准备阶段

技术背景

VLAN虽然可以实现报文之间的二层隔离，但只通过VLAN实现报文二层隔离，会浪费有限的VLAN资源。所以端口隔离用于在VLAN内隔离以太网端口.

组网需求

一台交换机模拟接入设备，为了隔离不同接口业务同时节省VLAN资源使用端口隔离功能，将接口GE1/0/1~GE1/0/2模拟为某公司A部门，将接口GE1/0/3模拟为某公司B部门，两部门之间二层隔离。

实验拓扑

配置流程

配置IP地址

每台PC依次设置IP地址为192.168.0.X X随设备编号而改变。

配置隔离族之前连通性测试：

### PC4
<H3C>ping 192.168.0.5
Ping 192.168.0.5 (192.168.0.5): 56 data bytes, press CTRL_C to break

<H3C>ping 192.168.0.6
Ping 192.168.0.6 (192.168.0.6): 56 data bytes, press CTRL_C to break

端口隔离配置：

SW3

<H3C>system-view 
[H3C]hostname SW3
# 创建VLAN 10 将GigabitEthernet 1/0/1 ~ GigabitEthernet 1/0/3 加入到该VLAN下
[SW3]vlan 10
[SW3-vlan10]port g1/0/1 to g1/0/3
[SW3-vlan10]quit

# 创建聚合组并将GigabitEthernet 1/0/1、GigabitEthernet 1/0/2 加入到聚合组1
# GigabitEthernet 1/0/3 加入到聚合组2.
[SW3]port-isolate group  1
[SW3]port-isolate group  2
[SW3]int ran g1/0/1 t g1/0/2
[SW3-if-range]port-isolate enable  group  1
[SW3-if-range]int g1/0/3
[SW3-GigabitEthernet1/0/3]port-isolate enable  group  2
[SW3-GigabitEthernet1/0/3]quit
