HPswitch(config)# spanning-tree maximum-age 30 hello-time 3
Executing spanning-tree alone enables STP. Executing spanning-tree with one
or more of the above "STP Operating Parameters" does not enable STP. It only
configures the STP parameters (regardless of whether STP is actually running
(enabled) on the switch).
Syntax:
spanning-tree
priority < 0 - 65355 >
maximum-age < 6 - 40 seconds >
hello-time < 1 - 10 seconds >
forward-delay < 4 - 30 seconds >
Default: Refer to table 6-3, above.
For example, to configure a maximum-age of 30 seconds and a hello-time of 3
seconds for STP:
Reconfiguring Per-Port STP Operation on the Switch.
Syntax: spanning-tree < port-list > path-cost < 1 - 65535 > priority < 0 - 255 > mode
< norm | fast >
Enables STP (if not already enabled) and configures the per-
port parameters listed in table 6-4.

Range Function
1 - 65535 Assigns an individual port cost that the switch uses
to determine which ports are the forwarding ports.
0 - 255 Used by STP to determine the port(s) to use for
forwarding. The port with the lowest number has
the highest priority.
norm Specifies whether a port progresses through the
- or -
listening, learning, and forwarding (or blocking)
fast states ("norm" mode) or transitions directly to the
- or -
forwarding state ("fast" mode).
