Usage Information
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 conguration using the
CONFIGURATION ECMP-GROUP command mode.
hash-algorithm
Changes the hash algorithm used to distribute trac ows across a Port Channel and ECMP. The ECMP and LAG options are supported
on the S-Series and Z-Series.
Syntax
hash-algorithm {ecmp {crc16 | crc16cc | crc32MSB | crc32LSB | crc-upper | dest-
ip | flow-based-hashing {crc16|crc16cc|crc32MSB|crc32LSB|xor1|xor2|xor4|xor8|
xor16}|lsb | xor1 | xor2 | xor4 | xor8 | xor16}[[hg {crc16 | crc16cc | crc32MSB
| crc32LSB | xor1 | xor2 | xor4 | xor8 | xor16}]| [lag {crc16 | crc16cc |
crc32MSB | crc32LSB | xor1 | xor2 | xor4 | xor8 | xor16 }][stack-unit|linecard
number | port-set number] | [hg—seed value] | [seedvalue]
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.
