D-Link DES-3326 Configuration Guide - Page 2

An illustration of a typical layer 3 application is shown in fig 1. above. Two departments are segmented using layer 3 routing protocol rather than segmented at the MAC layer. The engineering department is on ports 1 & 2. The sales department is on ports 17 to 24. Fig 2. Mix of Layer 2 & Layer 3 The example configuration can be further extended to include both layer 2 & 3 switches as shown in fig 2. The configuration is complete if PC1 can ping PC2. The DES-3326 thus has achieved the act of routing between the 2 subnets. For the purpose of this document, fig 1. above will be the reference configuration. Fig 2. is an illustration of what can be configured if layer 2 switches also exist in your network. Configuration Procedure Before you begin the layer 3 configuration, you will need to change the operating mode of the switch from layer 2 to layer 3. The default setting for the switch is layer 2. To do this, attach to the switch through its RS232 console port with HyperTerminal and login onto the switch. The default username and password is no username and no password, simply press
