Configuring VLAN Interfaces (Cont.)
Command Function
switchport ingress-filtering
This command enables ingress filter-
ing for an interface.
Use the no form to restore the default.
Syntax:
[no] switchport ingress-filtering
Default Setting: Disabled
Command Mode: Interface Configuration (Ethernet, Port Channel)
Command Usage: Ingress filtering only affects tagged frames.
• 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 set the interface to
port 1 and then enable ingress filtering:
Console(config)#interface ethernet 1/1
Console(config-if)#switchport ingress-filtering
Console(config-if)#
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 native vlan 3
Console(config-if)#
