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 61: Switching Functionality
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.

The MultiLink switches can compensate for situations where only the switch receiver fiber cable is broken.
Page 147 It is recommended to enable the Link Loss Alert (LLA) feature on ports that are connected to end devices. LLA should be disabled for switch ports connected in a ring. The Link Loss Alert feature is enabled by default on 10 MB Fiber Optic ports, and disabled by default on 100 MB Fiber Optic ports.

Page 153: Vlan Description
MultiLink switches. A VLAN is a group of ports designated by the switch as belonging to the same broadcast domain. The IEEE 802.1Q specification establishes a standard method for inserting VLAN membership information into Ethernet frames.
Page 154 L3-switch). The routing function can be done internally to a L3-switch. One advantage of an L3 switch is that the switch can also support multiple VLANs. The L3 switch can thus route traffic across multiple VLANs easily and provides a cost effective solution if there are may VLANs defined.
Page 155: Tag Vlan Vs. Port Vlan
802.1Q VLANs. 802.1Q VLANs aren't limited to one switch. VLANs can span many switches. Sharing VLANs between switches is achieved by inserting a tag with a VLAN identifier (VID) into each frame.

Page 199: Rstp Concepts
RSTP converges in less than one second. RSTP also offers a number of other significant innovations. These include MULTILINK ML2400 ETHERNET COMMUNICATIONS SWITCH – INSTRUCTION MANUAL Protocol • Topology changes in STP must be passed to the root bridge before they can be propagated to the network.
Page 200: Transition From Stp To Rstp
Even though RSTP inter-operates with STP, RSTP is more efficient at establishing the network path and network convergence in case of a very fast failure. As such, GE recommends that all network devices be updated to support RSTP. RSTP offers convergence times typically less than one second.
Page 201 CHAPTER 13: RAPID SPANNING TREE PROTOCOL MULTILINK ML2400 ETHERNET COMMUNICATIONS SWITCH – INSTRUCTION MANUAL Under some circumstances, it is possible for the rapid state transitions employed by RSTP to result in an increase in the rates of frame duplication and the order in which the frames are sent and received.

Page 224: Diffserv And Qos
The MultiLink family of switches has two priority queues, 1 (low) and 0 (high).When tagged packets enter a switch port, the switch responds by placing the packet into one of the two queues, and depending on the precedence levels the queue could be rearranged to meet the QoS requirements.
Page 225 • TAG QoS: if a packet contains a tag, the port on which the packet was received • ToS QoS: (Layer 3) when a port is set to ToS QoS, the most significant 6-bits of the MULTILINK ML2400 ETHERNET COMMUNICATIONS SWITCH – INSTRUCTION MANUAL FIGURE 14–2: IP Precedence ToS Field in an IP Packet Header type of packet.

Page 227 [type=<port|tag|tos>] [port=<port|list|range>] Sometimes it is necessary to change the priority of the packets going out of a switch. For example, when a packet is received untagged and has to be transmitted with an addition of the 802.1p priority tag, the tag can be assigned depending on the example if the received on that port will be tagged with a priority low upon transmit.
