encapsulation
Use this command to configure encapsulation-type for a Layer 2 subinterface. With this command, a Layer 2 subinterface can be configured as single-tagged with single/multiple VLANs or double-tagged, or default or untagged. Operational state of the Layer 2 subinterface is DOWN before configuring the encapsulation and it becomes UP once the encapsulation is configured.
Use the no form of this command to remove the encapsulation.
Note: For encapsulation with a VLAN range in an inner tag or outer tag, overlapping VLANs either as a single value or a range will not be allowed under same parent port.
Command Syntax
encapsulation ((dot1q | dot1ad | default | untagged) (vlan-id | vlanid-range) (inner-dot1q (vlan-id | vlanid-range)))
no encapsulation ((dot1q | dot1ad | default | untagged) (vlan-id | vlanid-range) (inner-dot1q (vlan-id | vlanid-range)))
Parameters

Default
None
