16.4 Rapid Spanning Tree Protocol Status

Use this screen to look at the status of RSTP on the switch. See
background information about RSTP. To open this screen, click Advanced Application >
Spanning Tree Protocol.
This screen is only available after you activate RSTP on the switch.

DESCRIPTION
This is the maximum time (in seconds) a 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. The allowed range is 4 to 30
seconds.
As a general rule:
Note: 2 * (Forward Delay - 1) >= Max Age >= 2 * (Hello Time + 1)
Select the slot at whose settings you want to look.
This field displays the slot number and port number.
Settings in this row apply to all ports.
Use this row only if you want to make some settings the same for all ports. Use this
row first to set the common settings and then make adjustments on a port-by-port
basis.
Note: Changes in this row are copied to all the ports as soon as you
make them.
Select this check box to activate RSTP on this port.
Configure the priority for each port here.
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. The
allowed range is between 0 and 255.
Path cost is the cost of transmitting a frame on to a LAN through that port. It is
assigned according to the speed of the bridge. The slower the media, the higher
the cost. See Table 22 on page 96
Click Apply to save your changes to the switch's run-time memory. The switch
loses these changes if it is turned off or loses power, so use the Save link on the
top navigation panel to save your changes to the non-volatile memory when you
are done configuring.
Click Cancel to reset the fields.
