ONFIGURING
This section shows you how to configure MAC layer bridging information for the site template. The
screen below shows a basic MAC layer bridging configuration.
Note:
The default values are suitable for most configurations.
1.
For sites using MAC layer bridging, make sure Enable is checked as shown above. All other
bridging parameters will then take effect.
2.
Enter the Bridge Age Time (in seconds). This is the amount of time a bridge will keep a MAC
address it learns before that address expires. The default value is 300 seconds. This parameter
is available for systems with 1 or 2 LAN ports.
3.
Select the Bridging Mode. This allows you to determine the forwarding method that the bridge
uses to distribute LAN packets to the remote sites and to the LAN ports of the system. Possible
modes of operation are Unrestricted and Restricted. The default is unrestricted. In general, the
unrestricted mode forwards all packets, whereas the restricted mode discards all packets.
4.
If you have a system with 2 LAN ports, you can make use of all Spanning Tree Protocol
parameters. First, enable Spanning Tree (click on Spanning Tree and a check will appear in the
box adjacent to it). Next, define the Spanning Tree parameters.
a.
Bridge Priority: The configured priority for this system.
b. Bridge Max Age: The configured maximum age-time (in seconds) for this system when the
system is the root bridge.
