Interface Configuration
Overview
This chapter describes the following topics:
Port Configuration
- Configures connection settings, including auto- negotiation, or manual setting of speed, duplex
mode, and flow control.
Displaying Statistics
- Shows Interface, Etherlike, and RMON port statistics in table or chart form.
Displaying Statistical History
- Displays statistical history for the specified interfaces.
Displaying Transceiver Data
- Displays identifying information, and operational parameters for optical transceivers which
support DDM.
Configuring Transceiver Thresholds
- Configures thresholds for alarm and warning messages for optical transceivers
which support DDM.
Trunk Configuration
- Configures static or dynamic trunks.
Saving Power
- Adjusts the power provided to ports based on the length of the cable used to connect to other devices.
Local Port Mirroring
- Sets the source and target ports for mirroring on the local switch.
Remote Port Mirroring
- Configures mirroring of traffic from remote switches for analysis at a destination port on the local
switch.
Traffic Segmentation
- Configures the uplinks and down links to a segmented group of ports.
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 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.
The following table lists the options on this page:
Interface - Port (General) Options
Port
Port identifier. (Range: 1-10/26/28/52)
Type
Indicates the port type. (1000BASE-T or 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 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.
• 10h - Supports 10 Mbps half-duplex operation.
• 10f - Supports 10 Mbps full-duplex operation.
• 100h - Supports 100 Mbps half-duplex operation.
• 100f - Supports 100 Mbps full-duplex operation.
• 1000f - Supports 1000 Mbps full-duplex operation.
• Sym - Symmetric exchange of transmit and receive pause frames.
• FC - 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: Auto-negotiation enabled; Advertised capabilities for 100BASE-FX (SFP) - 100full
1000BASE-T - 10half, 10full, 100half, 100full, 1000full 1000BASE-SX/LX/ZX (SFP) - 1000full
Speed/Duplex
Allows you to manually set the port speed and duplex mode. (i.e., with auto-negotiation disabled)
