5850+5120组网

您好，请知：

关于一个网段给多个VLAN使用，可以使用supervlan来实现，以下是配置举例，请参考：

2.5  Super VLAN典型配置举例

1. 组网需求

Device A连接不同VLAN用户，其中，端口GigabitEthernet1/0/1和端口GigabitEthernet1/0/2属于VLAN 2，端口GigabitEthernet1/0/3和端口GigabitEthernet1/0/4属于VLAN 3，端口GigabitEthernet1/0/5和端口GigabitEthernet1/0/6属于VLAN 5。

为实现Device A连接的各VLAN用户（均在10.1.1.0/24网段）之间能够满足二层隔离和三层互通的同时，节省IP资源，创建Super VLAN，其关联的Sub VLAN公用Super VLAN interface的IP地址10.1.1.1/24作为三层通信的网关地址。

3. 配置步骤

# 创建VLAN 10，配置VLAN接口的IP地址为10.1.1.1/24。

<DeviceA> system-view

[DeviceA] vlan 10

[DeviceA-vlan10] quit

[DeviceA] interface vlan-interface 10

[DeviceA-Vlan-interface10] ip address 10.1.1.1 255.255.255.0

# 开启设备的本地代理ARP功能。

[DeviceA-Vlan-interface10] local-proxy-arp enable

[DeviceA-Vlan-interface10] quit

# 创建VLAN 2，并向VLAN 2中添加端口GigabitEthernet1/0/1和端口GigabitEthernet1/0/2。

[DeviceA] vlan 2

[DeviceA-vlan2] port gigabitethernet 1/0/1 gigabitethernet 1/0/2

[DeviceA-vlan2] quit

# 创建VLAN 3，并向VLAN 3中添加端口GigabitEthernet1/0/3和端口GigabitEthernet1/0/4。

[DeviceA] vlan 3

[DeviceA-vlan3] port gigabitethernet 1/0/3 gigabitethernet 1/0/4

[DeviceA-vlan3] quit

# 创建VLAN 5，并向VLAN 5中添加端口GigabitEthernet1/0/5和端口GigabitEthernet1/0/6。

[DeviceA] vlan 5

[DeviceA-vlan5] port gigabitethernet 1/0/5 gigabitethernet 1/0/6

[DeviceA-vlan5] quit

# 配置VLAN 10为Super VLAN，其关联的Sub VLAN为VLAN 2、VLAN 3和VLAN 5。

[DeviceA] vlan 10

[DeviceA-vlan10] supervlan

[DeviceA-vlan10] subvlan 2 3 5

[DeviceA-vlan10] quit

[DeviceA] quit

4. 显示和验证

# 查看Super VLAN的相关信息，验证以上配置是否生效。

<DeviceA> display supervlan
