CONFIGURING THE SWITCH USING THE CONSOLE INTERFACE

The DES-3326 supports a console management interface that allows the user to connect to the switch’s management agent via a serial port and a terminal or a computer running a terminal emulation program. The console can also be used over the network using the TCP/IP Telnet protocol. The console program can be used to configure the switch to use an SNMP-based network management software over the network.

This chapter describes how to use the console interface to access the switch, change its settings, and monitor its operation.

Switch configuration settings that are saved to non-volatile RAM using Save Changes from the Main Menu are retained in the switch’s memory, and are reloaded when the switch is rebooted.

Before You Start

The DES-3326 supports a wide array of functions and gives great flexibility and increased network performance by eliminating the routing bottleneck between the WAN and the intranet. Its function in a network can be thought of as a new generation of wire-speed router that performs routing functions in hardware, rather than in software.

General Deployment Strategy

The DES-3326 has many automatic features to detect the network topology and adapt to changes in this topology, but it is recommended that a network scheme be developed and entered statically into the DES-3326.

1.Determine how the network would be best segmented. This is probably done using VLANs in an existing layer 2 switched network.

2.Develop an IP addressing scheme. This involves allocating a block of IP addresses to each network segment. Each network subnet is then assigned a network address and a subnet mask.

3.Determine which network resources must be shared by the subnets. Shared resources may be connected directly to the Layer 3 switch, if need be. Static routes to each of the shared resources should be determined.

4.Determine how each subnet will communicate with the WAN or Internet. Again, static routes should be determined and default gateways identified.

5.Develop a security scheme. Some subnets on the network need more security or should be isolated from the other subnets. IP or MAC filtering can be used. Also, one or more VLANs on the Layer 3 switch can be configured without an IP subnet – in which case, these VLANs will
