A ByteBlower server comes with one or more ByteBlower switches. These switches are configured in a specific way to work seamlessly with the server. Normally, this configuration should never by changed. However, the new VLAN functionality of ByteBlower requires a modification of this configuration.

This document will explain exactly how to do this on the (newer) 24 and 48 port SMC switches. This are switches looking like the one in the picture.

If you have another (older) type of ByteBlower switch, like a Transtec or Linksys switch, and you want to use VLAN functionality on your trunk interfaces, please contact us at support.byteblower@excentis.com.

Connecting to the switch

The switch is configured using its serialinterface called Console. For every switch that was shipped with your ByteBlower Server, a serial-to-RJ45 cable has been provided. Connect the switch to a desktop system using this cable.

Next, configure the serial port connection using a program of your choice (such as minicom for Linux or HyperTerminal or Putty for Windows). The serial connection settings are:

• Bitrate: 9600
• Parity bit setup: 8N1
• No software or hardware flow control

Once the serial terminal is synchronized to the connection (pressing random keys may speed up this process), a login prompt should appear. Login using admin/admin as credentials.

Configuring the switch

Once you are connected and logged in, you can start configuring the ByteBlower switch. To update the ByteBlower configuration, execute the commands below. The manual input is described in bold. Make sure you execute the commands exactly as described and in the correct order. The tab key can be used for auto-completion.

If you have a 24-port switch, execute the following commands:

Console#configure
Console(config)#dot1q-tunnel system-tunnel-control
Console(config)#interface ethernet 1/1-24
Console(config-if)#switchport dot1q-tunnel mode access
Console(config-if)#exit
Console(config)#interface ethernet 1/25
Console(config-if)#switchport dot1q-tunnel mode uplink
Console(config-if)#exit
Console(config)#exit
Console#

If you have a 48-port switch, execute the following commands:

Console#configure
Console(config)#dot1q-tunnel system-tunnel-control
Console(config)#interface ethernet 1/1-48
Console(config-if)#switchport dot1q-tunnel mode access
Console(config-if)#exit
Console(config)#interface ethernet 1/49
Console(config-if)#switchport dot1q-tunnel mode uplink
Console(config-if)#exit
Console(config)#exit
Console#

On both the 24- and 48 port switches, execute the following commands to save the new configuration:

Console#copy running-config startup-config
Startup configuration file name [startup1.cfg]: <press enter>
Write to FLASH Programming.
Write to FLASH finish.
Success.
Console#

Finally, reboot the switch by executing the following command.

Console#reload
System will be restarted. Continue <y/n>?

After reboot, verify the running configuration is correct. Execute the following command and compare the output with the printed configuration file in the next section.

Console#show running-config

Your switch is now successfully configured!

Updated configuration files

The output of the show running-config command should look like the files below. Make sure the bold items are present.
