Chapter 47 Configuration Mode Commands
=Specifies the maximum time (in seconds) the Switch will wait before changing states. This delay is required because every Switch must receive information about topology changes before it starts to forward frames. In addition, each port needs time to listen for conflicting information that would make it return to a blocking state; otherwise, temporary data loops might result.
=Enables STP on the specified ports.
Specifies the cost of transmitting a frame on to a LAN through that port. It is assigned according to the speed of the bridge.
=Specifies the priority for each port.
Priority decides which port should be disabled when more than one port forms a loop in a Switch. Ports with a higher priority numeric value are disabled first.
= Specifies which STP configuration these ports will participate | |
treeIndex | in. (mrstp command only). |
An example using
•Enable STP on the Switch.
•Set the bridge priority of the Switch to 0.
•Set the Hello Time to 4, Maximum Age to 20 and Forward Delay to 15 on the Switch.
•Enable STP on port 5 with a path cost of 150.
•Set the priority for port 5 to 20.
