    [SWB-vlan10]vlan 20
    [SWB-vlan20]port GigabitEthernet 1/0/3
    查看VLAN信息
    [SWA]display vlan
    Total VLANs: 3
    The VLANs include:
    1(default), 10, 20

    [SWA]display vlan
    Total VLANs: 3
    The VLANs include:

    [SWA]display vlan 10
    VLAN ID: 10
    VLAN type: Static

    Description: VLAN 0010
    Name: VLAN 0010
    Tagged ports: None
    Untagged ports:

    [SWA]display vlan 20
    VLAN ID: 20
    VLAN type: Static
    Route interface: Not configured
    Description: VLAN 0020
    Name: VLAN 0020
    Tagged ports: None
    Untagged ports:

    1. 测试VLAN间的隔离

      [PCD-GigabitEthernet0/0]ip ad 192.168.1.4 24
      显然不能够PCA和PCB在这种情况下不能互通。

    配置Hybrid链路端口
    [SWB-GigabitEthernet1/0/3]port trunk pvid vlan 30

    [SWA]vlan 10
    [SWA]vlan 20
    [SWA]vlan 30

    [SWA-GigabitEthernet1/0/3]port hybrid vlan 10 20 30 untagged
    [SWA-GigabitEthernet1/0/3]port hybrid pvid vlan 30
    //vlan 10 20必须是缺省的VLAN

    [SWA-GigabitEthernet1/0/1]port link-type hybrid
    [SWA-GigabitEthernet1/0/1]port hybrid vlan 10 30 untagged
    [SWA-GigabitEthernet1/0/1]port hybrid pvid vlan 10//基于端口VLAN
    [SWA-GigabitEthernet1/0/1]int ge 1/0/2
    [SWA-GigabitEthernet1/0/2]port hybrid pvid vlan 20
    [SWA-GigabitEthernet1/0/2]port link-type hybrid
    [SWA-GigabitEthernet1/0/2]port hybrid vlan 20 30 untagged

    实验发现PCA可以ping通PCC,PCD，但是ping不通PCB。
    实验过程发现下面问题：
    %May 26 17:24:00:579 2018 SWB LLDP/5/LLDP_PVID_INCONSISTENT: PVID mismatch discovered on GigabitEthernet1/0/1 (PVID 30), with SWA GigabitEthernet1/0/3 (PVID 1).
    一般组网情况下，要求链路两端的PVID保持一致。设备会对收到的LLDP报文中的PVID TLV进行检查，如果发现报文中的PVID与本端PVID不一致，则认为网络中可能存在错误配置，LLDP会打印日志信息，提示用户。

    实验任务二：基于协议的VLAN配置
    1． 建立物理连接
    2． 配置SWA和SWB
    [SWA-GigabitEthernet1/0/1]port link-type hybrid
    [SWA-GigabitEthernet1/0/1]port hybrid protocol-vlan vlan 10 0
    [SWA-GigabitEthernet1/0/1]port hybrid protocol-vlan vlan 20 0
    [SWA-GigabitEthernet1/0/1]port hybrid vlan 10 20 untagged

    [SWA-GigabitEthernet1/0/2]port link-type hybrid
    [SWA-GigabitEthernet1/0/2]port hybrid protocol-vlan vlan 10 0
    [SWA-GigabitEthernet1/0/2]port hybrid protocol-vlan vlan 20 0
    [SWA-GigabitEthernet1/0/2]port hybrid vlan 10 20 untagged

    [SWA-vlan10]protocol-vlan ipv4
    [SWA-vlan10]vlan 20
    [SWA-vlan20]protocol-vlan ipv6

    [SWA-GigabitEthernet1/0/3]port link-type trunk
    [SWA-GigabitEthernet1/0/3]port trunk permit vlan all

    SWB配置同上。

    3.查看SWA协议VLAN
    [SWA]display protocol-vlan vlan all
    VLAN ID: 10
    Protocol index Protocol type
    0 IPv4

    VLAN ID: 20
    Protocol index Protocol type
    0 IPv6

    PCA和PCB配置了IPV6地址互ping，但是结果如下。
    [SWA]display mac-address
    MAC Address VLAN ID State Port/Nickname Aging
    9a22-bdb8-0105 1 Learned GE1/0/1 Y
    9a22-e07c-0605 1 Learned GE1/0/3 Y

    在模拟器做实验失败了。

    实际看到应该是对应的vlan20 对应MAC地址。

    实验任务三：基于子网的VLAN配置

    1. 建立物理连接

    2. 配置SWA和SWB
      [SWA-vlan10]ip-subnet-vlan ip 10.0.0.0 255.255.255.0
      [SWA-vlan20]ip-subnet-vlan ip 20.0.0.0 255.255.255.0

    [SWA]int ge 1/0/1
    [SWA-GigabitEthernet1/0/1]port link-type hybrid
    [SWA-GigabitEthernet1/0/1]port hybrid ip-subnet-vlan vlan 10
    [SWA-GigabitEthernet1/0/1]port hybrid vlan 10 20 untagged
    [SWA-GigabitEthernet1/0/1]port hybrid ip-subnet-vlan vlan 20

    [SWA-GigabitEthernet1/0/2]port link-type hybrid
    [SWA-GigabitEthernet1/0/2]port hybrid ip-subnet-vlan vlan 20
    [SWA-GigabitEthernet1/0/2]port hybrid ip-subnet-vlan vlan 10
    [SWA-GigabitEthernet1/0/2]port hybrid vlan 10 20 untagged
    [SWA]int ge 1/0/3
    [SWA-GigabitEthernet1/0/3]port link-type trunk
    [SWA-GigabitEthernet1/0/3]port trunk permit vlan all

    SWB同上

    在模拟器做实验失败了。

    实际看到应该是对应的vlan20 对应MAC地址。

    有条命令可以设置VLAN匹配优先级。
    [H3C-GigabitEthernet1/0/1]vlan precedence ?
    ip-subnet-vlan Preferentially match IP-subnet VLAN
    mac-vlan Preferentially match MAC VLAN
    子网还是Mac地址优先。
