Example
The following example shows how to set the PVID for port 1 to VLAN 3:
switchport allowed vlan
Use this command to configure 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: 1-4094).
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.
• If a VLAN on the forbidden list for an interface is manually added to that
interface, the VLAN is automatically removed from the forbidden list for that
interface.
