Configuring Auto-Negotiation
By default, the SCE 1000 line interface ports are configured with auto-negotiation enabled.
However, when using an external splitter, the auto-negotiation must be disabled.
Note
In order to prevent errors when in bypass mode, the system must be configured so that the speed and
duplex of both line interfaces is the same.
Note
If you change any parameters, you must save the new configuration settings.
Type copy running-config startup-config, and press Enter.
