17.3.4 Configuring Switch Priority
The setting of the device priority concerns with which device is the root of the whole network,
as well as the topology of the whole network. It is recommended that administrators set the
core device with higher priority (smaller value), which will facilitate the stability of the whole
network. You can assign different device priorities for different instances, by which various
instances can run separate spanning tree protocol. Only the priority of CIST (Instance 0) is
related to the devices between different regions.
As mentioned in Bridge ID, there are 16 values for the priority, and all of them are multiples
of 4096, which are 0, 4096, 8192, 12288, 16384, 20480, 24576, 28672, 32768, 36864,
40960, 45056, 49152, 53248, 57344, and 61440. The default value is 32768.
In the privileged mode, perform these steps to configure the device priority:
Command
Function
DGS-3610# configure terminal
Enter the global configuration mode.
DGS-3610(config)# spanning-tree
[mst instance-id] priority priority
For the configuration of the device priority for different
instances, it will configure the instance 0 if you don‘t add
the instance parameters.
instance-id, whose range is 0-64.
priority, whose value range is 0 – 61440 and is increasing
by the integral multiple of 4096, 32768 by default.
DGS-3610(config)# end
Return to the privileged EXEC mode.
DGS-3610# show running-config
Check the configuration entries.
DGS-3610# copy running-config
startup-config
Save the configuration.
If you want to restore the default value, use the global configuration command no
spanning-tree mst instance-id priority to set.
17.3.5 Configuring Port Priority
When two ports are connected to the shared medium, the device will select one port with the
higher priority (smaller value) to enter the forwarding status, and one with lower priority
(greater value) to enter the discarding status. If two ports possess the same priority, the port
