port 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 to which it is added. For instance, if you make port 4
an untagged member of a VLAN with a VID of 15, port 4’s PVID is
changed to 15 automatically.
Tagged ports of the new VLAN remain as tagged and untagged members
of their current VLAN assignments. No change is made to a tagged port’s
current VLAN assignments, other than its addition to the new VLAN. This
is because a tagged port can belong to more than one VLAN at a time. For
example, if you add port 6 as a tagged port to a new VLAN, port 6 remains
