DES-3326 Layer 3 Switch Example Layer 3
Configuration Guide.
Model: DES-3326
Firmware Version 1.00B19
OS Supported: Windows 95, Windows 98, Windows 98SE, Windows Me,
Windows NT 4.0 and Windows 2000.
Introduction
This guide will help you to setup a routing function to operate between two
TCPIP networks. Its important to have the latest firmware installed in the
switch before embarking on the configuration. At the time of writing this
document the firmware release was 1.00B19. Please visit the UK ftp site for
the latest firmware releases.

Network Configuration
Fig 1. Network Configuration.
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 isno username and no password, simply press
return -return. You will be presented with the main menu options as shown in
fig 3.
Fig 3. Switch Main Menu
Select from the main menu 'Switch Settings'
Fig 4. Switch Settings Menu
From the switch settings menu select 'Switch Operating Mode'
Fig 5. Switch Operating Mode
Using the space bar change the operating mode from layer 2 to 'IP Routing,
support IEEE 802.1Q VLANs' as in fig 5. Apply the changes, the switch will
reboot. Reattach to the switch through HyperTerminal. Please note, you do
not need to change any of the configuration parameters in the 'Remote
management setup' leave them at there default settings, fig 6.

After you have completed the above. Proceed to the next stage of the
configuration, that is to configure the VLAN's.
Fig 7. Main Menu
From the main menu select 'VLAN's'
Fig 8. VLAN Menu
Select 'Configure 802.1Q Port Settings'. You will need to configure the port
VLAN ID (PVID) before configuring the 802.1Q VLAN's. The default PVID for
all ports is set to 1. For setting up VLAN's for the engineering department use
PVID=2, for sales use PVID=3 as shown in Fig. 9.
Fig 9. 802.1Q Port Settings
After the above is completed your ready to configure the 802.1Q VLAN's. Go
to the previous menu and select 'Edit 802.1.Q VLAN's'.
Fig 10. 802.1Q VLAN's
For the VID use the same number as used for the PVID previously. You will
need to leave the default VLAN as is, ie do not change the default VID. Use
the TAB key to cursor to the VID and enter '2', again use the TAB key to
cursor to VLAN name and enter an appropriate name. In this example we
have the first octet of the IP adress. Under the membership, 'Egress' the port
by selecting E. You will need to Egress all the port members of this VLAN. In
this example only ports 1 & 2 are members. In the Tagging section, select 'U'
for Untag. This is so because adapters connected to these ports may not be
Tag compliant. Repeat the procedure for the second subnet.
Your now ready to configure you layer 3 routing configuration within the
switch. From the main menu select layer 3 IP Networking, then select 'Setup
IP Interface'
Fig 11. Layer 3 IP Networking
Fig 12. IP Interface Setup
Once again in this example we have used the fist octet for the interface name.
The IP address is the IP address of the the switch in that particular subnet, we
have choosen 192.168.0.250 MASK 255.255.255.0. The VID is the PVID set
in the VLAN configuration previously done. After the config is applied, the
screen will show you the configuration as in fig 12.
Fig 13. Subnet 192 Config
Fig 14. Subnet 212 Config
Ensure all the configurations have been applied, check the IP interfaces
addresses. If all looks okay return to the main menu and save the
configuration.
Fig. 15 Save Configuration
How to Test the Configuration
To test the configuration, do a ping test from a PC on the192 subnet to a PC
on the 200 subnet. If succesful, the layer configuration is complete. If the ping
test produces a 'request timed out' check the configuration above more
carefully. You may need to perform a factory reset and re-config the switch.
