15.5.2.1 G-Series Ethernet Statistics Window
The Ethernet statistics window lists Ethernet parameters at the line level. The Statistics window provides
buttons to change the statistical values shown. The Baseline button resets the displayed statistics values
to zero. The Refresh button manually refreshes statistics. Auto-Refresh sets a time interval at which
automatic refresh occurs. The G-Series Statistics window also has a Clear button. The Clear button sets
the values on the card to zero, but does not reset the G-Series card.

15.5.2 G-Series Ethernet Card Performance Monitoring Parameters
defines the G-Series Ethernet card Statistics parameters.
Meaning
A time stamp indicating the last time statistics were reset.
Indicates whether the Ethernet link is receiving a valid
Ethernet signal (carrier) from the attached Ethernet device;
up means present, and down means not present.
Number of packets received since the last counter reset.
Number of bytes received since the last counter reset.
Number of packets transmitted since the last counter reset.
Number of bytes transmitted since the last counter reset.
Total number of receive errors.
Number of packets with a Frame Check Sequence (FCS)
error. FCS errors indicate frame corruption during
transmission.
Number of packets with received incomplete frames.
Measures undersized packets with bad cyclic redundancy
check (CRC) errors.
Measures undersized packets with good cyclic redundancy
check (CRC) errors.
Total number of frames received that exceed the 1548-byte
maximum and contain CRC errors.
Number of packets received that are greater than 1530 bytes
in length.
Number of received Ethernet IEEE 802.3z pause frames.
Number of transmitted IEEE 802.3z pause frames.
Number of received packets dropped due to overflow in
G-Series frame buffer.
Number of transmit queue drops due to drops in the G-Series
frame buffer.
High-level data link control (HDLC) errors received from
SDH/SONET (see note).
Number of unicast packets received since the last counter
reset.
Number of unicast packets transmitted.
