ACTIVATE STP
Syntax
activate stp
Parameters
None
Description
Use this command to designate STP as the active spanning tree on the
switch. Once you have selected STP, you can enable or disable it using
the ENABLE STP and DISABLE STP commands. A spanning tree protocol
is active on a switch only after you designate it as the active spanning
tree and enable it.
The default active spanning tree is RSTP. To determine which spanning
tree is the currently active spanning tree, use the SHOW SWITCH
command.
Note
Changing the active spanning tree protocol will reboot the switch.
Some network traffic may be lost.
When you activate STP, the management software displays a prompt
asking if you want to enable the spanning tree. If you select yes, the
management software activates STP, resets the switch, and, once the
reset process is completed, enables STP. If you select no, the
management software activates STP and resets the unit, but does not
enable STP. You might select the latter if you want to configure STP
parameters before enabling spanning tree.
Example
The following command designates STP as the active spanning tree:
activate stp
