Modifying a Protected Ports VLAN
Please note the following before you perform this procedure:
❑ To modify this type of VLAN, you must recreate it by reselecting
the uplink port(s) and reassigning the ports to the groups. For this
reason Allied Telesyn recommends that before you perform this
procedure you first display the details of the protected ports VLAN
you want to modify and write down on paper the VLAN’s current
configuration (i.e., uplink port and port to group assignments).
This provides information that allows you to recreate the current
configuration, with whatever modifications you want to make,
when you perform the procedure. To display a VLAN’s
configuration, refer to ”Displaying a Protected Ports VLAN” on
page 510.
❑ If you are adding untagged ports, the ports must be untagged
members of the Default_VLAN or a port-based or tagged VLAN.
They cannot be members of another protected ports VLAN.
❑ An untagged port removed from a VLAN is automatically returned
to the Default_VLAN.
❑ A port that is already an untagged member of a protected ports
VLAN cannot be made an untagged member of another VLAN
until it is first removed from its current VLAN assignment and
returned to the Default_VLAN.
Note
To modify a VLAN, you need to know its VID. To view VLAN VIDs,
refer to ”Displaying a Protected Ports VLAN” on page 510.
To modify a protected ports VLAN, perform the following procedure:
1. From the Main Menu, type 2 to select VLAN Configuration.
The VLAN Configuration menu is shown in Figure 135 on page
441.
2. From the VLAN Configuration menu, type 4 to select Configure
VLANs.
The Configure VLANs menu is shown in Figure 136 on page 442.
Note
If selection 4, Configure VLANs, is not displayed in the menu, the
switch is running a multiple VLAN mode. To change a switch’s VLAN
mode, refer to ”Selecting a VLAN Mode” on page 468.
