states when the switch is the root bridge.
The range is 4 through 30. Default setting is 15.
configure stpd <stpd_name> hellotime
<value>
Specifies the time delay (in seconds) between

when it is the root bridge.
The range is 1 through 10. Default setting is 2.
configure stpd <stpd_name> maxage
<value>
Specifies maximum age of BPDU in this STPD.
The range is 6 through 40. Default setting is 20.

to 2 x (Hello Time + 1) and less than, or equal
to 2 x (Forward Delay –1).
configure stpd <stpd_name> port cost
<value> <portlist>
Specifies the path cost of the port in this STPD.
The range is 1 through 65,535. The switch
automatically assigns a default path cost based

Specifies the priority of the port in this STPD.
By changing the port priority, you can make it
more or less likely to become the Root Port.
The range is 0 through 31. Default setting is 16.
A setting of 0 indicates the lowest priority.
configure stpd <stpd_name> priority
