Accessing and Using the Web Interface

To access to all possible settings, the Lynx switch should be configured via the onboard 
web based configuration tool. This application note describes the  web interface on the 
Lynx 1xx/4xx and Lynx 1xxx and how to use it. It is important that the unit has the 
latest firmware, which can be downloaded from Westermo website. All Lynx units with 
firmware 3.0 or later can  be configured through the web interface. If the unit has to be 
updated, please read the release note on upgrading Lynx before proceeding.

Firmware release note on upgrading the lynx is found at:

Accessing the Lynx Web Interface

The Lynx can easily be configured via the onboard Web based configuration interface or 
by using the Westermo IP Configuration utility.

From the IP Configuration utility a web browser can automatically be launched onto any 
desired switch in the same subnet, and a login box similar to figure 3 will be displayed.

Figure 3

Enter the following login details:

•  User name: admin 

•  Password: westermo
Note! This is the default login, but once logged in the administrator password can be

changed. Default login will not work if the admin password has been changed.

Note! This is the default password for all Lynx switches with Firmware 3.13 or later. For 

Lynx switches with older Firmware the default password is: otn

Note! Information on supported software are found in the Firmware Release Note.

Lynx Web Interface Structure

The administrator start page will be displayed and show a brief summary of the unit. It 
will be similar to figure 4. The menu bar is divided into a main menu, which is the top 
row tab, and a sub-menu, which is directly under the main menu, figure 5. The main menu 
tabs are used to select a group of pages, and the sub-menu is used to select a page within 
that group. Directly under the menu bar the content of the page will be displayed.

Configuration

Network (IP)

The Lynx switch IP-address can individually be changed via the Web Interface, another 
option is  DHCP.  These settings can be configured in the Network (IP) Settings.

MAC The Lynx switch MAC-address (can not be changed)

IP If it is desired to change the Lynx switch IP address, enter the new 

IP address and netmask. Once the changes have been applied, the IP 
address of the Lynx switch will change. The unit does not need to 
reboot after changes to the Network (IP) Settings.

Netmask The subnet netmask of the network. 

Gateway The address of the gateway in the network.

Enable DHCP Enables DHCP protocol on the Lynx switch

Click the "Apply"  button to confirm changes made to the Network (IP) Settings.

Note! If you are not sure about the settings – consult your network administrator.

Identity

The Lynx switch identity can be changed via the Web Interface.  
These settings can be configured in the Identity Settings.

Available options are:

Hostname Set desired hostname for the Lynx switch. Accepted characters are 0-9, 

a-z, A-Z, _ (underscore) and - (minus).

Location Set desired location for the Lynx switch. Accepted characters are 0-9, a-z, 

A-Z, _ (underscore) and - (minus).

Click the "Apply"  button to confirm changes made to the Identity Settings.

Redundancy protocol – FRNT

The Lynx switch supports the redundancy protocol FRNT (Fast Re-configuration of 
Network Topology, FRNT version 0).

For more information on FRNT, please read the Whitepaper found on the enclosed Lynx CD or
at the Westermo website.

Available options are:

Focal point If this unit should be the Focal Point, tick the check box. 

If this unit should act as a member in the ring, leave the check box 
unticked.

FRNT port 1 Selection of redundant port for FRNT

FRNT port 2 Selection of redundant port for FRNT

Disable FRNT This option disables FRNT.

Click the "Apply" button to confirm changes made to the Redundancy Protocol settings.   
The unit needs to be restarted before changes can take affect.

Note! Only one unit in a redundant ring using FRNT can be set as Focal Point.
Note! If the redundant ring is created with copper cables, selected FRNT ports

should be 5 and 6.

Redundancy protocol – RSTP

The Lynx switch support the Rapid Spanning Tree Protocol (RSTP) according to 
IEEE802.1w with fallback to the Spanning Tree Protocol (STP - IEEE802.1D).   
The STP fallback feature means that the Lynx switches can be used together  
with switches that only have support for STP.

For more information on RSTP, please read the Whitepaper found on the enclosed Lynx CD
or at the Westermo website.

Available options are:

Bridge Prio The switch with the lowest priority will become the root switch.

Dynamic  Dynamic trunking is enabled when RSTP is used in a VLAN to 

eliminate failure 

Trunking  due to an incorrectly configured VLAN. If every unit in the ring has 

enabled Dynamic trunking, all VLANs will be granted access on the 
ring.

Edge Ports Selection of edge ports for RSTP.

Disable RSTP This option disables RSTP.

Click the "Apply" button to confirm changes made to the Redundancy Protocol settings.  
The unit needs to be restarted before changes can take affect.

For more information on IGMP, please read the Whitepaper found on the enclosed Lynx CD
or at the Westermo website.

Available options are:

Enable Multicast Stopfilter Enable this option if the switch should deny unwant-

ed Multicast broadcasts.

Enable IGMP Automode Options according to possible combinations below:
