Use the Interface > Port > General (Show Information) page to display the current connection status, including link state, speed/duplex mode, flow control, and auto-negotiation.
Port identifier.
Indicates the port type. (1000BASE-T, 1000BASE SFP, 10GBASE SFP+).
Interface label.
Shows if the port is enabled or disabled.
Indicates if the link is Up or Down.
Shows the reason this interface has been shut down if applicable. Some of the reasons for shutting down an interface include being administratively disabled, or exceeding traffic boundary limits set by auto traffic control.
Shows if auto-negotiation is enabled or disabled.
Shows the current speed and duplex mode.
Shows the flow control type used.
Shows if a notification message will be sent whenever a port link is established or broken. (Default: Enabled)
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.
Port identifier.
Indicates the port type. (1000BASE-T, 1000BASE SFP, 10GBASE SFP+).
Allows you to label an interface. (Range: 1-64 characters)
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)
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, mode, and flow control.The following capabilities are supported.
Supports 10 Mbps half-duplex operation.
Supports 10 Mbps full-duplex operation.
Supports 100 Mbps half-duplex operation.
Supports 100 Mbps full-duplex operation.
Not supported.
Supports 1000 Mbps full-duplex operation.
Symmetric exchange of transmit and receive pause frames.
Flow control can eliminate frame loss by "blocking" traffic from end stations or segments connected directly to the switch when its buffers fill. When enabled, back pressure is used for half-duplex operation and IEEE 802.3-2005 (formally IEEE 802.3x) for full-duplex operation.
Default: Autonegotiation enabled; Advertised capabilities for
100BASE-FX (SFP) - 100full
1000BASE-T - 10half, 10full, 100half, 100full, 1000full;
1000BASE-SX/LX/ZX (SFP/SFP+) - 1000full
10GBASE- CR/SR/LR/LRM (SFP+) ?10Gfull
Issues a notification message whenever a port link is established or broken. (Default: Disabled)
Allows you to manually set the port speed and duplex mode. (i.e., with auto-negotiation disabled)
Allows automatic or manual selection of flow control. (Deault: Enabled)
Use the Interface > Port > General (Configure by Port Range) 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. For more information on command usage and a description of the parameters (except for the trap command), refer to the preceding section on "Configuring by Port List."
