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, and flow control.
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).
Note:
The 1000BASE-T standard does not support forced mode. Always use
auto-negotiation to establish a connection over any 1000BASE-T port or trunk.
• Flow Control – Allows automatic or manual selection of flow control.
• 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
