Specifies the port priority of the port in the specified STPD (Spanning Tree Domain).
| stpd_name | Specifies an STPD name on the switch. |
| priority | Specifies a numerical port priority value. The range is 0 through 240 and is subject to the multiple of 16 restriction. |
| port_list | Specifies one or more ports or slots and ports. |
The default is 128.
If your STPD has the same name as another component, for example a VLAN (Virtual LAN), 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 (Spanning Tree Protocol) 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 port, you can make it more or less likely to become the root port or a designated port.
To preserve backward compatibility and to use ExtremeXOS 11.5 or earlier configurations, the existing configure stpd ports priority command is available in ExtremeXOS 11.6. If you have an ExtremeXOS 11.5 or earlier configuration, the switch interprets the port priority based on the 802.1D-1998 standard. If the switch reads a value that is not supported in ExtremeXOS 11.6, the switch rejects the entry. For example, if the switch reads the configure stpd ports priority 16 command from an ExtremeXOS 11.5 or earlier configuration, (which is equivalent to the command configure stpd ports priority 8 entered through CLI), the switch saves the value in the new ExtremeXOS 11.6 configuration as configure stpd ports port-priority 128.
A setting of 0 indicates the highest priority.
The range for the priority parameter is 0 through 240 and is subject to the multiple of 16 restriction.
The following command assigns a priority of 32 to slot 2, ports 1 through 5 in STPD s0:
configure stpd s0 ports port-priority 32 2:1-2:5
This command was first available in ExtremeXOS 11.6.
This command is available on the Summit X450-G2, X460-G2, X670-G2, X770, and ExtremeSwitching X440-G2, X620, X690, X870 series switches.
