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 configuration using the
CONFIGURATION ECMP-GROUP command mode.
hash-algorithm
Changes the hash algorithm used to distribute traffic flows across a Port Channel and ECMP. The ECMP and LAG options are supported
on the S-Series and Z-Series.
Syntax
hash-algorithm {algorithm-number | {ecmp {crc16 | crc16cc | crc32MSB | crc32LSB
| crc-upper | dest-ip | lsb | xor1 | xor2 | xor4 | xor8 | xor16} [number] hg
{crc16 | crc16cc | crc32MSB | crc32LSB | xor1 | xor2 | xor4 | xor8 | xor16}
stack-unit stack-unit-number | port-set port-pipe | hg-seed seed-value stack-
unit | lag {checksum | crc | xor} [number] nh-ecmp {checksum | crc | xor}
[number] stack—unit number ip-sa-mask value ip-da-mask value | seed seed-
value }
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.
Parameters
ecmp crc16 |
crc16cc |
crc32MSB |
Enter the keyword ecmp then one of the following options:
• crc16: Use CRC16_BISYNC — 16 bit CRC16-bisync polynomial (default)
• crc16cc: Use CRC16_CCITT — 16 bit CRC16 using CRC16-CCITT polynomial
