Modifying a Protected Ports VLAN
Please note the following before you perform this procedure:
ˆ 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 680.
ˆ 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.
ˆ An untagged port removed from a VLAN is automatically returned to
the Default_VLAN.
ˆ 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 680.
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 206 on page 610.
2. From the VLAN Configuration menu, type 4 to select Configure
VLANs.
The Configure VLANs menu is shown in Figure 207 on page 611.
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 666.
3. From the Configure VLANs menu, type 2 to select Modify VLAN.
