Info
titleNOTE:
  • Enable IP routing function before using this feature, for details please refer to Configuring IP Routing.
  • IPv6 static ECMP routing is not supported.


In L2/L3, ECMP is supported. The maximum ECMP outgoing port group is 4*128. If each ECMP route is configured to have up to 4 equal-cost paths, for example, the maximum ECMP outgoing port group support is 128. If each ECMP route is configured to have up to 16 equal-cost paths, the maximum ECMP outgoing port group support is 32. Several different ECMP routes can share the same outgoing port group. After configuring the ECMP equal-cost path maximum, reboot the switch to make it available. 

...

Info

When you configure ECMP hash mode, follow these restrictions and guidelines:

  • Dynamic Load Balancing for ECMP is only supported on Trident3 and Tomahawk3 platforms.

  • When the ECMP hash-mapping mode configuration (set/delete) changes, a system restart reboot is required for the configuration to take effect.

  • ECMP hash-mapping modes (round-robin-load-balancing, randomized-load-balancing, symmetric and dlb-normal)are mutually exclusive. To switch between modes, you must first delete the configured mode before setting up the new one. Then, restart the system for the configuration to take effect.
