15.6 15.6.2 G-Series Ethernet Card Performance Monitoring Parameters

15.6.2 G-Series Ethernet Card Performance Monitoring Parameters
CTC provides Ethernet performance information, including line-level parameters, port bandwidth
consumption, and historical Ethernet statistics. The G-Series Ethernet performance information is
divided into the Statistics, Utilization, and History tabbed windows within the card view Performance
tab window.
15.6.2.1 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.

defines the G-Series Ethernet card statistics parameters.
G-Series Ethernet Statistics Parameters
Definition
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 FCS error. FCS errors indicate frame corruption
during transmission.
Number of packets with received incomplete frames.
Measures undersized packets with bad CRC errors.
Measures undersized packets with good CRC errors.
The 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 SONET/SDH
(see Note).
