VLAN and trunk port configuration

One 、VLAN The function of

      VLAN： Used to divide LAN 、 Broadcast area . The same network segment is divided into two or more small networks

Two 、VLAN The advantages of

     1. Control broadcast

      2. Enhanced security （ each VLAN You can't visit each other directly ）

      3. Managing the network is simpler

3、 ... and 、VLAN The type of

       1. Static VLAN ：

            Configure the interface statically VLAN

        2. Dynamic VLAN

            binding MAC Address to the interface VLAN

Four 、 static state VLAN Configuration of

       1. static state VLAN The scope of the

       2. Switch command （ Commands are written in user view ）

              display VLAN                  ## Show VLAN Information

              vlan batch 10 20 30        ### add to VLAN10 VLAN20 VLAN30   

               undo VLAN  10              ### Delete VLAN10

               int g0/0/0                        ### Get into 0/0/0 Interface

               port link-type access（Trunk）       #### Define the interface type as access still Trunk type

               port default vlan 10        #### To configure Get into VLAN10

               port-group group-member g0/0/3 to g0/0/5  #### to 3 Mouth and 5 Mouth into a group Then interface                     The definition of

              dis vlan 10                    ### see VLAN10 Configuration of

           5、 ... and 、 Switch VLAN Interface type

               1.access Interface type Access mode ： Generally used to connect Computer Or routing port

                effect ： When data enters the switch In the play vlan label , Outgoing switch Take off vlan label

               2. Turnk relay It is generally used to connect the switch and the port of the switch

                effect ： Used to identify the safe line of the class vlan label

               3.Hybrid Huawei's private agreement The default interface type on the Huawei switch interface

            6、 ... and 、Trunk Definition and configuration of

        1.Trunk： Will be different VLAN The data frame sent Label it and send it out to find the target address

       VLAN identification

      ISL（Ciscos Private standards ）

      IEEE802.1q

            7、 ... and 、VLAN Configuration of

  1. When the data arrives GE0/0/5 when , Need to use Trunk.

  2.int g0/0/5      ### Get into g0/0/5 Interface

  3.port link-type trunk  ## Define the type bits of the interface trunk
  4.port trunk allow-pass vlan 10 20 ### by trunk release 10 20（10,20 The parameter can be changed to all It means to release all VLAN mouth ）

   ps： The port in the simulator is open by default   

          Huawei switches need to be turned on manually     Open command      undo shutdown 

summary  

        To configure trunk More complicated , You need to be careful
