3.12.11 Example for Configuring the MUX VLAN
MUX VLAN isolates Layer 2 traffic of different interfaces in a VLAN. It allows some employee
users of an enterprise to communicate with each other and isolates some employee users from
each other.
Networking Requirements
In an enterprise network, all employees of the enterprise can access the enterprise's server. It is
required that some employees be able to communicate with each other, whereas some employees
not communicate with each other.
As shown in Figure 3-20,in an enterprise network, all employees of the enterprise can access
the enterprise's server. It is required that some employees be able to communicate with each
other, whereas some employees not communicate with each other.
For an enterprise with a large number of employees, each employee that is prohibited from
communicating with another needs to be added to a separate VLAN if the preceding scheme is
used. This wastes VLAN ID resources and imposes an additional configuration workload on the
network administrator.
Configuring a MUX VLAN on the switch connected to PCs helps to save VLAN ID resources,
reduce the configuration workload of the network administrator, and facilitate network
maintenance.
