16 Port Configuration

Configuring Interface Connections

You can use the Port Configuration or Trunk Configuration page to enable/disable an interface, set auto-negotiation and the interface capabilities to advertise, or manually fix the speed and duplex mode.

Command Attributes

•Name – Allows you to label an interface. (Range: 1-64 characters)

•Admin – Allows you to manually disable an interface. You can disable an interface due to abnormal behavior (e.g., excessive collisions), and then reenable it after the problem has been resolved. You may also disable an interface for security reasons.

•Speed/Duplex – Allows you to manually set the port speed and duplex mode (i.e., with auto-negotiation disabled).

•Autonegotiation (Port Capabilities) – Allows auto-negotiation to be enabled/ disabled. When auto-negotiation is enabled, you need to specify the capabilities to be advertised. When auto-negotiation is disabled, you can force the settings for speed, duplex mode, and flow control. The following capabilities are supported.

-10half - Supports 10 Mbps half-duplex operation

-10full - Supports 10 Mbps full-duplex operation

-100half - Supports 100 Mbps half-duplex operation

-100full - Supports 100 Mbps full-duplex operation

-1000full - Supports 1 Gbps full-duplex operation

(Default: Autonegotiation enabled; Advertised capabilities for

RJ-45: 1000BASE-T – 10half, 10full, 100half, 100full, 1000full;

SFP: 1000BASE-SX/LX/LH – 1000full)

•Media Type – Shows the forced/preferred port type to use for the combination ports. (ES4524D: Ports 21-24; ES4548D: Ports 45-48)

-Copper-Forced- Always uses the built-in RJ-45 port.

-SFP-Forced- Always uses the SFP port (even if module is not installed).

-SFP-Preferred-Auto- Uses SFP port if both combination types are functioning and the SFP port has a valid link.

•Trunk – Indicates if a port is a member of a trunk. To create trunks and select port members, see “Creating Trunk Groups” on page 17-1.

Note: Auto-negotiation must be disabled before you can configure or force the interface to use the Speed/Duplex Mode.
