Chapter 9 Ethernet Operation
Green represents forwarding spans and purple represents blocked (protect) spans. If you have a packet

ring configuration, at least one span should be purple.

9.6.5 Ethernet Performance Screen

CTC provides Ethernet performance information that includes line-level parameters, the amount of port
bandwidth used, and historical Ethernet statistics.

9.6.5.1 Statistics Window

The Ethernet statistics screen lists Ethernet parameters at the line level.
Display the CTC card view for the Ethernet card and click the Performance > Statistics tabs to display
the screen.
The Baseline button resets the values on the Statistics tab to zero. The Refresh button manually refreshes
statistics. Auto-Refresh sets a time interval for automatic refresh of statistics to occur.

Ethernet Parameters
Meaning
Indicates whether or not link integrity is present; 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 alignment errors; alignment errors are
received incomplete frames.
Number of packets received that are less than 64 bytes in length.
Number of packets received that are greater than 1518 bytes in length
for untagged interfaces and 1522 bytes for tagged interfaces.
Number of transmit packets that are collisions; the port and the
attached device transmitting at the same time caused collisions.
Number of consecutive collisions.
Number of packets deferred.
