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. Do not
enter leading zeros. (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.
