Chapter 29: Port-based, Tagged, and Multiple Mode VLAN Commands
522 Section VI: Virtual LANs
Note
You cannot change a VLAN’s name or VID.
When you remove an untagged port from a VLAN, the following happens:
 The port is returned to the Default_VLAN as an untagged port.
 If the port is also a tagged member of other VLANS, those VLAN
assignments are not changed. The port remains a tagged member of
the other VLANs. For example, if you remove Port 4 from a VLAN, the
port is automatically returned as an untagged port to the Default
VLAN. If Port 4 is functioning as a tagged member in one or more
other VLANs, it remains as a tagged member of those VLANs.
 If you remove an untagged port from the Default_VLAN without
assigning it to another VLAN, the port is excluded as an untagged
member from all VLANs on the switch.
When you remove a tagged port from a VLAN, all of its other tagged and
untagged VLAN assignments remain unchanged.
Examples
The following command uses Syntax 1 to delete untagged ports 4 and 7
from a VLAN called Sales:
delete vlan=sales ports=4,7 frame=untagged
The following command does the same thing using Syntax 2:
delete vlan=sales untaggedports=4,7
The following command uses Syntax 1 to delete tagged port 13 from a
VLAN called Production:
delete vlan=production ports=13 frame=tagged
The following command does the same thing using Syntax 2:
delete vlan=production untaggedports=13
To delete both tagged and untagged ports from a VLAN using Syntax 1
takes two commands. For example, if you had a VLAN called Service and
you wanted to delete from the VLAN tagged port 2 and untagged ports 6 to
8, the commands would be:
delete vlan=Service ports=2 frame=tagged
delete vlan=Service ports=6-8 frame=untagged
Using Syntax 2, you can do the whole thing with just one command:
delete vlan=Service untaggedports=6-8 taggedports=2
