Port Settings - Lane Control Tab - Viavi Xgig User Manual

Chapter 10, Xgig Performance Monitor Configuration
CDR (Clock Data Recovery)
This setting only applies to the 10GigE ports on the 40G Xgig1000 chassis. The CDR cleans the
signal output after passing through the analyzer. This is similar to a Digital Retime, but the signal
is not completely re-created. It is just cleaned and re-clocked. The default setting is off.
Note: If you are using copper cables, turning the CDR setting on prevents the training signals
from passing through the analyzer. If you want training signals to come through when using
copper cables, turn this setting off.
FEC (Forward Error Correction)
This setting only applies to 16G Fibre Channel ports with the
10GigE ports on the 2 port 10G Multi-function Xgig blade, and 10GigE ports at all speeds on
Xgig1000 systems. It allows you to specify whether FEC is enabled in the link or not. You can also
set this option to
link contains FEC traffic and will capture the traffic either way. This is the default setting.
Force Clock Re-lock to Incoming Data
This option only appears when an 8G blade FC port or 6G blade SAS/SATA port is being
monitored. When the Clock Detection Recovery (CDR) loses its lock on the incoming data signal,
the link speed cell will turn red and display the message
forces the re-locking of the clock to incoming data on the corresponding port. If the ports are not
locked or capturing, this menu will be grayed out.
For optical 8G blade FC ports, if this option fails to re-lock the signal, clean the fiber optic
connections and check the signal.
