TP-Link JetStream T3700G-52TQ - Spanning-Tree Common-Config

T3700G-52TQ
JetStream 52-Port Gigabit Stackable L3 Managed Switch CLI Guide
Example
Enable the STP function for Gigabit Ethernet port 1/0/2:
T3700G-52TQ(config)#interface gigabitEthernet 1/0/2
T3700G-52TQ(config-if)#spanning-tree
30.3 spanning-tree common-config
Description
The spanning-tree common-config command is used to configure the
parameters of the ports for comparison in the CIST and the common
parameters of all instances. To return to the default configuration, please use
no spanning-tree common-config command. CIST (Common and Internal
Spanning Tree) is the spanning tree in a switched network, connecting all
devices in the network.
Syntax
spanning-tree common-config [port-priority priority ] [ext-cost ext-cost ]
[int-cost
int-cost ] [portfast {enable | disable}] [point-to-point {auto | open |
close}]
no spanning-tree common-config
Parameter
priority —— Port Priority, which must be multiple of 16 ranging from 0 to 240.
By default, the port priority is 128. Port Priority is an important criterion on
determining if the port connected to this port will be chosen as the root port.
In the same condition, the port with the highest priority will be chosen as the
root port. The lower value has the higher priority.
ext-cost
—— External Path Cost, which is used to choose the path and
calculate the path costs of ports in different MST regions. It is an important
criterion on determining the root port. The lower value has the higher priority.
It ranges from o to 2000000. By default, it is 0 which is mean auto.
int-cost —— Internal Path Cost, which is used to choose the path and
calculate the path costs of ports in an MST region. It is an important criterion
on determining the root port. The lower value has the higher priority. By
default, it is automatic. It ranges from o to 2000000. By default, it is 0 which is
mean auto.
