ECMP Configuration Guide

introduction introduction equal cost multi path is an important technology for improving network performance and reliability through specific algorithms, network traffic is evenly distributed to multiple links or ports, avoiding congestion on a single link or port due to excessive traffic and fully utilizing network bandwidth resources when a link fails, the switch can automatically switch traffic to other normal links to achieve redundant backup common load sharing methods include source mac, destination mac, source ip, destination ip, and their combinations, which are suitable for scenarios such as server cluster access, core layer and aggregation layer interconnection by configuring functions such as link aggregation and policy routing, switches can efficiently complete load sharing tasks, ensuring stable network operation and high speed data ecmp configure ecmp configure default setting default setting table 1 load balancing default setting table 1 load balancing default setting true 169,437 left #4283c7 unhandled content type left #4283c7 unhandled content type left unhandled content type left unhandled content type left #d8e5f5 unhandled content type left #d8e5f5 unhandled content type left unhandled content type left unhandled content type left #d8e5f5 unhandled content type left #d8e5f5 unhandled content type configure load balancing mode configure load balancing mode table 2 configure load balancing mode table 2 configure load balancing mode true 261,211 5,133 5 left #4283c7 unhandled content type left #4283c7 unhandled content type left #4283c7 unhandled content type left unhandled content type left unhandled content type left unhandled content type left #d8e5f5 unhandled content type left #d8e5f5 unhandled content type left #d8e5f5 unhandled content type configure hash enhancement configure hash enhancement after configuring hash enhancement, the value of hash seed will be randomly modified on the switch with an interval of 1ms when there are multiple equivalent forwarding paths after the traffic reaches the switch, hash enhancement can be enabled to share the load of traffic on these multiple forwarding paths table 3 enable hash enhancement table 3 enable hash enhancement true 267,185 5,153 5 left #4283c7 unhandled content type left #4283c7 unhandled content type left #4283c7 unhandled content type left unhandled content type left unhandled content type left unhandled content type left #d8e5f5 unhandled content type left #d8e5f5 unhandled content type left #d8e5f5 unhandled content type
