interface vlan

VLAN ID number.

Range:1-4094

Name of the bandwidth contract to be applied to this VLAN interface. When applied to a VLAN, the contract limits both broadcast and multicast traffic. Use theaaa bandwidth-contractcommand to configure a bandwidth contract.

启用广播和多播流量优化，以防止VLAN上的广播和多播流量泛滥。如果在上行链路端口上启用了此功能，托管设备-generated Layer-2 packets will be dropped.

默认：禁用

String that describes this interface.

默认：802.1q VLAN

在配置助手时，过滤器DHCP发现广播。

配置助手时，过滤DHCPV6客户端多播数据包。

为此接口配置IPv4。

Assigns an access list to inbound traffic on the interface, where is the name of an access list.

路由ACL是可以在VLAN接口上配置的唯一支持的ACL类型。其他ACL类型不支持。

Configures the IP address for this interface, which can be one of the following:

• dhcp-client: use DHCP to obtain the IP address
• internal: IP address allocated from the branch group config.
• PPPOE：使用PPPOE获得IP地址

IP address of the DHCP server for relaying DHCP requests for this interface. If the DHCP server is on the same subnetwork as this VLAN interface, you do not need to configure this parameter.

在此接口上启用IGMP代理或IGMP侦听。看interface vlan ip igmp

for complete details on this parameter.

启用本地代理ARP。

启用源NAT，以适用于与此VLAN的所有流量。

警告：All ports on the托管设备默认情况下分配给VLAN 1。不要启用内部VLAN 1的选项，因为这将防止IPSEC连接托管设备及其IPSEC同行。

定义OSPF区域。看接口VLAN IP OSPFfor complete details on this parameter.

在字节中配置TCP MSS。

Range:128

Configures the PAP password on the PPPoE Access Concentrator for the switch.

Range:1-80

配置PPPOE服务名称。

Range:1-80

在开关的PPPOE访问浓度器上配置PAP用户名。

Range:1-80

使用子参数指定NAT IP地址而不是实际的PPPOE网关IP地址以配置默认路由。

在VLAN接口上启用第3层转发。要禁用第3层转发，您必须配置接口的IP地址并指定no ip routing。

默认：enabled

Configures IPv6 for this interface.

配置接口的IPv6地址。

• dhcp6-client- DHCPV6用于获得IPv6地址。
• link-local- The link local address
• pd- PD客户端在上行链路上获得的前缀。
• X:X:X:X::X/<0-128> - 用于配置此接口的全局单播地址的IPv6前缀/前缀长度。

Configures DHCP for IPv6.

• pdclient-DHCPV6前缀委托服务器的IPv6前缀。
• server- 为VLAN配置DHCPV6池。

IPv6 address of the DHCP server for relaying DHCP requests for this interface. If the DHCP server is on the same subnetwork as this VLAN interface, you do not need to configure this parameter.

Enables MLD on this interface.

代理人- Configures MLD proxy on the following interfaces.

• FastEthernet
• GigabitEthernet <插槽/模块/端口>
• 港口通道

snooping- 在此接口上配置MLD侦听。

Configures the IPv6 neighbor discovery options.

• RA- 配置以下路由器广告选项：
  • dns- Configures IPv6 recursive DNS server
  • dns-sl- Configures IPv6 recursive DNS server search list
  • enable- 启用IPv6 RA
  • hop-limit- 配置RA Hop-limit
  • interval- Configures RA interval
  • 寿命- 配置RA寿命
  • 托管config-flag- Enables hosts to use DHCP server for stateful address autoconfiguration
  • mtu- 为RA配置MTU
  • other-config-flag- 使主机能够使用DHCP服务器进行其他非地址状态的自动配置
  • 偏爱- 配置高/低/介质的路由器偏好
  • 字首- 配置IPv6 RA前缀
• 到达时间- 配置邻居发现到达时间。默认情况下，此字段设置为0。有效值-0-3，600,000毫秒。
• retransmit-time- 配置邻居发现重新发送时间。默认情况下，此字段设置为0。有效值-0-3，600,000毫秒。

Negates any configured parameter.

MTU setting for the VLAN.

Range:1024-1500

VLAN上的多模验证支持

Set the state of the interface to be up.

Allows a DHCP relay agent to insert circuit specific information into a request that is being forwarded to a DHCP server.

这托管设备, when acting as a DHCP relay agent, needs to be able to insert information about the AP and SSID through which a client is connecting into the DHCP request.

Many service providers use this mechanism to make access control decisions. You can include:

• AP名称或AP名称和essid。
• MAC address or MAC address and ESSID.

导致界面的严重关闭。
