Overview of Basic Port Settings
You can perform the following basic settings on a port:
-
Entering interface configuration mode: Interface configuration mode is supported only on Ethernet ports.
-
Enabling a port: By default, all device ports are enabled or in link-up state when a device is online. However, for security reasons, certain ports are disabled or in link-down state even when a device is online.
-
Configuring port description: You can configure a port's description to identify the port.
-
Configuring port speed: You can configure a port's speed to configure the rate of data flow.
-
Configuring speed control: For every 2-Gigabits ports that are connected, and speeds configured in force mode, you need to configure one port in primary mode and the other in secondary mode to enable them to dock successfully.
