ARP/ND to host

There are two levels of policy for ARP/ND to host:

Level 1: Interface-based Interface-based policies are divided into default policy and user-defined policy. The system gives priority to matching user-defined policy. If not matched, the default policy will be used. Optional actions include permit, deny, and pass. While permit and deny mean to perform ARP/ND to host route conversion and non-conversion behavior directly without matching the next level of segment policy, pass means to skip the interface policy process and enter the next level of policy.
Level 2: Segment-based Segment policy is also divided into default policy and user-defined segment policy. The system matches user-defined policy first, if not matched, then the default policy will be used. Optional actions include permit and deny, which correspond to ARP/ND to host route conversion and non-conversion behavior.

[Purpose]

Set load-balance and hash key.

[Parameters]

Parameter

Description

hash_key

The configurable hash key varys in different modes.

Keys vlan_id/ip-protocol/src-ip/dst-ip/l4-src-port/l4-dst-port/in-port are supported for type IPv4.

Keys vlan-id/src-ipv6/dst-ipv6/l4-src-port/l4-dst-port/in-port/nextheader/flow-label are supported for type IPv6.

Keys src-mac/dst-mac/ethertype/vlan-id/in-port are supported for NON-IP type.

Keys vlan_id/ip-protocol/src-ip/dst-ip/l4-src-port/l4-dst-port/in-port/bth-dest-qp supported for ipv4-rdma type.

Keys vlan-id/src-ipv6/dst-ipv6/l4-src-port/l4-dst-port/in-port/nextheader/ flow-label/bth-dest-qp supported for ipv6-rdma type.

[View]

Global Configuration View

[Notes]

Set this parameter to modify the LAG and ECMP hash key. CX308P-48Y-N-V2, CX532P-N-V2 and CX732Q-N-V2 devices currently do not support configuring flow label fields for ipv6 types, which is enabled by default. Only CX864E-N device currently supports ipv4-rdma and ipv6-rdma type. Run command no hash mode {ipv4|ipv6|non-ip|ipv4-rdma|ipv6-rdma} to delete the configured custom load balancing and restore it to the default configuration.

[Use Cases]

sonic# configure terminal
sonic(config)# hash mode ipv4 src-ip dst-ip
sonic(config)# hash mode ipv6 src-ipv6 nextheader in-port
sonic(config)# hash mode non-ip src-mac dst-mac vlan-id
