Note
For explanations of VLAN name and VLAN identifier, refer back to
“VLAN Name” on page 562 and “VLAN Identifier” on page 562.
Tagged and
Untagged Ports
You need to specify which ports will be members of the VLAN. In the case
of a tagged VLAN, it is usually a combination of both untagged ports and
tagged ports. You specify which ports are tagged and which untagged
when you create the VLAN.
An untagged port, whether a member of a port-based VLAN or a tagged
VLAN, can be in only one VLAN at a time. However, a tagged port can be
a member of more than one VLAN. A port can also be an untagged
member of one VLAN and a tagged member of different VLANs
simultaneously.
Port VLAN
Identifier
As explained earlier in the discussion on port-based VLANs, the PVID of a
port determines the VLAN where the port is an untagged member.
Because a tagged port determines VLAN membership by examining the
tagged header within the frames that it receives and not the PVID, you
might conclude that there is no need for a PVID. However, the PVID is
used if a tagged port receives an untagged frame—a frame without any
tagged information. The port forwards the frame based on the port’s PVID.
This is only in cases where an untagged frame arrives on a tagged port.
Otherwise, the PVID on a tagged port is ignored.
Guidelines to
Creating a
Tagged VLAN
Below are the guidelines to creating a tagged VLAN.
Each tagged VLAN must have a unique VID. If a VLAN spans multiple
switches, each part of the VLAN on the different switches must have
the same VID.
A tagged port can be a member of multiple VLANs.
An untagged port can be an untagged member of only one VLAN at a
time.
The switch can support up to a total of 4094 port-based, tagged,
protected ports, and MAC address-based VLANs.
