Section VI: Virtual LANs 491
This command has two syntaxes. You can use either command to add
ports to a VLAN. The difference between the two is that Syntax 1 can add
only one type of port, tagged or untagged, at a time to a VLAN, while
Syntax 2 can add both in the same command. This is illustrated in
Examples below.
When you add untagged ports to a VLAN, the ports 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, if you add port 4 as an untagged port to a VLAN, the port is
automatically removed from whichever VLAN it is currently an untagged
member.
Adding a tagged port to a VLAN does not change the port’s current tagged
and untagged VLAN assignments. This is because a tagged port can
belong to more than one VLAN at a time. For instance, if you add port 6 as
an tagged port to a new VLAN, port 6 remains a tagged and untagged
member of its other VLAN assignments.
If the switch is using 802.1x port-based network access control, a port set
to the authenticator or supplicant role must be changed to the 802.1x none
role before its untagged VLAN assignment can be changed. After the
VLAN assignment is made, the port’s role can be changed back again to
authenticator or supplicant, if necessary.
Examples
The following command uses Syntax 1 to add ports 4 and 7 as untagged
members to a VLAN called Sales:
add vlan=sales ports=4,7 frame=untagged
The following command does the same thing using Syntax 2:
add vlan=sales untaggedports=4,7
The following command uses Syntax 1 to add port 3 as a tagged member
to a VLAN called Production:
add vlan=production ports=3 frame=tagged
The following command does the same thing using Syntax 2:
add vlan=production untaggedports=3
Adding both tagged and untagged ports to a VLAN using Syntax 1 takes
two commands, one command for each port type. For example, if you had
a VLAN called Service and you wanted to add port 5 as a tagged port and
ports 7 and 8 as untagged ports, the commands would be:
add vlan=Service ports=5 frame=tagged
