AT-S39 User’s Guide

When changing a VLAN’s name, observe the following guidelines:
❑ A VLAN’s new name cannot be the same as the name of another
VLAN on the same switch. For example, if the switch already
contains a VLAN called Sales, you cannot change an existing
VLAN’s name to Sales.
❑ You cannot change the name of the Default_VLAN.
Note
A VLAN must be assigned a name.
2 - VLAN ID (VID)
This is the VLAN’s VID value. You cannot change this value.
3 - Tagged Ports
Use this selection to add or remove tagged ports from the VLAN. You
can specify the ports individually (e.g., 2,3,5), as a range (e.g., 7-9), or
both (e.g., 2,5,7-9).
When adding or removing tagged ports, observe the following
guidelines:
❑ To add or remove tagged ports, enter the new list of tagged ports
for the VLAN. For example, if the VLAN currently contains tagged
port 4 and you wanted to add port 7, you would enter “4,7”.
❑ If the VLAN will not contain any tagged ports, leave this field
empty.
❑ If the VLAN contains tagged ports and you want to remove them
all, enter a 0 (zero) for this value.
4 - Untagged Ports
Use this selection to add or remove untagged ports from the VLAN.
You can specify the ports individually (e.g., 2,3,5), as a range (e.g., 7-9),
or both (e.g., 2,5,7-9).
When adding or removing untagged ports, observe the following
guidelines:
❑ To add or remove untagged ports, enter the new list of untagged
ports for the VLAN. For example, if the VLAN currently contains
untagged ports 15 through 19 and you want to add ports 4
through 9, you would enter “4-9,15-19”.
❑ If the VLAN does not contain untagged ports, leave this field
empty.
