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 VLAN mode.
The difference between the two procedures has to do with ingress
filtering. If you activate the Basic VLAN 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 window in Figure 68 on page 211 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 VLAN Mode.
