Using CONFIGURATION mode, create an ECMP group ID. You can then assign

interfaces to the ECMP group using CONFIGURATION ECMP-GROUP mode. You

can also enable on the port-channel configuration using the CONFIGURATION

ECMP-GROUP command mode.

hash-algorithm

Changes the hash algorithm used to distribute traffic flows across a Port Channel. The ECMP and LAG

options are supported on the Z-Series.

To return to the default hash algorithm, use the no hash-algorithm command.

To return to the default ECMP hash algorithm, use the no hash-algorithm

ecmp algorithm-value command.

To remove the hash algorithm on a particular stack-unit, use the no hash-

algorithm linecard number command.
