Description
WAN Rx Overrun Count
Count of received frames that exceeded max frame length of 2K bytes in
length (Or) overflowed the HDLC buffer.
WAN Rx HDLC CRC Error Count
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.
WAN Rx HDLC Payload Bytes
The count of payload bytes that were received over satellite link
excluding any frame overhead.
WAN Rx HDLC Header Bytes
The count of HDLC header bytes received over satellite link including
control, HDLC address, Flow ID, and CRC.
WAN Rx HDLC Packet Count
Number of packets received over satellite link.
WAN Rx HDLC Address Match Packet
Count
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).
WAN Rx HDLC Address Filtered Packet
Count
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).
WAN Rx Err Invalid Flow ID
Number of packets which the flow identifier has been corrupted, does not
fall into the range of acceptable values.
WAN Rx Err SAR Reassemble
Number of packets unable to correctly reassemble a segmented packet.
WAN Rx Err Hdr Decomp
Number of packets unable to correctly decompress the header
information.
WAN Rx Err Mem Alignment
Number of packets discarded (caused by memory corruption).
WAN Rx Err Bad Crc
Number of corrupted packets indicated by CRC check.
WAN Rx Err DMA Reclaim
Number of times Receive DMA Reclaim Errors have occurred.
WAN Tx Err – No Route
Internal Traffic Statistics used for Factory Troubleshooting
WAN Tx Err – PktStart
WAN Tx Err – Pkt Front Length
WAN Tx Err – Pkt End Length
WAN Tx Err – Pkt Invalid Length
WAN Tx Err – PktDropped – Sat
overdriven
WAN Tx DMA Reclaim
Number of times Transmit DMA Reclaim Errors have occurred.
WAN Tx HDLC Header Bytes
This counter keeps track of number of HDLC header bytes transmitted
over satellite link.
WAN Tx HDLC Payload Bytes
Number of payload bytes transmitted over satellite link.
WAN Tx HDLC Packet Count
Count of packets transmitted over satellite link.
WAN Utilization
Percentage of current TX data rate being used for IP traffic (after
compression and framing)
Ethernet traffic destined to go over
WAN (kbps)
Bandwidth required to forward Ethernet traffic before compression.
Actual Satellite traffic (kbps)
Current satellite bandwidth being used.
Percentage of WAN Bandwidth saved
Displays percent of bandwidth being saved as a result of Header and/or
Payload Compression, and optimized satellite framing.
