Usage Information This command applies to any physical interface with speed set to 10/100.
NOTE: Starting with Dell EMC Networking OS version 7.8.1.0, when you use a copper SFP2
module with catalog number GP-SFP2-1T in the S25P model of the S-Series, you can manually set
its speed with the speed command. When you set the speed to 10 Mbps or 100 Mbps, you can also
execute the duplex command.

encapsulation dot1q
Configures lite-subinterfaces.
Syntax
encapsulation dot1q vlan-id
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 .
