Chapter 9 Ethernet Operation
G1000-4 Performance and Maintenance Screens
Note The CTC automatically refreshes the counter values once right after a Baseline operation, so if traffic is
flowing during a baseline operation, some traffic counts may immediately be observed instead of zero
counts.
Note The Clear button will not cause the G1000-4 card to reset. Provisioning, enabling, or disabling a
G1000-4 port will not reset the statistics.
Note You can apply both the Baseline and the Clear functions to a single port or all ports on the card. To apply
Baseline or Clear to a single port, click the port column to highlight the port and click the Baseline or
Clear button.
Table 9-11 G1000-4 Statistics Values
Baseline Clicking Baseline resets the software counters (in that
particular CTC client only) temporarily to zero without
affecting the actual statistics on the card. From that point
on, only the delta in counters are displayed by this CTC.
These new base lined counters display only as long as the
user displays the Performance pane. If the user navigates to
another pane and comes back to the Performance pane, the
true actual statistics retained by the card display.
Refresh Manually refreshes the statistics
Auto-Refresh Sets a time interval for the automatic refresh of statistics
Clear Resets the actual counters on the card to zero; this change
is recognized by all management clients.
Table 9-12 Ethernet Parameters
Parameter Meaning
Link Status 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
Rx Packets Number of packets received since the last counter reset
Rx Bytes Number of bytes received since the last counter reset
Tx Packets Number of packets transmitted since the last counter reset
Tx Bytes Number of bytes transmitted since the last counter reset
Rx Total Errors Total number of receive errors
Rx FCS Number of packets with a Frame Check Sequence (FCS)
error. FCS errors indicate Frame corruption during
transmission
Rx Alignment Number of packets with alignment errors; alignment errors
are received incomplete frames
