STP Commands
ExtremeWare XOS 11.5 supports only the Summit X450 family of switches and the BlackDiamond 8800 series switch.
ExtremeWare XOS 11.5 Command Reference Guide
1200
configure stpd priority
configure stpd <stpd_name> priority <priority>
Description
Specifies the bridge priority of the STPD.
Syntax Description
Default
The default priority is 32,768.
Usage Guidelines
If your STPD has the same name as another component, for example a VLAN, Extreme Networks
recommends that you specify the identifying keyword as well as the name. If your STPD has a name
unique only to that STPD, the keyword
stpd
is optional.
You should not configure any STP parameters unless you have considerable knowledge and experience
with STP. The default STP parameters are adequate for most networks.
By changing the priority of the STPD, you can make it more or less likely to become the root bridge.
The range for the
<priority>
parameter is 0 through 65,535. A setting of 0 indicates the highest
priority.
For MSTP, the priority level increases or decreases in size by 4,096. To lower the numerical value of the
priority (which gives the priority a higher precedence), you subtract 4,096 from the default priority:
32,768 - 4,096 = 28,672. If you modify the priority by a value other than 4,096, the switch automatically
changes the priority to the lower priority value. For example, if you configure a priority of 31,000, the
switch automatically changes the priority to 28,672.
Example
The following command sets the bridge priority of
STPD1
to 16,384:
configure stpd stpd1 priority 16384
History

stpd_name
