Figure 7- 29. STP Port Settings window

In addition to setting Spanning Tree parameters for use on the switch level, the Switch allows for the

configuration of groups of ports, each port-group of which will have its own spanning tree, and will

require some of its own configuration settings. An STP Group will use the switch-level parameters

entered above, with the addition of Port Priority and Port Cost. An STP Group spanning tree works in

the same way as the switch-level spanning tree, but the root bridge concept is replaced with a root port

concept. A root port is a port of the group that is elected based on port priority and port cost, to be the

connection to the network for the group. Redundant links will be blocked, just as redundant links are

blocked on the switch level. The STP on the switch level blocks redundant links between switches

(and similar network devices). The port level STP will block redundant links within an STP Group.

It is advisable to define an STP Group to correspond to a VLAN group of ports.

The following STP Port Settings fields can be set:

1 2 ... 109 110 111 112 113 114 115 116 117 118 119 ... 333 334
