D-Link DES-3326 Configuration Manual - Configuration Procedure

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
