CISCO PT Simulation Experiment (4) VLAN partitioning and configuration of switches

Experimental Purpose :

Master The basic configuration of virtual LANs (VLANs);

Master the configuration method of switch port VLAN and tag VLAN;

Master the configuration method for VLAN trunking (VLAN trunk) and its Protocol (VTP).

Experimental background : The company's finance department, sales department of the PC are placed in two offices , and through the indoor switch interconnection to achieve communication; for data security purposes, communication isolation between the two departments is required, The switch is now configured appropriately to achieve this goal.

Technical Principle :

• VLAN technology: Refers to a physically connected network segment logically divided into a number of virtual local area networks. VLAN features are not constrained by physical locations and can be flexibly partitioned. Each VLAN has the characteristics of a physical network segment, which corresponds to a broadcast domain . Hosts within the same VLAN can communicate with each other directly, and each other between hosts in different VLANs must be forwarded by a routed device.

• port VLAN is one of the ways to implement VLANs, it is based on the port of the Switch VLAN partition, a port can only belong to one VLAN.

• < Span style= "FONT-SIZE:10.5PT;LINE-HEIGHT:19.5PT;" >

  • tag A VLAN is a type of switch-based port (that is, an access port) that is used primarily for direct access between hosts within the same VLAN across switches, while isolating hosts in different VLANs.

• vlan trunk (Vlan trunk), refers to the switch with the switch or router, in the case of the interconnection port configuration relay mode, so that the data frame belonging to different VLANs can be transmitted through this trunk link.

• (default) , client mode, transparent mode.

• • vlan Sub-mode             Switch (VLAN) #

  • vlan configuration mode                 Switch (Config-vlan) #

  • vlan interface (SVI) mode         Switch (config-if) #

Experimental Equipment : switch_2960 2 units, PC 4, straight line, crossover line.

Experimental steps:

VLAN 2 and VLAN 3 are created, the Finance department corresponds to VLAN 2, and the sales department corresponds to VLAN 3

Partition the departmental PC corresponding port into the appropriate VLAN

Configure VTP mode and VTP domain name for the switch

Configure ports for inter-switch interconnect to trunk type
