Release Information

Statement introduced in Junos OS Release 13.3.

Description

Configure hash policy. Though we do not have direct control over the data packet distribution over the slave interfaces, the standard offers us three different kinds of hashing schemes (listed below) to have good balance of traffic over these slave interfaces.

Default

The default hash-policy is layer-3-and-4.

Options

hash-policy hash-policy-option

—

Three different hashing schemes are offered:

layer-2—Uses the MAC address of both source and destination for hashing.
layer-2-and-3—Uses the MAC and IP addresses of both source and destination for hashing.
layer-3-and-4—Uses port number and IP address of both source and destination for hashing.
