Chapter 25: Protected Ports VLANs
282 Section VI: Virtual LANs
To create a protected ports VLAN, you perform many of the same steps
that you do when you create a new port-based or tagged VLAN. You give
it a name and a unique VID, and you indicate which of the ports will be
tagged and untagged. What makes creating this type of VLAN different is
that you must assign the ports of the VLAN to their respective groups.
Following is an example of a protected ports VLAN. The first table lists the
name of the VLAN, the VID, and the tagged and untagged ports. It also
indicates which port will function as the uplink port, in this case port 22.
The second table lists the different groups in the VLAN and the ports for
each group.
Allied Telesis recommends that you create tables similar to these before
you create your own protected ports VLAN. Having the tables handy will
make your job easier when the switch prompts you for this information.
