S5500，有VLAN映射功能吗，如何配置

您好，参考

1.4  VLAN映射典型配置举例

1.4.1  1:1和N:1 VLAN映射配置举例

1. 组网需求

l              为了节省VLAN资源，用户希望从园区交换机Switch C发出的相同业务报文可共用一个VLAN，即：PC业务通过VLAN 501发送；VoD业务通过VLAN 502发送；VoIP业务通过VLAN 503发送。

l              不同家庭的相同业务报文之间要进行隔离，以免产生混淆。

2. 组网图

3. 配置步骤

(1)        配置Switch A

# 创建CVLAN和SVLAN。

<SwitchA> system-view

[SwitchA] vlan 2 to 3

[SwitchA] vlan 101 to 102

[SwitchA] vlan 201 to 202

[SwitchA] vlan 301 to 302

# 配置上行策略p1和p2：将不同用户的不同业务CVLAN映射到不同的SVLAN上。
