Parameters
configname
Specifies the name of the MST region that the switch belongs to.
The name must be up to 32 alphanumeric characters including an
underscore (_). The default value is the MAC address of the
switch.
revisionlevel
Specifies the revision of the MST region that the switch belongs to.
The range is 0 to 65535. The default value is 0.
maxhops
Specifies the maximum number of hops for a BPDU to be
forwarded in the MST region before a BPDU is discarded. The
default value is 20.
maxage
Specifies the maximum aging time of BPDUs in seconds, The
maxage is the length of time the switch holds a configuration BPDU
before discarding it and attempting a reconfiguration. The range is
6 to 40 seconds. The default is 20 seconds.
The value for the maxage parameter must be greater than
(2 x (hellotime +1)) and less than (2 x (forwarddelay -1)).
hellotime
Specifies the time interval, in seconds, between configuration
messages the root bridge sends. The range is 1 to 10 seconds.
The default is 2 seconds.
forwarddelay
Specifies the forward delay time in seconds. The forward delay
time is the length of time that a port waits before changing the STP
state from learning and listening to forwarding. The range is 4 to 30
seconds. The default is 15 seconds. This parameter effects only
the ports operating in the STP compatible mode.
