Syntax show forwarding-options enhanced-hash-key
Release Information Command introduced in Junos OS Release 13.2X51-D15 for EX Series switches.
Command introduced in Junos OS Release 13.2X51-D20 for QFX Series devices.
Description Display information about which packet fields are used by the hashing algorithm to make
hashing decisions.
You can configure the fields that are inspected by the hashing algorithm to make hashing
decisions for traffic entering a LAG bundle using the forwarding-options enhanced-hash-key
statement.
