To remove a previously configured lite-subinterface, use the no encapsulation dot1q vlan-id
command.
Parameters
dot1q vlan-id Enter the keyword dot1q followed by the VLAN ID to which the host belongs. The
range is from 1 to 4094. A lite subinterface is considered as a Layer 3 port property
and is synchronous with the existing rules of applying Layer 2 or Layer 3 properties
to an interface.

Usage
Information
To enable routing of RRoCE packets, the VLAN ID is mapped to the default VLAN ID of 4095 and this
mapping is performed using VLAN translation. After VLAN translation, the RRoCE packets are considered
in the same manner as normal IP packets that received on L3 interface and routed in the egress direction.
At the egress interface, the VLAN ID is appended to the packet and transmitted out of the interface as a
tagged packet with the dot1Q value preserved. The dot1Q value is preserved only for egress interfaces
that are associated with a VLAN or a lite-subinterface . If a Layer 3 interface is configured without the
encapsulation 802.1Q VLAN ID or is an untagged interface in a VLAN , the dot1Q value is not preserved .
