Parameters

instance instance-list: Sets the priority of the port in the MSTIs that are specified by an instance list. They

are in the format of instance-list = { instance-id [ to instance-id ] }&<1-10>, where &<1-10> indicates that

you can specify up to 10 instances or instance ranges. The value range for the instance-id argument is

0 to 4094, and the value 0 represents the CIST.

vlan vlan-id-list: Sets the priority of the port in the VLANs specified by a VLAN ID list. They are in the

format of vlan-id-list = { vlan-id [ to vlan-id ] }&<1-10>, where &<1-10> indicates that you can specify up

to 10 vlan-id [ to vlan-id ] parameters. The value range for the vlan-id argument is 1 to 4094.

priority: Specifies the port priority in the range of 0 to 240 in increments of 16 (as in 0, 16, 32).

Usage guidelines

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.

When the setting is configured in Layer 2 Ethernet interface view, it takes effect on only the interface.

If you do not specify any MSTI or VLAN, this command configures the priority of the ports in the MSTP

CIST or in the STP or RSTP spanning tree.

Examples

# In MSTP mode, set the priority of port GigabitEthernet 2/1/3 to 16 in MSTI 2.

<Sysname> system-view

[Sysname] interface gigabitethernet 2/1/3

[Sysname-GigabitEthernet2/1/3] stp instance 2 port priority 16

# In PVST mode, set the priority of port GigabitEthernet 2/1/3 to 16 in VLAN 2.

<Sysname> system-view

[Sysname] interface gigabitethernet 2/1/3

[Sysname-GigabitEthernet2/1/3] stp vlan 2 port priority 16
