instance-id
: Specifies the spanning tree instance ID, ranging from 0 to 48. The Instance
0 represents CIST.
port priority priority
: Specifies the port priority, ranging from 0 to 240 with a step length
of 16, e.g., 0, 16 and 32. By default, the port has a priority of 128 on every MSTI.
Description
Use the
stp interface instance port priority
command to configure the priority of the
specified port on the specified MSTI in system view.
Use the
undo stp interface instance port priority
command to restore the default
priority.
You may specify the
instance-id
parameter as 0 to configure CIST priority of the port.
The port priority has effect on the port role selection for the specified MSTI. A port can
be configured with different priorities on different MSTIs. Thus the traffic from different
VLANs can run over different physical links, thereby implementing the VLAN-based
load-balancing. MSTP will recalculate the port role and transit its state, upon the port
priority changes.
