configure stpd priority
Specifies the bridge priority of the STPD.
|stpd_name||Specifies an STPD name on the switch.|
|priority||Specifies the bridge priority
of the STPD. The range is 0 through 61,440.
The default priority is 32,768.
If your STPD has the same name as another component, for example a VLAN, we recommend 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.
The range for the priority parameter is 0 through 61,440. If the bridge priority mode is configured as dot1d and the protocol mode is configured as dot1w, then value can be configured in increments of 1. If the bridge priority mode is configured as dot1t and the protocol mode is configured as dot1w, then priority value can be configured in increments of 4,096. A setting of 0 indicates the highest priority.
If you have an ExtremeXOS 11.5 or earlier configuration that contains an STP or RSTP bridge priority that is not a multiple of 4,096, the switch rejects the entry and the bridge priority returns to the default value. The MSTP implementation already uses multiples of 4,096 to determine the bridge priority.
For example, 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 rejects the entry.
ExtremeXOS 11.5 and Earlier
If you have switches running ExtremeXOS 11.5 and earlier, the priority range is different than switches running ExtremeXOS 11.6 and later.
The range for the priority parameter is 0 through 65,535. A setting of 0 indicates the highest priority.
The following command sets the bridge priority of STPD1 to 16,384:
configure stpd stpd1 priority 16384
This command was first available in ExtremeXOS 10.1.
The priority range and behavior was updated based on support for the 802.1D-2004 standard in ExtremeXOS 11.6.
This command is available on ExtremeSwitching X435, X440-G2, X450-G2, X460-G2, X465, X590, X620, and X695 series switches.
