stp port priority

Syntax
stp [ instance instance-id | vlan vlan-list ] port priority priority
undo stp [ instance instance-id | vlan vlan-list ] port priority
View
Ethernet interface view, port group view, Layer 2 aggregate interface view
Default level
2: System level
Parameters
instance instance-id: Sets the priority of the ports in a particular MSTI. The value of instance-id
ranges from 0 to 16, where 0 represents the CIST.
priority: Specifies a port priority, in the range of 0 to 240 in steps of 16 (as in 0, 16, 32).
vlan vlan-list: Specifies a VLAN list in the format of vlan-list = { vlan-id [ to vlan-id ] }&<1-10>, where
the vlan-id argument represents the VLAN ID, in the range of 1 to 4094, and &<1-10> indicates that
you can specify up to 10 VLAN IDs or VLAN ID ranges.
Description
Use stp port priority to set the priority of the ports.
Use undo stp port priority to restore the default.
By default, the port priority is 128.
Configured in Ethernet interface view, the setting takes effect only on the interface.
Configured in port group view, the setting takes effect on all ports in the port group.
Configured in Layer 2 aggregate interface view, the setting takes effect only on the aggregate
interface.
Configured on a member port in an aggregation group, the setting takes effect only after the port
leaves the aggregation group.
To set the priority of an MSTP port in a specific MSTI, use this command with the MSTI specified. To
set the priority of a PVST port in a specific VLAN or multiple VLANs, use this command with a VLAN
list specified. To set the priority of an MSTP port in the CIST or an STP/RSTP port, use this command
without specifying any MSTI and VLAN.
Port priority affects the role of a port in a spanning tree.
The smaller the value, the higher the port priority. If all ports on your device use the same priority
value, the port priority depends on the port index. The smaller the index, the higher the priority.
