Configuring the ECMP Load Balancing Mode

Context

ECMP applies to the network where multiple links to the same destination are available. In the traditional routing technology, packets are forwarded to the destination through one link only; the other links are in backup or inactive state; switching between these links requires a certain period when dynamic routes are used. Different from the traditional routing technology, ECMP can use multiple links to increase transmission bandwidth and transmit data on a faulty link without any delay or packet loss.

Procedure

Run system-view
The system view is displayed.
Run ecmp load-balance sip [ dip ] [ port ]
The ECMP load balancing mode is set.

By default, ECMP load balancing is performed on packets based on the source IP address, destination IP address, transport-layer source port number and destination port number.

Only the S5720-EI, S5720-HI, S5730-HI, S5731-H, S5731-S, S5731S-H, S5731S-S, S5732-H, S5735-S, S5735S-S, S5735-S-I, S6720-EI, S6720-HI, S6720S-EI, S6730-H, S6730S-H, S6730-S, and S6730S-S support the ECMP load balancing mode.
Run ecmp load-balance diffluence
ECMP-based distribution of packets with the same source address and destination address is configured.

By default, ECMP-based distribution of packets with the same source address and destination address is not configured.

Only the S5720-HI, S5730-HI, S5731-H, S5731-S, S5731S-H, S5731S-S, S5732-H, S6720-HI, S6730-H, S6730S-H, S6730-S, and S6730S-S support this command.
