Automatically
requests its IP address from a DHCP server which assigns the IP Address
automatically. For more information, refer to section 3.21 - “DHCP Server
Configuration”, Default is unchecked.
IP Address
Bridge Mode -
The IP address of the WI-MOD-E module. Both wired
(Ethernet Interface) port and wireless (Wireless Interface) ports will take
on this address.
Router Mode –
Separate IP addresses are required for each interface. IP
addresses must be different.
IP Subnet Mask
The IP network mask of the WI-MOD-E module. This should be set to
appropriate subnet mask for your system (Typically 255.255.255.0). In
Router mode each interface will have its own Netmask.
Default Gateway
This is the address that the device will use to forward messages to remote
hosts that are not connected to any of the local bridged network (Ethernet
or Wireless). This is only required if the wired LAN has a Gateway unit
which connects to devices beyond the LAN - for example, Internet access.
If there is no Gateway on the LAN, set to the same address as the Access
Point - that is, the “Ethernet IP Address” below. Refer to section 3.18 -
“Routing” for more information.
Save Changes
Save changes to non-volatile memory. The module will need to be
restarted before the changes take effect.
Save Changes and Reset.
Save settings to non-volatile memory, and reboot WI-MOD-E. Once the
module has completed the reboot sequence, all changes are in effect.
3.5 - Spanning Tree Algorithm
The bridge “Spanning Tree Protocol” function was introduced to handle network loops and provide redundant paths in
networks. To enable tick the STP box on any “WDS Connections” you have configured on the “Repeaters” configuration
page.
For example, consider the network below with a redundant wireless link. If the bridge Spanning Tree Protocol is enabled,
one of the two wireless links will be disabled - that is, all wireless data will be transferred by one link only. If the active link
fails, the other link will automatically start transferring the wireless data. The Spanning Tree Protocol implemented is IEEE
802.1d compatible. The algorithm forms a loop-free network by blocking traffic between redundant links in the network.
These blocked links are placed in a standby condition, and may be automatically enabled to repair the network if another
link is lost.
