Parameters
instance instance-list: Specifies a space-separated list of up to 10 MSTI items. Each item specifies
an MSTI or a range of MSTIs in the form of instance-id1 [ to instance-id2 ]. The value for instance-id2
must be equal to or greater than the value for instance-id1. The value range for the instance-id
argument is 0 to 4094, and the value 0 represents the CIST.
vlan vlan-id-list: Specifies a space-separated list of up to 10 VLAN items. Each item specifies a
VLAN or a range of VLANs in the form of vlan-id1 [ to vlan-id2 ]. The value for vlan-id2 must be equal
to or greater than the value for vlan-id1. 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 only on that
interface.
When the setting is configured in Layer 2 aggregate interface view, it takes effect only on the
aggregate interface.
When the setting is configured on a member port in an aggregation group, it takes effect only after
the port leaves the aggregation group.
If you do not specify an 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 1/0/3 to 16 in MSTI 2.
<Sysname> system-view
[Sysname] interface gigabitethernet 1/0/3
[Sysname-GigabitEthernet1/0/3] stp instance 2 port priority 16
# In PVST mode, set the priority of port GigabitEthernet 1/0/3 to 16 in VLAN 2.
<Sysname> system-view
[Sysname] interface gigabitethernet 1/0/3
[Sysname-GigabitEthernet1/0/3] stp vlan 2 port priority 16
