Page 19: Introduction
The MES-2110 is an ideal solution for small networks where rapid growth can be expected in the near future. The MES-2110 can be used standalone for a group of heavy traffic users. You can connect computers and servers directly to the MES- 2110’s port or connect other switches to the MES-2110.

Sales) to the corporate backbone. It can alleviate bandwidth contention and eliminate server and network bottlenecks. All users that need high bandwidth can connect to high-speed department servers via the MES-2110. You can provide a super-fast uplink connection by using a Gigabit Ethernet/mini-GBIC port on the MES-2110.
Page 21: High Performance Switching Example
1.1.3 High Performance Switching Example The MES-2110 is ideal for connecting two networks that need high bandwidth. In the following example, use trunking to connect these two networks. Switching to higher-speed LANs such as ATM (Asynchronous Transmission Mode) is not feasible for most people due to the expense of replacing all existing Ethernet cables and adapter cards, restructuring your network and complex maintenance.

VLAN 1. Ports can belong to other VLAN groups too. Figure 4 Shared Server Using VLAN Example 1.1.5 Metro Ethernet The MES-2110 is ideal for connecting users to an Ethernet network that spans a metropolitan area. In the following example, the MES-2110 is one of many switches that connect users in the metropolitan area to the Internet.

• Command Line Interface. Line commands offer an alternative to the web configurator and in some cases are necessary to configure advanced features. See the CLI Reference Guide. • SNMP. The MES-2110 can be monitored by an SNMP manager. See on page 166.
Page 24: Good Habits For Managing The Mes-2110
Chapter 1 Introduction 1.3 Good Habits for Managing the MES-2110 Do the following things regularly to make the MES-2110 more secure and to manage the MES-2110 more effectively. • Change the password. Use a password that’s not easy to guess and that consists of different types of characters, such as numbers and letters.
Page 25: Hardware Installation And Connection
Note: For proper ventilation, allow at least 4 inches (10 cm) of clearance at the front and 3.4 inches (8 cm) at the back of the MES-2110. This is especially important for enclosed rack installations. 2.2 Desktop Installation Procedure Make sure the MES-2110 is clean and dry.
Page 26: Hardware Installation And Connection
2.3 Mounting the MES-2110 on a Rack The MES-2110 can be mounted on an EIA standard size, 19-inch rack or in a wiring closet with other equipment. Follow the steps below to mount your MES- 2110 on a standard EIA rack using a rack-mounting kit.
Page 27: Attaching The Mounting Brackets To The Mes-2110
• Make sure the rack will safely support the combined weight of all the equipment it contains. • Make sure the position of the MES-2110 does not make the rack unstable or top-heavy. Take all necessary precautions to anchor the rack securely before installing the unit.
Page 28: Mounting The Mes-2110 On A Rack
Chapter 2 Hardware Installation and Connection 2.3.3 Mounting the MES-2110 on a Rack Position a mounting bracket (that is already attached to the MES-2110) on one side of the rack, lining up the two screw holes on the bracket with the screw holes on the side of the rack.

3.1.3 Mini-GBIC Slots These are slots for mini-GBIC (Gigabit Interface Converter) transceivers. A transceiver is a single unit that houses a transmitter and a receiver. The MES-2110 does not come with transceivers. You must use transceivers that comply with the Small Form-factor Pluggable (SFP) Transceiver MultiSource Agreement (MSA).
Page 32: Transceiver Installation
Chapter 3 Hardware Overview You can change transceivers while the MES-2110 is operating. You can use different transceivers to connect to Ethernet switches with different types of fiber- optic or even copper cable connectors. To avoid possible eye injury, do not look into an operating fiber- optic module’s connectors.

H A P T E R 4.1 IGMP Snooping IGMP snooping allows a layer-2 device such as the MES-2110 to eavesdrop on IGMP-based data packets traversing the communications channel on layer-3. This allows it to determine which ports should specifically receive multicast traffic in order to prevent multicasting flooding across all of its ports.

Page 71: Loop Detection
Loop detection is designed to handle loop problems on the edge of your network. This can occur when a port is connected to a MES-2110 that is in a loop state. Loop state occurs as a result of human error. It happens when two ports on a switch are connected with the same cable.

P to switch B. Since switch B is in loop state, the probe frame P returns to port N on A. The MES-2110 then shuts down port N to ensure that the rest of the network is not affected by the switch in loop state.
Page 73 MES-2110 sends probe frames from this port to check if the switch it is connected to is in loop state. If the switch that this port is connected is in loop state the MES-2110 will shut down this port.

It checks IGMP frames passing through it, picks out the group registration information, and configures multicasting accordingly. IGMP snooping allows the MES-2110 to learn multicast groups without you having to manually configure them.

Page 128: Types Of Mvr Ports
Figure 57 MVR Network Example 17.4.1 Types of MVR Ports In MVR, a source port is a port on the MES-2110 that can send and receive multicast traffic in a multicast VLAN while a receiver port can only receive multicast traffic. Once configured, the MES-2110 maintains a forwarding table that matches the multicast stream to the associated multicast group.
Page 129: General Mvr Configuration
MES-2110. This maps the subscriber VLAN to the list of forwarding destinations for the specified multicast traffic. When the subscriber changes the channel or turns off the computer, an IGMP leave message is sent to the MES-2110 to leave the multicast group.

The MES-2110 does not turn on. None of the LEDs turn on. Make sure you are using the power adaptor or cord included with the MES-2110. Make sure the power adaptor or cord is connected to the MES-2110 and plugged in to an appropriate power source.
Page 208: Mes-2110 Access And Login
Check the hardware connections. See Inspect your cables for damage. Contact the vendor to replace any damaged cables. Disconnect and re-connect the power adaptor or cord to the MES-2110. If the problem continues, contact the vendor. 24.2 MES-2110 Access and Login I forgot the IP address for the MES-2110.
Page 209 Make sure your Internet browser does not block pop-up windows and has JavaScripts and Java enabled. Make sure your computer is in the same subnet as the MES-2110. (If you know that there are routers between your computer and the MES-2110, skip this step.) Reset the device to its factory defaults, and try to access the MES-2110 with the default IP address.
Page 210 This will allow you to correct any mistakes you may have made in the Web Configurator. I can see the Login screen, but I cannot log in to the MES-2110. Make sure you have entered the user name and password correctly. The default user name is admin, and the default password is 1234.

• Try making your changes through the MES-2110’s command line interface (Chapter 23 on page changes permanent. • Power off the MES-2110, then power it back on and make your changes afresh. • Reset the MES-2110 to its factory default settings • If the problem continues, contact the vendor.
Page 212 • To see which commands are available to you while using the command line interface, type ? and press [ENTER]. I enabled ARP inspection on my MES-2110 but it doesn’t seem to be working. It is recommended you enable DHCP snooping at least one day before you enable ARP inspection so that the MES-2110 has enough time to build the binding table.
