Description

Select the payload fields in an IPv6 packet used by the hashing algorithm to make hashing decisions.

When IPv6 traffic enters a LAG and the hash mode is set to Layer 2 payload, the hashing algorithm checks the fields configured using this statement and uses the information in the fields to decide how to place traffic onto the LAG bundle’s member links or to forward traffic to the next hop device when ECMP is enabled.

The hashing algorithm, when used to hash LAG traffic, always tries to manage bandwidth by evenly load-balancing all incoming traffic across the member links in the bundle.

The hashing algorithm only inspects the IPv6 fields in the payload to make hashing decisions when the hash mode is set to Layer 2 payload. The hash mode is set to Layer 2 payload by default. You can set the hash mode to Layer 2 payload using the set forwarding-options enhanced-hash-key hash-mode layer2-payload statement.

Default

The data in the following fields are used by the hashing algorithm to make hashing decisions for IPv6 traffic:

• IP destination address

• IP source address

• Layer 4 destination port

• Layer 4 source port

• Next header
