EPP - Check the Current Link Quality
A Link-Quality parameter has been added to help support EPP functionality. If connectivity issues are
being observed check the current link quality using the

EPP - Diagnose
For ports diagnosed as Fair or Poor, simple steps can be performed to identify the faulty component.
Since the issue could be with the transceiver, cable, fiber, or the link partner, see the table below to help
determine if the issue is with the link partner and if enabling EPP may help.

If after diagnosing the problem it is determined that the issue is with the link partner and the Link-Quality
has been diagnosed to be Fair or Poor, EPP can be enabled allowing the system to operate with the defi-
cient receive channels. For example:

After enabling EPP continue to monitor the Link-Quality.

Configuring Energy Efficient Ethernet (802.3az)

Energy Efficient Ethernet (EEE) is a protocol to allow ports to operate in idle or low power mode when
there is no traffic to send. When EEE is enabled on a port it will advertise its EEE capability to its link
partner. If the partner supports EEE they will operate in EEE mode. If the partner does not support EEE

Diagnostic Action
•
Disconnect cable from link partner
•
Connect free cable end to unused port of OS6900
•
View the Link-Quality
Good - The link partner should be diagnosed and enabling EPP may help.
Fair or Poor - The direct-attached copper cable should be replaced.
•
Replace SFP+ transceiver on OS6900 port
•
View the Link-Quality
Good - The original SFP+ transceiver is faulty.
Fair or Poor - The fiber cable or link partner should be diagnosed and
enabling EPP may help.
