R3303-HP HSR6800 Routers Layer 2 - LAN Switching Command Reference

74
priority: Port priority, which is in the range of 0 to 240 in increments of 16 (as indicated by 0, 16, 32).
Usage guidelines
Configured in Ethernet interface view, the setting takes effect only on the interface.
Configured in port group view, the setting takes effect on all member 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 an MSTP port in the CIST or an STP or RSTP port, use this command without specifying any
MSTI.
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.
Examples
# In MSTP mode, set the priority of port GigabitEthernet 4/0/3 to 16 in MSTI 2.
<Sysname> system-view
[Sysname] interface GigabitEthernet 4/0/3
