Configuring The Switch Using The Console Interface; Before You Start; General Deployment Strategy - D-Link DGS-3308TG User Manual

ONFIGURING THE
Your 8 -port Gigabit Ethernet Layer 3 Switch supports a console management interface that allows you to set up and
control your Switch, either with an ordinary terminal (or terminal emulator), or over the network using the TCP/IP Telnet
protocol. You can use this facility to perform many basic network management functions. In addition, the console program
will allow you to configure the Switch for management using an SNMP-based network management system. This chapter
describes how to use the console interface to access the Switch, change its settings, and monitor its operation.
Notes are added where clarification is necessary.
Where there is a difference in the setup of the switch between its two operational modes ( L ayer 2 Only and IP
Routing), the sections are divided to correspond with the Switch operating mode that is applicable.
Note: IP Routing mode switch configuration settings that are saved to non-volatile RAM using Save
Changes from the Main Menu are retained in the Switch's memory when the operational
mode is changed. IP Routing mode settings are simply inactive when the Switch is in Layer 2
Only mode.

Before You Start

The DGS-3308 Layer 3 Switch supports a wide array of functions and gives great flexibility and increased network
performance by eliminating the routing bottleneck between the WAN or Internet and the Intranet. Its function in a network
can be thought of as a new generation of router that performs routing functions in hardware, rather than software. It is a
router that also has up to 8 independent Ethernet collision domains – each of which can be assigned an IP subnet.
This flexibility and rich feature set requires a bit of thought to arrive at a deployment strategy that will maximize the
potential of the DGS-3308.

General Deployment Strategy

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. See Chapter 5, "Switch Management
Concepts" section titled IP Addressing and Subnetting for more information.
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.
