Chapter 29: Port-based, Tagged, and Multiple Mode VLAN Commands
510 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:
ˆ The port is returned to the Default_VLAN as an untagged port.
ˆ 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.
ˆ 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.
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 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 tagged port 2 and untagged ports 6 to 8, the
commands would be:
