8.2.2 General configuration

Start MSTP

When the system is started, the default configuration MSTP is closed。

The configuration process for starting MSTP is：

Switch#configure terminal

Switch(config)#spanning-tree mst enable

The command to close MSTP is：

Switch#configure terminal

Switch(config)#no spanning-tree mst

Configuration max-age

Configuring max-age is the configuration of all instances. Max-age is the number of seconds

when the switch waits for the configuration information of the spanning tree before triggering a

reconfiguration。

The default configuration is 20 seconds, and the configuration range is 6 to 40 seconds。

Configuration process：

Switch#configure terminal

Switch(config)#spanning-tree mst max-age <seconds>

Configuration max-hops

Max-hops is the number of hops specified before a BPDU is discarded in a domain。

The default value is 20, and the configuration range is 1 to 40。

Configuration process：

Switch#configure terminal

Switch(config)#spanning-tree mst max-hops <hop-count>

Configuration forward-time

Configuring forward-time is for all instances. Forward-time is the number of seconds that
