6. The default acceptframe type for all ports is "Untagged".
An interface can have only one native VLAN. It can be untagged or tagged. Untagged VLANs on an
interface are native VLANs by default. On an interface where there is an untagged VLAN, there can be
tagged VLANs, but not tagged native VLANs. Another way to say this is that an interface with a tagged
native VLAN cannot be a member of another VLAN as untagged. When you configure a tagged native
VLAN on an interface, the interface should be removed from the default VLAN (VLAN 1 untagged
native).
Note: If an interface is already a member of an untagged VLAN other than 1, you must remove
it before you can add a tagged native VLAN to it, since there cannot be more than one native
VLAN on an interface. For example, if a particular port is a member of VLAN 3 untagged, you
must remove it from VLAN 3 untagged before you can add it to VLAN 4 as tagged native.
Two commands can configure a native VLAN:
• tagged

Whichever is configured first will be allowed for the interface, and subsequent requests for the native
VLAN will be rejected (First use the
If the interface is untagged for one VLAN, it cannot be untagged for any other VLAN, and this is the
native VLAN for the interface (only one native VLAN per port).
By default, VLAN 1 is the native VLAN. Until another VLAN is configured to be the native VLAN,
VLAN 1 will be the native VLAN and cannot be removed.
Two commands can unconfigure the native VLAN configuration:
• no tagged native (
