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.
