Release Information Statement introduced in Junos OS Release 13.2X51-D15 for EX Series switches.
Statement introduced in Junos OS Release 13.2X51-D20 for QFX Series devices.
Description Select the payload fields in IPv4 traffic used by the hashing algorithm to make hashing
decisions.
When IPv4 traffic enters a LAG and the hash mode is set to Layer 2 payload, the hashing
algorithm checks the fields configured using the inet statement and uses the information
in the fields to decide how to place traffic onto the LAG bundle’s member links or how
to forward traffic to the next hop device when ECMP is enabled.
The hashing algorithm, when used to hash LAG bundle 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 IPv4 fields in the payload to make hashing
decisions when the hash mode is set to layer2-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 following fields are used by the hashing algorithm to make hashing decisions for
IPv4 traffic:
• IP destination address
• IP source address
• Layer 4 destination port
• Layer 4 source port
• Protocol
Options no-ipv4-destination-address—Exclude the IPv4 destination address field from the hashing
algorithm.
no-ipv4-source-address—Exclude the IPv4 source address field from the hashing algorithm.
no-l4-destination-port—Exclude the Layer 4 destination port field from the hashing
algorithm.
