Product Overview This chapter provides the following information: • Product Description • Features • Front and Rear Panel Component Descriptions • Feature Summaries • Application Example Description This section describes Layer 3 functionality and Layer 2 and Layer 3 features of the VH-8G-L3. Some background information about Ethernet/Fast Ethernet, Gigabit Ethernet, and switching technology is presented.
The VH-8G-L3 can be thought of as eight Gigabit Ethernet Layer 2 switching domains with a wire-speed router between each domain. It can be deployed in a network between a traditional router and the intranetwork. The traditional router and its associated WAN interface would then handle routing between the intranetwork and the WAN (the Internet, for example) while the Layer 3 switch would handle routing within the LAN (between the Fast Ethernet Layer 2 domains).
traditional collapsed backbone router. The VH-8G-L3 Layer 3 switch communicates with a WAN router using a standard Gigabit Ethernet port. Multiple VH-8G-L3 switches can also be linked. Features The VH-8G-L3 was designed for easy installation and high performance in an environment where traffic on the network and the number of users increase continuously. Switch features include: Ports • Six 1000BASE-SX (SC-type fiber transceiver). • Two GBIC-based Gigabit Ethernet ports.
• 8K active MAC address entry table per device with automatic learning and aging (10 to 9999 seconds). • 512 KB packet buffer per device. • Broadcast and Multicast storm filtering. • Supports Port Mirroring. • Supports Port Trunking – up to four trunk groups may be set up. One trunk group can have from two to eight ports. • 802.1D Spanning Tree support. • 802.1Q Tagged VLAN support – up to 63 User-defined VLANs per device (one VLAN is reserved for internal use).
• Supports PIM Dense Mode (draft-ietf-pim-v2-dm-03.txt). • Supports DVMRP (draft-ietf-idmr-dvmrp-v3-09.txt). • Supports Username to IP address mapping. • Supports IP multi-netting. • Supports IP packet de-fragmentation. • Supports Path MTU discovery. • Supports 802.1D frame support. Traffic Classification and Prioritization • Based on 802.1p priority bits. • Based on IP source and destination addresses. • 4 priority queues. • Supports Port and MAC based priorities.
• Built-in SNMP management: Bridge MIB (RFC 1493) RMON MIB (RFC 1757) – 4 groups MIB-II (RFC 1213) Interface MIB ext. (RFC 2233) CIDR MIB (RFC 2096) – excluding the IP Forwarding Table. 802.1p MIB (RFC 2674). • Supports Web-based management. • TFTP support. • BOOTP support. • IP filtering on the management interface. • DHCP Client support. • DHCP Relay Agent. • Password enabled.
theoretical throughput over 100Mbps Fast Ethernet and a one hundred-fold increase over 10Mbps Ethernet. Since it is compatible with all 10Mbps and 100Mbps Ethernet environments, Gigabit Ethernet provides a straightforward upgrade without wasting a company’s existing investment in hardware, software, and trained personnel. Front Panel The front panel of the Switch consists of LED indicators, an RS-232 communication port, two GBIC-based Gigabit Ethernet ports, and six 1000BASE-SX ports. Figure 1-1.
• The AC power connector is a standard three-pronged connector that supports the power cord. Plug-in the female connector of the provided power cord into this socket, and the male side of the cord into a power outlet. Supported input voltages range from 100 ~ 240 VAC at 50 ~ 60 Hz. Side Panels The right side panel of the Switch contains two system fans (see the top part of the diagram below). The left side panel contains heat vents. Figure 1-3.
Figure 1-4. The LED indicators • Power This indicator on the front panel will light green approximately 2 seconds after the Switch is powered on to indicate the ready state of the device. The LED will blink green while downloading new software for the Switch, or if the system’s configuration has changed and will light yellow when an error occurs. • Link/Act These indicators are located to the left of each port. They are lit when there is a secure connection (or link) to a device at any of the ports.
network administrator can manage, control and monitor the switch from the console program. The VH-8G-L3 contains a CPU, memory for data storage, flash memory for configuration data, operational programs, and SNMP agent firmware. These components allow the switch to be actively managed and monitored from either the console port or the network itself (out-of-band, or in-band).
primary link. Once the Spanning Tree Protocol is configured and enabled, primary links are established and duplicated links are blocked automatically. The reactivation of the blocked links (at the time of a primary link failure) is also accomplished automatically – without operator intervention. Port Trunking Port trunking is used to combine a number of ports together to make a single high-bandwidth data pipeline.
Broadcast storms consist of broadcast packets that flood and/or are looped on a network causing noticeable performance degradation and in extreme cases, network failure. Broadcast storms can be caused by malfunctioning NICs, bad cable connections and applications or protocols that generate broadcast traffic, among others. Broadcast storms have long been a concern for network administrators with routers traditionally being used to prevent their occurrence, and if that failed, limit their scope.

2. Installation Inspecting Your Shipment Open the shipping carton of the Switch and carefully unpack its contents. The carton should contain the following items: • One VH-8G-L3 8-port Gigabit Ethernet Layer 3 Switch. • Mounting kit: 2 mounting brackets and screws. • Four rubber feet with adhesive backing. • One AC power cord. • One ESD wrist strap. • Product Documentation. If any item is found missing or damaged, please contact your local Enterasys sales agent for replacement.
Desktop or Shelf Installation When installing the Switch on a desktop or shelf, the rubber feet included with the device should first be attached. Attach these cushioning feet on the bottom at each corner of the device. Allow adequate space for ventilation between the device and the objects around it. Figure 2-1. Installing rubber feet for desktop installation Rack Installation The VH-8G-L3 can be mounted in an EIA standard-sized, 19-inch rack, which can be placed in a wiring closet with other equipment.
Figure 2-2B. Installing the Switch on an equipment rack Power on The VH-8G-L3 can be used with AC power supply 100-240 VAC, 50 - 60 Hz. Simply connect the power cord to the AC power connector located on the rear panel of the Switch and to AC power outlet. The Switch’s power supply will then adjust to the local power source automatically and may be started without having any or all LAN segment cables connected.
3. Connecting The Switch This chapter describes how to connect the VH-8G-L3 to your Ethernet network. Switch to End Node A PC can be connected to the Switch via a fiber optic cable. The PC can be connected to any of the eight ports of the Switch. Figure 3-1. Example of the Switch connected to a PC or Workstation The LED indicators for the port the end node is connected to are lit according to the capabilities of the NIC.

Appendix B. Flow Control Flow control is a mechanism that allows you to protect the switch from overload conditions and to keep additional traffic off the network when excessive congestion will result. Flow Control for Half- and Full-Duplex Applications Each port of the switch has a transmit queue which buffers frames to be sent out on that port.
