端口针对不同业务限速，带宽保障

第一阶段调试（基础网络配置）：

SW1：

<H3C>sys

System View: return to User View with Ctrl+Z.

[H3C]sysname SW1

[SW1]vlan 10

[SW1-vlan10]quit

[SW1]int gi 1/0/1

[SW1-GigabitEthernet1/0/1]port link-type trunk

[SW1-GigabitEthernet1/0/1]undo port trunk permit vlan 1

[SW1-GigabitEthernet1/0/1]port trunk permit vlan 10

[SW1-GigabitEthernet1/0/1]quit

[SW1]int range gi 1/0/2 to gi 1/0/3

[SW1-if-range]port link-type access

[SW1-if-range]port access vlan 10
