Chapter 19: Port-based and Tagged VLANs
460 Section III: VLANs
Activating or deactivating ingress filtering has no effect on the switch’s
handling of priority tags. A switch will always examines a priority tag in a
tagged frame, without regard to the status of ingress filtering.
In most cases, you will probably want to leave ingress filtering activated
on the switch, which is the default. You can enable or disable ingress
filtering on a per switch basis. You cannot set this per port.
To enable or disable ingress filtering, 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 1 to select Ingress Filtering
Status.
The following prompt is displayed:
Enter Ingress Filtering Status (E-Enable, D-Disable) ->
3. Type E to activate ingress filtering or D to disable the feature on the
switch.
A change to the status of ingress filtering is immediately activated
on the switch.
4. After making changes, type R until you return to the Main Menu. Then
type S to select Save Configuration Changes.
