Output Fields

Table 1: show forwarding-options hash-key Output Fields
Field Name Field Description
Hash-Mode

Current hash mode: Layer 4 header or Layer 4 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: Enable or Disable.
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.
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.
Inet Tunnel Endpoint ID

Indicates whether the GTP hashing, Inet Tunnel Endpoint ID is or is not used by the hashing algorithm: Yes or No.
Inet6 Tunnel Endpoint ID

Indicates whether the GTP hashing, Inet6 Tunnel Endpoint ID is or is not used by the hashing algorithm: Yes or No.
Incoming Interface

Indicates whether the interfaceis 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.
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

Hash Seed

A hash seed value, between 0 and 2882365321. A hash-seed prevents traffic polarization to same links on the next hop QFX switch when two are connected with LAG/ECMP.
Resilient Hash Seed A resilient hash seed value, between 0 and 2557914061.
MPLS Enabled

Indicates if MPLS is enabled under L4 routing.

VXLAN ID

A identifier (ID) that uniquely identifies the Virtual Extensible Local Area Networks (VXLAN) segment.
