Chapter 28: Port-based, Tagged, and Multiple Mode VLAN Commands
494 Section VI: Virtual LANs
type Specifies the type of VLAN to be created. The
option PORT signifies a port-based or tagged
VLAN. This parameter is optional.
ports Specifies the ports on the switch that are either
tagged or untagged members of the new VLAN.
You can specify the ports individually (for example,
5, 7, 22), as a range (for example, 18-23), or both
(for example, 1, 5, 14-22). To specify all ports on the
switch, use ALL. This parameter must be followed
by the FRAME parameter.
frame Specifies whether the ports of the VLAN are to be
tagged or untagged. This parameter must be used
with the PORT parameter.
taggedports Specifies the ports on the switch to serve as tagged
ports in the VLAN. To specify all ports on the switch,
use ALL. Omit this parameter if the VLAN does not
contain tagged ports.
untaggedports Specifies the ports on the switch to function as
untagged ports in the VLAN. To specify all ports on
the switch, use ALL. Omit this parameter if the
VLAN does not contain untagged ports.
Description
This command creates a port-based or tagged VLAN.
This command has two syntaxes. You can use either syntax to create a
port-based or tagged VLAN. The difference between the two syntaxes is
how you specify which ports are members of the VLAN and whether the
ports are tagged or untagged. Syntax 1 is limited because it allows you to
specify either tagged or untagged ports, but not both at the same time. On
the other hand, you can use Syntax 2 to create a VLAN that has both
types of ports. This is illustrated in the Examples section below.
When you create a new VLAN, untagged ports of the new VLAN are
automatically removed from their current untagged VLAN assignment.
This is because a port can be an untagged member of only one VLAN at a
time. For example, creating a new VLAN with untagged Ports 1 to 4
automatically removes these ports from whichever VLAN they are
currently untagged members.
The PVID of an untagged port is automatically changed to match the VID
number of the VLAN where it is added. For instance, if you add port 4 as
an untagged member of a VLAN with a VID of 15, the PVID for port 4 is
automatically changed to 15.
