R2511-HP MSR Router Series Layer 2 - LAN Switching Command Reference(V5)

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.
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.
