Page 45: Introduction To The Ml3000
Overview 2.1.1 Introduction to the ML3000 The Multilink ML3000 Ethernet Switch provides rack-mount space efficiency and advanced port configurability for heavy duty industrial applications where maximum fiber port count and diversity are required. New advanced thermal design techniques (patent pending) enable the ML3000 to deliver high reliability and configurability even at extended operating temperatures.
Page 46: Design Aspects
2.1.2 Design Aspects Designed for use in network traffic centers, the MultiLink ML3000 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.

Page 69: Functionality
4.1.1 Switching Functionality The MultiLink ML3000 provides switched connectivity at Ethernet wire-speed. The ML3000 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 ML3000, but local traffic on a port will not consume any of the bandwidth on any other port.

MNS software port settings and can check the port status of each port after the change. When Multilink ML3000 RJ-45 copper ports are set for auto-negotiation and are connected to another auto-negotiating device, there are 4 different speed and F/H modes possible depending on what the other device supports.
Page 71: Flow Control
When operating in 100Mb half-duplex mode, cable distances and hop-counts may be limited within that collision domain. The Path Delay Value (PDV) bit-times must account for all devices and cable lengths within that domain. For Multilink ML3000 Fast Ethernet switched ports operating at 100Mb half-duplex, the bit time delay is 50BT.

Page 189: Overview
The Generic Attribute Registration Protocol (GARP) and VLAN registration over GARP is called GVRP. GVRP is defined in the IEEE 802.1q and GARP in the IEEE 802.1p standards. To utilize the capabilities of GVRP, GE Multilin recommends that the user become familiar with the concepts and capabilities of IEEE 802.1q.
Page 190: Gvrp Operations
There must be one common VLAN (that is, one common VID) connecting all of the GVRP- Note aware devices in the network to carry GVRP packets. GE Multilin recommends the default VLAN (DEFAULT_VLAN; VID = 1), which is automatically enabled and configured as NOTE untagged on every port of the MultiLink family of switches.

Page 193 Auto, and Forbid options are configured in the VLAN context. Since dynamic VLANs operate as tagged VLANs, and it is possible that a tagged port on one device may not communicate with an untagged port on another device, GE Multilin recommends that you use tagged VLANs for the static VLANs.
Page 194: Configuring Gvrp Through The Command Line Interface
Similarly, the switch advertises its static VLANs to other GVRP-aware devices. A GVRP-enabled switch does not advertise any GVRP-learned VLANs out of the port(s) on which it originally learned of those VLANs. 11–6 MULTILINK ML3000 ETHERNET COMMUNICATIONS SWITCH – INSTRUCTION MANUAL...
