Enabling or Disabling VLANs
This procedure performs exactly the same function as the previous
procedure. It sets a switch’s VLAN mode. When VLANs are enabled, the
switch supports port-based and tagged VLANs. When VLANs are
disabled, the switch supports the Basic mode.
The difference between the two procedures has to do with ingress
filtering. If you activate the Basic Mode using the previous procedure,
ingress filtering is disabled. Performing this procedure does not change
the current setting of ingress filtering.
To configure a switch’s VLAN mode, perform the following procedure:
1. From the Home page, select Configuration.
2. From the Configuration menu, select Layer 2.
3. From the Layer 2 window, select the VLAN tab.
The VLAN menu in Figure 89 on page 279 is displayed.
4. Click the Enable VLAN check box. A check in the box indicates that
the switch supports tagged and untagged VLANs. No check in the box
indicates that the switch is operating in the Basic Mode.
5. Click Apply.
6. Reset the switch. For instructions, refer to Resetting a Switch on
page 241. A change to VLAN status is not activated until the switch is
reset.
