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.
Examples
The following command uses Syntax 1 to add ports 4 and 7 as untagged
members to a VLAN called Sales:
add vlan=sales port=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 port=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 port=5 frame=tagged
add vlan=Service port=7-8 frame=untagged
Using Syntax 2, you can add both types of ports with just one command:
add vlan=Service untaggedports=7-8 taggedports=5
