show forwarding-options enhanced-hash-key

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.

Output Fields

Table 1 lists the output fields for the show forwarding-options enhanced-hash-key command. Output fields are listed in the approximate order in which they first appear. Output fields vary by platform.

Table 1: show forwarding-options enhanced-hash-key Output Fields
Field Name	Field Description
`Hash-Mode`	Current hash mode: Layer 2 header or Layer 2 payload.
`Protocol`	Indicates whether the Protocol field is or is not used by the hashing algorithm: Yes or No.
`Destination L4 Port`	Indicates whether the Destination L4 Port field is or is not used by the hashing algorithm: Yes or No.
`Source L4 Port`	Indicates whether the Source L4 Port field is or is not used by the hashing algorithm: Yes or No.
`Destination IPv4 Addr`	Indicates whether the Destination IPv4 Addr field is or is not used by the hashing algorithm: Yes or No.
`Source IPv4 Addr`	Indicates whether the Source IPv4 Addr field is or is not used by the hashing algorithm: Yes or No.
`Incoming port`	Indicates whether the incoming port number (interface) is or is not used by the hashing algorithm. Yes or No Note: When passive monitoring is enabled on a QFX10000 Series switch interface, the `inet, inet6` and `L2` fields are all set to No.
`Vlan id`	Indicates whether the Vlan ID field is or is not used by the hashing algorithm: Yes or No.
`Inner-Vlan ID`	Indicates whether the inner Vlan field is or is not used by the hashing algorithm: Yes or No.
`Next Hdr`	Indicates whether the Next Hdr field is or is not used by the hashing algorithm: Yes or No.
`Destination IPv6 Addr`	Indicates whether the Destination IPv6 Addr field is or is not used by the hashing algorithm: Yes or No.
`Source IPv6 Addr`	Indicates whether the Source IPv6 Addr field is or is not used by the hashing algorithm: Yes or No.
`Ether Type`	Indicates whether the Ether Type field is or is not used by the hashing algorithm: Yes or No.
`Destination MAC Address`	Indicates whether the Destination MAC Address field is or is not used by the hashing algorithm: Yes or No.
`Source MAC Address`	Indicates whether the Source MAC Address field is or is not used by the hashing algorithm: Yes or No.
`Symmetric-hashing`	Indicates whether symmetric hashing is set for `inet` and `inet6`: Yes or No.
`Load Balancing Method for ALB`	Indicates the load balancing method for adaptive load balancing (ALB): flowlet or per-packet. The load balancing method is flowlet by default, and can be configured using the `fabric-load-balance` statement.
`Load Balancing Method for DLB (QFX5120-32C, QFX5120-48Y, and QFX5220 switches)`	Indicates various Dynamic Load Balancing (DLB) modes: Flowlet Assigned flow Per-packet Refer Dynamic Load Balancing for more details.
`Fabric Link Scale`	Indicates the fabric link scale, in mbps.
`Inactivity Interval`	Indicates the fabric load balance inactivity interval, in microseconds (us). The inactivity interval is 16 microseconds by default, and can be configured using the `inactivity-interval` statement.
`Hash Region Size/Trunk`	Indicates the hash region size, in buckets per fabric trunk.
`Seed`	A hash seed value, between 0 and 4294967295. If a hash-seed value is not configured it is automatically assigned on the QFX10000 Series switches. A hash-seed prevents traffic polarization to same links on the next hop QFX switch when two are connected with LAG/ECMP.
`Key`	Indicates whether the GRE key field is or is not used by the hashing algorithm: Yes or No.
`Protocol`	Indicates if a Generic Router Encapsulation (GRE) endpoint over routes was dynamically learned by a routing protocol such as RIP or OSPF.
`MPLS Enabled`	Indicates if MPLS is enabled under L2 switching.
`VXLAN VNID`	A 24-bit virtual network identifier (VNID) that uniquely identifies the Virtual Extensible Local Area Networks (VXLAN) segment.
