Flex Hash and Optimized Boot-Up

This chapter describes the Flex Hash and fast-boot enhancements.

Topics:

• encapsulation dot1q

• lacp fast-switchover

• load-balance flexhash

• load-balance ingress-port enable

encapsulation dot1q

Configures lite-subinterfaces. This command is supported on the S6000 platform.

Syntax

encapsulation dot1q vlan-id

To remove a previously configured lite-subinterface, use the no version of this 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.

Command History

Version

9.9(0.0) Introduced on the C9010.

9.3.0.0 Introduced on the S6000 platform.

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 are received on Layer 3 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 .

lacp fast-switchover

Cause the physical ports to be aggregated faster by configuring this capability in a port-channel on both the nodes that are members of a

port-channel.

C9000 Series

Syntax

lacp fast-switchover

To disable the capability of faster aggregation of the member ports of a LAG or a port-channel bundle, use the no

version of this command.
