  • Page 16: Firmware Overview

    The documentation reflects features of MultiLink Switch Software version 1.7.x or later. If your switch is not at the current version, GE Multilin recommends upgrade to version 1.7.x or later. Please refer to the GE Multilin website for information on upgrading the MultiLink Switch Software.
  • Page 17: Before Starting

    1.4.3 Before Starting This section explains how to setup the GE MultiLink family of switches using the console port on the switch. Some of the functionality includes setting up the IP address of the switch, securing the switch with a user name and password, setting up VLANs and more.
  • Page 18: Command Line Interface Firmware

    Once the switch is configured with an IP address, the command line interface (or CLI) is also accessible using telnet as well as the serial port. Access to the switch can be either through the console interface or remotely over the network. Simultaneous access (that is, through the console port as well as through the network) to the MultiLink switch is not permitted.
  • Page 19: Console Screen

    Management on page 1–14. 1.5.4 Logging In for the First Time For the first time, use the default user name and passwords assigned by GE. They are: • Username: manager • Username: operator We recommend you login as manager for the first time to set up the IP address as well as change user passwords or create new users.
  • Page 20: Setting The Ip Parameters

    Step 3: If there is no response from either a DCHP or BOOTP server, or if the switch is not connected to a network, the switch will assign itself an IP address. The ML2400 will check to see if IP address 192.168.1.2, with a network mask of 255.255.255.0, is free. If so, it will assume these values.

  • Page 32: Ml2400 Firmware Updates

    1.7.1 Updating MultiLink Firmware This section describes how to upgrade the firmware on a Multilink switch, either locally at the console port or remotely over the network using FTP or TFTP. Depending on the update process (serial/console port or network), ensure the necessary tools listed below are available, tested and working before you begin.
  • Page 33: Updating Through The Enervista Software

    Login to the switch and use the and upload the configuration file (if necessary). Download the latest MultiLink firmware from the GE Multilin web site. Save this file on FTP or TFTP. Ensure the FTP or TFTP path is configured.
  • Page 34 INTRODUCTION If using FTP, save the configuration before proceeding. GE Multilin recommends a two-step update: first save the configuration to the ftp server, then load the new image and restart the switch (refer to Saving Configuration on page 5–19 for details on saving the configuration).

    2.1.2 Design Aspects Designed for use in network traffic centers, the MultiLink ML2400 Ethernet Switch is easy to install and use. Addresses of attached nodes are automatically learned, maintained, and aged out, adapting the switching services to network changes. LEDs provide status information on each port.

    The fiber ports support fiber cabling distances according to the 10Base-FL and 100Base- FX standards, i.e., 2 km distance for multi-mode fiber. A single-mode option for greater distance may be available as a special order, contact GE Multilin. The combo four-port modules are combinations of copper and fiber media, available as two 10/100 switched RJ45 copper ports and two 100 Mb switched multi-mode fiber ST or SC ports as shown below.

    4.1.1 Switching Functionality The MultiLink ML2400 provides switched connectivity at Ethernet wire-speed. The ML2400 supports10/100 Mbps for copper media and 10 or 100 Mb separate traffic domains for fiber ports to maximize bandwidth utilization and network performance. All ports can communicate to other ports in a ML2400, but local traffic on a port will not consume any of the bandwidth on any other port.
  • Page 62: Address Learning

    Up-link Manual Switches (for RJ45 port only) The module has a manual up-link switch, located on the inside of the board next to the 10/ 100Mb (RJ45) port # 1 which it controls. It enables the port's cable to be cascaded (X) to a 10/100Mb repeater or switching hub in the network.
  • Page 63: Flow Control

    The ML2400 incorporates a flow-control mechanism for full-duplex mode. Flow-control reduces the risk of data loss if a long burst of activity causes the switch to save frames until its buffer memory is full. This is most likely to occur when data is moving from a 100 Mb port to a 10 Mb port and the 10 Mb port is unable to keep up.
  • Page 64 In half-duplex mode, the ML2400 implements a back-pressure algorithm on 10/100 Mb Note ports for flow control. That is, the switch prevents frames from entering the device by forcing a collision indication on the half-duplex ports that are receiving. This temporary “collision”...

    The telnet client is enabled on the ML2400. The ML2400 supports five simultaneous sessions on a switch: four telnet sessions and one console session. This allows many users to view, discuss, or edit changes to the ML2400. This is also useful when two remote users want to view the switch settings.
  • Page 74 The ML2400 will time out an idle telnet session. It may be useful to see who is currently connected to the switch. It may also be useful for a person to remotely terminate a telnet session. To facilitate this, the ML2400 supports the following two commands: show session kill session id=<session>...
  • Page 75: E Xample

    This is shown using the operator session is then terminated using the A maximum of four simultaneous telnet sessions are allowed at any time on the switch. Note The commands in these telnet windows are executed in a round robin fashion; that is, if one window takes a long time to finish a command, the other windows may encounter a delay before the command is completed.
  • Page 76: Setting Parameters

    To be compliant with IT or other policies the console parameters can be changed from the CLI interface. This is best done by setting the IP address and then telnet over to the switch. Once connected using telnet, the serial parameters can be changed. If you are using the serial port, remember to set the VT-100 emulation software properties to match the new settings.
