were received over satellite link excluding
any frame overhead.
The count of HDLC header bytes received over satellite link including
control, HDLC address, Flow ID, and CRC.
Number of packets received over satellite link.
Number of packets received that matched any of the 4 RX HDLC
Addresses defined in the Satellite interface (not used with version 1.7.# and
later).
Number of packets received that did not match any of the 4 RX HDLC
Addresses defined in the Satellite interface (not used with version 1.7.# and
later).
Number of packets which the flow identifier has been corrupted, does not
fall into the range of acceptable values.
Number of packets unable to correctly reassemble a segmented packet.
Number of packets unable to correctly decompress the header information.
Number of packets discarded (caused by memory corruption).
Number of corrupted packets indicated by CRC check.
Internal Traffic Statistics used for Factory Troubleshooting
This counter keeps track of number of HDLC header bytes transmitted over
satellite link.
Number of payload bytes transmitted over satellite link.
Count of packets transmitted over satellite link.
Percentage of current TX data rate being used for IP traffic (after
compression and framing)
Bandwidth required to forward Ethernet traffic before compression.
Current satellite bandwidth being used.
Displays percent of bandwidth being saved as a result of Header and/or
Payload Compression, and optimized satellite framing.
C Resets all WAN statistics.
