load-balance enable

Use this command to enable load-balancing configurations in hardware.

Use the no option to reset the load balancing to default settings.

When the command load-balance enable is issued, the default load-balance settings are unset. User then has to configure the new load-balancing parameters.

Command Syntax

This form unsets load balancing globally:

Copy 
load-balance enable

This form resets load balancing globally to default settings:

Copy 
no load-balance enable

By default, load balancing is enabled for ECMP and LAG.

This form sets hashing based on IPv4 fields:

Copy 
load-balance (ipv4 {src-ipv4 | dest-ipv4 | srcl4-port | destl4-port | protocol-id})
no load-balance (ipv4 {src-ipv4 | dest-ipv4 | srcl4-port | destl4-port | protocol-id})

This form sets hashing based on IPv6 fields:

Copy 
load-balance (ipv6 {src-ipv6 | dest-ipv6 | srcl4-port | destl4-port | protocol-id | next-hdr})
no load-balance (ipv6 {src-ipv6 | dest-ipv6 | srcl4-port | destl4-port | protocol-id | next-hdr})

This form sets hashing based on L2 fields:

Copy 
load-balance (l2 {dest-mac|src-mac|ether-type|vlan})
no load-balance (l2 {dest-mac|src-mac|ether-type|vlan})

This form sets hashing on an MPLS fields:

Copy 
load-balance (mpls {labels})
no load-balance (mpls {labels})

Following additional parameters are supported on Dune DNX boards:

Copy 
load-balance inner-ipv4 ({non-symmetric| protocol-id| src-dest-ipv4})
no load-balance inner-ipv4 ({non-symmetric| protocol-id| src-dest-ipv4})
 
load-balance inner-l2 ({ether-type| non-symmetric| src-dest-mac| vlan})
no load-balance inner-l2 ({ether-type| non-symmetric| src-dest-mac| vlan}) 

load-balance src-dest-l4port (non-symmetric)
no load-balance src-dest-l4port

The configured load balancing parameters are global and will be applicable to all LAG & ECMP created in the hardware.
