交换机端口在配置vlan过程中，每个端口都需要配置link-type、vlan-tag，如果不批量配置，会非常麻烦；
华为交换机可以通过端口组配置解决这个问题。
1、创建端口组名称：
port-group name 命名用来创建Port Group名称
undo port-group name命令用来删除Port Group名称
dis port-group命令用来查看端口组成员接口信息
<L2-SW-2>sys
Enter system view, return user view with Ctrl+Z.
[L2-SW-2]port-group all_access_vlan_1091
[L2-SW-2-port-group-all_access_vlan_1091]2、在端口组里添加成员：
group-member命令将指定的以太网接口添加到端口组中。
<L2-SW-2>sys
Enter system view, return user view with Ctrl+Z.
[L2-SW-2]port-group all_access_vlan_1091
[L2-SW-2-port-group-all_access_vlan_1091]group-member gi0/0/3 to gi0/0/10
[L2-SW-2-port-group-all_access_vlan_1091]dis th
#
port-group all_access_vlan_1091
group-member GigabitEthernet0/0/3
group-member GigabitEthernet0/0/4
group-member GigabitEthernet0/0/5
group-member GigabitEthernet0/0/6
group-member GigabitEthernet0/0/7
group-member GigabitEthernet0/0/8
group-member GigabitEthernet0/0/9
group-member GigabitEthernet0/0/10
#
return
[L2-SW-2-port-group-all_access_vlan_1091]3、在端口组里面删除成员：
undo group-member命令将指定的以太网接口从端口组中删除。
[L2-SW-2-port-group-all_access_vlan_1091]undo group-member gi0/0/5
[L2-SW-2-port-group-all_access_vlan_1091]dis th
#
port-group all_access_vlan_1091
group-member GigabitEthernet0/0/3
group-member GigabitEthernet0/0/4
group-member GigabitEthernet0/0/6
group-member GigabitEthernet0/0/7
group-member GigabitEthernet0/0/8
group-member GigabitEthernet0/0/9
group-member GigabitEthernet0/0/10
#4、给端口组配置命令。
例如：将all_access_vlan_1091组口组中的接口模式设置为access模式。进入端口组后命令：port link-type access
port default vlan 1091
[L2-SW-2-port-group-all_access_vlan_1091]port link-type access
[L2-SW-2-GigabitEthernet0/0/3]port link-type access
[L2-SW-2-GigabitEthernet0/0/4]port link-type access
[L2-SW-2-GigabitEthernet0/0/6]port link-type access
[L2-SW-2-GigabitEthernet0/0/7]port link-type access
[L2-SW-2-GigabitEthernet0/0/8]port link-type access
[L2-SW-2-GigabitEthernet0/0/9]port link-type access
[L2-SW-2-GigabitEthernet0/0/10]port link-type access
[L2-SW-2-port-group-all_access_vlan_1091]port default vlan 1091
[L2-SW-2-GigabitEthernet0/0/3]port default vlan 1091
[L2-SW-2-GigabitEthernet0/0/4]port default vlan 1091
[L2-SW-2-GigabitEthernet0/0/6]port default vlan 1091
[L2-SW-2-GigabitEthernet0/0/7]port default vlan 1091
[L2-SW-2-GigabitEthernet0/0/8]port default vlan 1091
[L2-SW-2-GigabitEthernet0/0/9]port default vlan 1091
[L2-SW-2-GigabitEthernet0/0/10]port default vlan 1091
[L2-SW-2-port-group-all_access_vlan_1091]5、删除端口组中某个端口的模式或所属vlan，直接将此端口从端口组中删除，然后重新给端口配置或者加入其它端口组；
