Configuring VLAN Interfaces
20
Command Usage
When set to receive all frame types, any received frames that are untagged are assigned to the
default VLAN.
Example
The following example shows how to restrict the traffic received on port 1 to tagged frames:
Console(config)#interface ethernet 1/1
Console(config-if)#switchport acceptable-frame-types tagged
Console(config-if)#
Related Commands
switchport mode (384)
switchport allowed vlan
This command configures VLAN groups on the selected interface. Use the no form to restore the
default.
Syntax
switchport allowed vlan {add vlan-list [tagged | untagged] | remove vlan-list}
no switchport allowed vlan
add vlan-list - List of VLAN identifiers to add.
remove vlan-list - List of VLAN identifiers to remove.
vlan-list - Separate nonconsecutive VLAN identifiers with a comma and no spaces; use a
hyphen to designate a range of IDs. (Range: 1-4093).
Default Setting
All ports are assigned to VLAN 1 by default.
The default frame type is untagged.
Command Mode
Interface Configuration (Ethernet, Port Channel)
Command Usage
• A port, or a trunk with switchport mode set to hybrid, must be assigned to at least one VLAN as
untagged.
• If a trunk has switchport mode set to trunk (i.e., 1Q Trunk), then you can only assign an
interface to VLAN groups as a tagged member.
• Frames are always tagged within the switch. The tagged/untagged parameter used when
adding a VLAN to an interface tells the switch whether to keep or remove the tag from a frame
on egress.
• If none of the intermediate network devices nor the host at the other end of the connection
supports VLANs, the interface should be added to these VLANs as an untagged member.
Otherwise, it is only necessary to add at most one VLAN as untagged, and this should
correspond to the native VLAN for the interface.
