Tp-Link T1700G-28TQ V2 — понимание внутренней стоимости пути и конфигурации STP [225/354]

Превью страниц Страница 225 / 354

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.

portfast —— Enable/ Disable Edge Port. By default, it is disabled. The edge

port can transit its state from blocking to forwarding rapidly without waiting

for forward delay.

point-to-point —— The P2P link status, with auto, open and close options. By

default, the option is auto. If the two ports in the P2P link are root port or

designated port, they can transit their states to forwarding rapidly to reduce

the unnecessary forward delay.

Command Mode

Interface Configuration Mode (interface gigabitEthernet / interface range

gigabitEthernet / interface ten-gigabitEthernet / interface range

ten-gigabitEthernet / interface port-channel / interface range port-channel)

Privilege Requirement

Only Admin, Operator and Power User level users have access to these

commands.

Example

Enable the STP function of port 1, and configure the Port Priority as 64,

ExtPath Cost as 100, IntPath Cost as 100, and then enable Edge Port:

T1700G-28TQ(config)# interface gigabitEthernet 1/0/1

T1700G-28TQ(config-if)# spanning-tree common-config port-priority 64

ext-cost 100 int-cost 100 portfast enable point-to-point open

26.5 spanning-tree mode

Description

The spanning-tree mode command is used to configure the STP mode of the

switch. To return to the default configurations, please use no spanning-tree

mode command.

Syntax

spanning-tree mode { stp | rstp | mstp }

no spanning-tree mode
