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.

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.

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.

6640-3202
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.

IGMP (Internet Group Management Protocol)
The Lynx switch supports IGMP (Internet Group Management Protocol) Snooping based  on IGMP v1, IGMP v2 and IGMP v3. To enable IGMP Snooping, click Enable IGMP.
For more information on IGMP, please read the Whitepaper found on the enclosed Lynx CD or at the Westermo website.
Available options are:
Disable/Enable IGMP This option disables/enables IGMP.

(IGMP focal point) Auto mode enabled + Querier enabled: This unit can act as a Querier in the network. If 
more than one unit in the network is configured  with this setting, the unit with the lowest IP-address  will automatically be selected as Querier. If that  unit should fail, the unit with the second lowest  IP-address becomes the Querier, then the third low­est and so on.
Querier interval (seconds) Indicates the interval between two IGMP query 
packets. Four intervals are possible. 12, 30, 70 or 150  seconds.
Enable IGMP Fast Reconnect The IP multicast filter implementation is integrated 
with the Fast Reconfiguration of Network Topology  (FRNT) protocol. This means that the multicast  filters will be updated as fast the FRNT implementa­tion handles a topology change, i.e. approx. 20 ms.
Trunk Ports The IGMP Queriers will be forwarded on selected 
ports.
Click the "Apply" button to confirm changes made to the IGMP settings.   The unit needs to be restarted before changes can take affect.

SNMP (Simple Network Management Protocol)
The Lynx has support for SNMP v2c with a range of MIBs, which are listed and explained  in the Lynx White paper.
The Lynx MIB's are divided into groups allowing the SNMP manager to poll the SNMP  agents for information. 
For more information on SNMP and MIB's, please read the Whitepaper found on the enclosed Lynx CD or at the Westermo web page.
Available options are:
Disable/Enable SNMP This option disables/enables SNMP.

VLAN
The Lynx has support for VLAN, and each trunk port can be individually granted different  levels of access. In the VLAN Configuration each VLAN ID is named as a different colour.  The colour White is static and set as management VLAN with VLAN ID 1, this can not be  changed. 
All other predefined VLANs are fully manageable, and necessary settings are made in the 
VLAN Configuration.
For more information on VLAN, please read the Whitepaper found on the enclosed Lynx CD or at the Westermo web page.

MAC Filter
If the MAC filter is enabled, only approved MAC addresses will be granted access through  the switch. To approve MAC addresses, add them according to the methods below.
Note that this function should be used with care. An incorrect configuration  could result in total denied access, and a factory reset of the unit would then  be needed.
MAC addresses can be added to the MAC filter by different methods:
1) One by one by adding a single MAC address in the small input-box.   The MAC address should be typed in the standard format - e.g. 00:07:7c:12:34:56
2) As a range of addresses using an asterisk, *, as a wild card. E.g. 00:07:7c:12:34:**  This will allow addresses between 00:07:7c:12:34:00 to 00:07:7c:12:34:ff.
3) As a sequence of single MAC addresses divided by a semi colon.  Example: 00:07:7c:00:00:00;00:07:7c:00:01:00;00:07:7c:00:0*:**;00:07:7c:00:00:02;
MAC addresses can be added according to method 1 and method 2 in the sequence. Available options are:
17
6640-3202
Input-box small Input-box if a MAC address is added according to method 1) or 2)
Input-box large Input-box if a MAC address is added according to method 3) 
Click the "Apply" button to confirm changes made to the MAC filter settings. The unit  needs to be restarted before changes can take affect.
Note! Once the MAC filter has been enabled on a unit, the units own MAC address 
must be added to the MAC filter.

Backup & Restore
The configuration of the Lynx switch can be saved as a file to a PC. The file can then  be used to restore the configuration later on, or used to configure another switch with  identical configuration.
Available options are:
Backup To save current configuration, click Backup and save file 
to a suitable location.
Upload To load a saved configuration, insert path and filename 
into File path table or click Browse to browse the loca­tion of the saved file. When file path is valid, click Upload.
