Example
# Configure the link connecting GigabitEthernet 1/0/3 as a point-to-point link.

stp port priority

Description
Use the stp port priority command to set the priority of the ports.
Use the undo stp port priority command 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.

Default level
2: System level
Parameters
instance instance-id: Sets the priority of the ports in a particular MSTI. The value of instance-id is in the
range of 0 to 31, 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- 1 0>, where the
vlan-id parameter represents the VLAN ID, in the range of 1 to 4094, and &<1- 1 0> indicates that you can
specify up to 10 VLAN IDs or VLAN ID ranges.
