    The documentation reflects features of MultiLink Switch Software version 1.6.1 or later. If your switch is not at the current version, GE Multilin recommends upgrade to version 1.6.1 or later. Please refer to the GE Multilin website for information on upgrading the MultiLink Switch Software.

  • Page 15: 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 16: Command Line Interface Software

    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 17: Console Screen

    Ensure both software components are installed before proceeding. The ML1600 can search the network for commonly used services that can issue an IP address. If the switch is connected to a network, the ML1600 uses the following process to find an IP address.

  • Page 18: Setting The Ip Parameters

    Step 2: If there is no response from a DCHP server, the ML1600 will query for a BOOTP server. If the server responds, the ML1600 will acquire and set the assigned IP address. To manage the switch, determine the assigned IP address and enter as follows in Internet Explorer: https://<assigned_IP_address>...

The 1000 Mb Gigabit fiber-port modules on the ML1600 are normally set (factory default) to operate in AUTO mode for best fiber distance and performance. The 1000 Mbps SC fiber-optic module on the Gigabit-SX and Gigabit-LX transceivers are compatible with the IEEE 802.3z Gigabit standards.

    3.2.1 Description The ML1600 switches are specifically designed to support standard Ethernet media types within a single unit. This is accomplished by using a family of modules that are individually selected and configured. Refer to Communications Modules on page 2–3 for details on these modules.

    3.2.5 Connecting RJ45 Twisted Pair The RJ45 ports of the ML1600 can be connected to the following two media types: 100Base-TX and 10Base-T. CAT Five cables should be used when making 100Base-TX connections. When the ports are used as 10Base-T ports, CAT.3 may be used. In either case, the maximum distance for unshielded twisted pair cabling is 100 m (328 ft.).

    4.1.6 Auto-negotiation (for fast Ethernet copper ports) The managed ML1600 Fast Ethernet copper ports can be set for either fixed 100 Mb speed or for 10/100 full/half-duplex n-way auto-negotiation per the IEEE802.3u standard. The selection is made via the ML1600 software. The factory default setting is for auto- negotiation.

  • Page 59: Flow Control

    If the device at the other end is not an auto-negotiating device, the ML1600 RJ45 ports will try to detect its idle signal to determine 10 or 100 speed, and will default to half-duplex at that speed per the IEEE standard.

    FUNCTIONALITY In half-duplex mode, the ML1600 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”...

    IGMP. 15.1.2 IGMP Concepts The ML1600 supports IGMP L2 standards as defined by RFC 1112. IGMP is disabled by default and needs to be enabled on the MultiLink family of switches. IP multicasting is defined as the transmission of an IP datagram to a “host group”, a set of zero or more hosts identified by a single IP destination address.
  • Page 236 IGMP (in the MultiLink implementation of IGMP, a multicast router is not necessary as long as a switch is configured to support IGMP with the querier feature enabled). A set of hosts, routers, and/or switches that send or receive multicast data streams to or from the same source(s) is termed a multicast group, and all devices in the group use the same multicast group address.
