Description

(QFX10000 switches only) Select which packet header data to use for per-flow load balancing.

Note:

You can configure either Layer 3 or Layer 4 load balancing, or both at the same time.

Note:

On I chip platforms, an unknown Layer 4 header is excluded from load-balance hashing to avoid undesired packet reordering.

Options

inet—IPv4 address family.
layer-3—Incorporate Layer 3 data into the hash key.
layer-4—Incorporate Layer 4 data into the hash key.
outer-vlan-id—Include outer VLAN ID information in the hash key.
inner-vlan-id—Include inner VLAN ID information in the hash key.
payload—Incorporate payload data into the hash key.
ip—Include the IP address of the IPv4 or IPv6 payload into the hash key.
layer-3–only—Include only Layer 3 IP information.

Required Privilege Level

system—To view this statement in the configuration.

system-control—To add this statement to the configuration.
