value represents the priority of the bridge. It can be
one of the following values:
0, 4096, 8192, 12288, 16384, 20480, 24576,
28672,

no spanning-tree mstpinstance-idpriority
Resumes the bridge priority of the switch to the
default value.
instance-id means the number of the spanning tree
instance, ranging from 0 to 15.
19.2.3.7 Configuring STP Time Parameters
The following are STP time parameters:
 Hello Time:
The interval to send the configuration message to the designated port when the switch functions as the
network root.
 Forward Delay:
Time that the port needs when it changes from the Blocking state to the learning state and to the
forwarding state in STP mode.
 Max Age:
The maximum live period of the configuration information about the spanning tree.
To reduce the shock of the network topology, the following requirements for the time parameters must be
satisfied:
 2 x (fwd_delay - 1.0) >= max_age
 max_age >= (hello_time + 1) x 2
Command Purpose
spanning-tree mstp hello-timeseconds
Sets the parameter Hello Time.
The parameter seconds is the unit of Hello Time,
ranging from 1 to 10 seconds. Its default value is
two seconds.
no spanning-tree mstp hello-time Resumes Hello Time to the default value.
spanning-tree mstp forward-timeseconds
Sets the parameter Forward Delay.
The parameter seconds is the unit of Forward
Delay, ranging from 4 to 30 seconds. Its default
value is 15 seconds.
no spanning-tree mstp forward-time Resumes Forward Delay to the default value.
spanning-tree mstp max-ageseconds
Sets the parameter Max Age.
The parameter seconds is the unit of Max Age,
