3. Select the target switch, VLAN, or port from the Target Context list. Target contexts and
spanning tree options at the product, VLAN, or port level are listed in Table 101 .
4. Select the type of spanning tree protocol from the Spanning Tree list.
5. Select the Enable check box if you want to enable the protocol you selected.
6. Enter a value in the Priority field to identify the root bridge in a spanning tree (instance of STP).
The bridge with the lowest value has the highest priority and is the root. A higher numerical
value means a lower priority; thus, the highest priority is 0. The values range from 0 through
61440 for a Fabric OS device; the default is 32768. The values range from 0 through 65535
for an IronWare device; the default is 32768.
7. Enter the number of seconds a bridge waits (the listen and learn period) before it begins to
forward data packets in the Forward Delay field. The values range from 4 through 30 seconds.
The default is 15 seconds.
8. Enter the number of seconds a root bridge waits before it sends the next BPDU in the Hello
Time field. The values range from 1 through 10 seconds. The default is 2 seconds.
9. Enter the number of seconds a bridge waits for a hello packet from the root bridge before
initiating a topology change in the Max Age field. The values range from 6 through 40 seconds.
The default is 20 seconds.
