Dell EMC SmartFabric OS10 User Guide Release 10.5.0

The maximum number of ECMP groups supported on the switch depends on the maximum ECMP paths configured on the switch. To view the maximum number of ECMP groups and paths, use the show ip ecmp-group details command.

OS10# show ip ecmp-group details
Maximum Number of ECMP Groups : 256
Maximum ECMP Path per Group : 64
Next boot configured Maximum ECMP Path per Group : 64

The default value for the maximum number of ECMP paths per group is 64. This value is configurable and you can configure a maximum of up to 128 ECMP paths per group.

The Maximum ECMP Path per Group is the current value configured in the hardware. The Next boot configured Maximum ECMP Path per Group is the value that is configured for maximum ECMP path and will take effect after the next reboot.

You can increase or decrease the maximum number of ECMP groups using the ip ecmp-group maximum-paths number command. The number of ECMP groups is inversely proportional to the number of ECMP paths.

To configure maximum paths per ECMP route:

OS10# configure terminal
OS10(config)# ip ecmp-group maximum-paths 10
OS10(config)# exit
OS10# write memory
OS10# reload
