交换机trunk和access

交换机端口工作模式简介

端口类型	工作模式
Access类型	端口只能属于1个VLAN，一般用于连接计算机的端口
Trunk类型	端口可以允许多个VLAN通过，可以接收和发送多个VLAN的报文，一般用于交换机之间连接的端口
Hybrid类型	端口可以允许多个VLAN通过，可以接收和发送多个VLAN的报文，可以用于交换机之间连接，也可以用于连接用户的计算机

注：

• Hybrid端口和Trunk端口在接收数据时，处理方法是一样的，唯一不同之处在于发送数据时：Hybrid端口可以允许多个VLAN的报文发送时不打标签，而Trunk端口只允许缺省VLAN的报文发送时不打标签。也就是说，Trunk端口报文发送一般都要打标，而Hybrid可以允许多个VLAN不打标。
• 三种类型的端口可以共存在一台以太网交换机上，但Trunk端口和Hybrid端口之间不能直接切换，只能先设为Access端口，再设置为其他类型端口。例如：Trunk端口不能直接被设置为Hybrid端口，只能先设为Access端口，再设置为Hybrid端口。

各种模式接收和发送数据

华为交换机简单操作命令

1. 通过ssh进入
2. 进入系统system
3. 操作具体的端口
   配access模式、VLAN

设置限速：

1. 创建限速模板

qos car EMB-4-10000 cir 10240000 kbps

2. 给端口设置限速

#先清除端口的配置
interface 10GE1/0/2
undo port link-type
undo port default vlan
undo qos car inbound
undo qos lr outbound
undo shutdown
q
#配置端口模式、vlan、限速
interface 10GE1/0/2
port link-type trunk
port trunk allow-pass vlan 2086 3014
qos car inbound EMB-4-10000
qos lr cir 10240000 kbps cbs 524288 kbytes 
undo shutdown
q
commit

3. 创建vlan

[~HUAWEI]vlan 20
[*HUAWEI-vlan20]q
[*HUAWEI]commit

[~HUAWEI]vlan batch 10 to 12(创建vlan 10 11 12)

[~HUAWEI]display vlan
