Usage Information
You can congure the optimal switchover functionality for LACP even if you do not enable the fast boot mode on
the system. You must congure the long timeout mechanism for the LACP session to enable the fast boot
capability to operate properly. This command applies to dynamic port-channel interfaces only. When applied on a
static port-channel, this command has no eect
If you congure the optimized booting-time capability and perform a reload of the system, the LACP application
sends PDUs across all the active LACP links immediately.

encapsulation dot1q
Congures lite-subinterfaces.
Syntax
encapsulation dot1q vlan-id
To remove a previously congured 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

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-
