Hash diversification for LAGs and IP load balancing

In a multi-stage network a traffic flow will normally use the same LAG port or same path (for IP load

balancing) at each stage. The Hash Diversification feature works within an earlier stage of the hash

calculation than the hash rotate feature. Using the load-balance hash-diversify command, you can

provide a unique hash diversify value to a device, or a sub-set of ports on a device. This unique

value is used in calculation of the ECMP and LAG index hash. Consequently, instead of a traffic flow

always following the same port group or path, it will be distributed over different LAG or ECMP

members. To apply hash diversification, use the following command.

Brocade(config)# load-balance hash-diversify random all

Syntax: [no] load-balance hash-diversify [ number | random | slot ] [all | slot-number |

slot-number np-id ]

You can set the unique hash diversify value using one of the following options:

The number option allows you to specify a value from 0 - 255.

The random option directs the CPU to generate a random number for each packet processor and

program it as the hash diversification value.

The slot option specifies the slot ID as the has diversification number.

The default value for the diversification number is 0 and the no version of the command resets the

value to 0 regardless of any value previously set. Also, the most recent command added overrides

any previous instances of the command. For example, if the random option is entered first and is

then followed by the slot option, the value of the slot ID for the specified slot will be used.

The all option applies the command to all ports within the device.

Field Description

Slot Shows the slot of the interface on which the MPLS masking is enabled.

Mask MPLS Label Shows whether or not the following labels are masked.

• Label0 - Shows if the Label 0 is masked on the interface.

• Label1 - Shows if the Label 1 is masked on the interface.

• Label2 - Shows if the Label 2 is masked on the interface.
