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 {ecmp | lag | seed }
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 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
• crc32MSB: Use CRC32_UPPER — MSB 16 bits of
computed CRC32
