Port Configuration
This section describes how to configure port connections, mirror traffic from one
port to another, and run cable diagnostics.
Configuring by
Port List
Use the Interface > Port > General (Configure by Port List) page to enable/disable
an interface, set auto-negotiation and the interface capabilities to advertise, or
manually fix the speed, duplex mode, and flow control.
Command Usage
◆
Auto-negotiation must be disabled before you can configure or force a Gigabit
RJ-45 interface to use the Speed/Duplex mode or Flow Control options.
◆
When using auto-negotiation, the optimal settings will be negotiated between
the link partners based on their advertised capabilities. To set the speed, duplex
mode, or flow control under auto-negotiation, the required operation modes
must be specified in the capabilities list for an interface.
◆
The Speed/Duplex mode is fixed at 100full for 100BASE-FX transceivers and
1000full for Gigabit transceivers. When auto-negotiation is enabled, the only
attributes which can be advertised include flow control and symmetric pause
frames.
◆
The 1000BASE-T standard does not support forced mode. Auto-negotiation
should always be used to establish a connection over any 1000BASE-T port or
trunk. If not used, the success of the link process cannot be guaranteed when
connecting to other types of switches.
Note: Auto-negotiation is not supported for 1000BASE SFP transceivers.
Parameters
These parameters are displayed:
◆
Port – Port identifier. (Range: 1-52)
◆
Type – Indicates the port type. (1000BASE-T, 1000BASE SFP,)
◆
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 re-
enable it after the problem has been resolved. You may also disable an
interface for security reasons. (Default: Enabled)
◆
Autonegotiation (Port Capabilities) – Allows auto-negotiation to be enabled/
disabled. When auto-negotiation is enabled, you need to specify the
