Chapter 16: VLAN and MVLAN Commands
188
port Specifies the ports (that is, slot.port) on the switch
that are either tagged or untagged members of the
new VLAN. 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 (that is, slot.port) 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 (that is, slot.port) 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
of a line card an untagged member of a VLAN with a VID of 15, Port 4’s
PVID is changed to 15 automatically.
