Configuring port speed on Huawei switches in non-negotiation mode

 Experimental requirements:

① Turn off the auto-negotiation function of the three switches and enable full-duplex mode

② Configure the port connecting SW2/SW3 to the PC to 10M rate, and configure the port connecting to SW1 to 100M mode; configure the SW1 port to 100M mode accordingly, and verify connectivity on the PC side.

SW1:

[SW1]interface g0/0/1
[SW1-GigabitEthernet0/0/1]undo negotiation auto   //关闭自协商功能
[SW1-GigabitEthernet0/0/1]duplex full             //开启全双工模式
[SW1-GigabitEthernet0/0/1]speed 100              //设置端口的速率为100Mbps

[SW1-GigabitEthernet0/0/1]interface g0/0/2
[SW1-GigabitEthernet0/0/2]undo negotiation auto
[SW1-GigabitEthernet0/0/2]duplex full
[SW1-GigabitEthernet0/0/2]speed 100
[SW1-GigabitEthernet0/0/2]q

SW2:

[SW2]interface g0/0/1
[SW2-GigabitEthernet0/0/1]undo negotiation auto
[SW2-GigabitEthernet0/0/1]duplex full
[SW2-GigabitEthernet0/0/1]speed 100
[SW2-GigabitEthernet0/0/1]Q

[SW2]interface g0/0/2	
[SW2-GigabitEthernet0/0/2]undo negotiation auto
[SW2-GigabitEthernet0/0/2]duplex full
[SW2-GigabitEthernet0/0/2]speed 10
[SW2-GigabitEthernet0/0/2]q

SW3:

[SW3]interface g0/0/1
[SW3-GigabitEthernet0/0/1]undo negotiation auto
[SW3-GigabitEthernet0/0/1]duplex full
[SW3-GigabitEthernet0/0/1]speed 100
[SW3-GigabitEthernet0/0/1]q

[SW3]interface g0/0/2
[SW3-GigabitEthernet0/0/2]undo negotiation auto
[SW3-GigabitEthernet0/0/2]duplex full
[SW3-GigabitEthernet0/0/2]speed 10
[SW3-GigabitEthernet0/0/2]q
