H3C stp默认没启用
启用stp后，若某端口需要快速转发,则需要:
stp edged-port enable
Configuring the Current Port as an Edge Port
Edge ports are ports that neither directly connects to other switches nor indirectly connects to other switches through network segments. After a port is configured as an edge port, the rapid transition mechanism is applicable to the port. That is, when the port changes from the blocking state to the forwarding state, it does not have to wait for a delay.
You can configure a port as an edge port in one of the following two ways.
Configure a port as an edge port in system view
Follow these steps to configure a port as an edge port in system view:
To do... | Use the command... | Remarks |
Enter system view | system-view | — |
Configure the specified ports as edge ports | stp interface interface-listedged-port enable | Required By default, all the Ethernet ports of a switch are non-edge ports. |
Configure a port as an edge port in Ethernet port view
Follow these steps to configure a port as an edge port in Ethernet port view:
To do... | Use the command... | Remarks |
Enter system view | system-view | — |
Enter Ethernet port view | interface interface-type interface-number | — |
Configure the port as an edge port | stp edged-port enable | Required By default, all the Ethernet ports of a switch are non-edge ports. |
On a switch with BPDU guard disabled, an edge port becomes a non-edge port again once it receives a BPDU from another port.
You are recommended to configure the Ethernet ports connected directly to terminals as edge ports and enable the BPDU guard function at the same time. This not only enables these ports to turn to the forwarding state rapidly but also secures your network.
Configuration example
# Configure GigabitEthernet 1/0/1 as an edge port.
1) Configure GigabitEthernet 1/0/1 as an edge port in system view
<Sysname> system-view
[Sysname] stp interface GigabitEthernet 1/0/1 edged-port enable
2) Configure GigabitEthernet 1/0/1 as an edge port in Ethernet port view
[Sysname] interface GigabitEthernet 1/0/1
[Sysname-GigabitEthernet1/0/1] stp edged-port enable
