Spanning Tree (Transparent Bridging) Filtering
The administrator can restrict certain nodes from using the Spanning Tree (transparent bridging) feature of the
RouteFinder. It is also possible to restrict the access only to a specific node.
Spanning Tree Algorithm is a protocol specified by the IEEE 802.1d standard for use by bridges to perform
bridging. Bridges implementing this protocol interact with each other so as to prevent bridging-loops in an
internetwork with redundant links to the same networks. This algorithm also allows for automatic use of
alternative routes (provided there are redundant paths to the destination) in case the original route is
unavilable for some reason.
Default Action
A received packet whose Ethernet source address or destination address is not found in the filtering database
will either be filtered or forwarded as set in this field. The default setting of this option is forward.
Filtering Entries List
This area lists the currently established Spanning Tree filters in the RouteFinder database. The first column
shows the type of filter (like filter on source address being equal or forward on destination address being
equal, etc.). The second column list the port on which the filter is applicable. The third column shows the
Ethernet MAC address for which we need the filtering.
Add
Chose this option to established a new filter in the filtering database.
Remove
Current selection in the filtering database list, if any, can be delected with this option.
Edit
Current selection in the filtering database list, if any, can be edited with this option.
