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.
Configure the hashing key used to hash link aggregation group (LAG) and equal-cost
multipath (ECMP) traffic.
The hashing algorithm is used to make traffic-forwarding decisions for traffic entering a
LAG bundle or for traffic exiting a switch when ECMP is enabled.
For LAG bundles, the hashing algorithm determines how traffic entering a LAG bundle is
placed onto the bundle's member links. The hashing algorithm tries to manage bandwidth
by evenly load-balancing all incoming traffic across the member links in the bundle.
When ECMP is enabled, the hashing algorithm determines how incoming traffic is
forwarded to the next-hop device.
The remaining statements are explained separately.
