VLAN Commands
4-309
4
• If ingress filtering is disabled and a port receives frames tagged for VLANs for
which it is not a member, these frames will be flooded to all other ports (except
for those VLANs explicitly forbidden on this port).
• If ingress filtering is enabled and a port receives frames tagged for VLANs for
which it is not a member, these frames will be discarded.
• Ingress filtering does not affect VLAN independent BPDU frames, such as
GVRP or STA. However, they do affect VLAN dependent BPDU frames, such
as GMRP.
Example
The following example shows how to select port 1 and then enable ingress filtering:
switchport native vlan
This command configures the PVID (i.e., default VLAN ID) for a port. Use the
no
form to restore the default.
Syntax
switchport native vlan
vlan-id
no switchport native vlan
vlan-id
- Default VLAN ID for a port. (Range: 1-4094, no leading zeroes)
Default Setting
VLAN 1
Command Mode
Interface Configuration (Ethernet, Port Channel)
Command Usage
• If an interface is not a member of VLAN 1 and you assign its PVID to this
VLAN, the interface will automatically be added to VLAN 1 as an untagged
member. For all other VLANs, an interface must first be configured as an
untagged member before you can assign its PVID to that group.
• If acceptable frame types is set to
all
or switchport mode is set to
hybrid
, the
PVID will be inserted into all untagged frames entering the ingress port.
Example
The following example shows how to set the PVID for port 1 to VLAN 3:
Console(config)#interface ethernet 1/1
Console(config-if)#switchport ingress-filtering
Console(config-if)#
Console(config)#interface ethernet 1/1
Console(config-if)#switchport native vlan 3
Console(config-if)#
