GBEI Statistics Summary
Message
Indicates the number of HDLC link errors that have occurred on
the Rx WAN interface. This error would most likely occur if there
are errors in the received signal from the satellite resulting in
corrupted frames.
Indicates the number of times that a GBEI buffer overrun has
occurred in the Rx direction (WAN to the LAN). This error would
most likely occur if there are errors in the received signal from the
satellite resulting in a corrupted framing structure.
Indicates the number of Ethernet packets received from the WAN
Indicates the number of times this error is likely to occur if the
LAN traffic to the modem exceeds that which can be HDLC
encapsulated per the configured modem data rate.
For debug only
Indicates the number of Ethernet frames transmitted to the WAN
The sum of lengths of all good Ethernet frames received from the
LAN
The sum of lengths of all bad Ethernet frames received from the LAN
The sum of good frames received from the LAN that have a unicast
destination MAC address
The sum of good frames received from the LAN that have a
broadcast destination MAC address
The sum of good frames received from the LAN that have a multicast
destination MAC address
The number of good flow control frames received from the LAN
The sum of collisions detected on the LAN
Removed, V1.3.1 and later
Total frames received from the LAN with a length of less than 64
octets and an invalid FCS
Total frames received form the LAN with a length greater than the
maximum size of octets but with a valid FCS
A count of the number of incoming packets from the LAN to GBEI
card that are overflowing the Tx Buffer and discarded
Removed, V1.3.1 and later
Total frames received from the LAN for which an error was detected
at the PHY
Total frames received from the LAN with a CRC error which was not
counted in the Fragments or Rx Err totals
The sum of the lengths of all Ethernet frames transmitted to the LAN
The sum of frames transmitted to the LAN that have a unicast
destination MAC address
The sum of frames transmitted to the LAN that have a broadcast
destination MAC address
The sum of frames transmitted to the LAN that have a multicast
destination MAC address
