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
• crc32LSB: Use CRC32_LOWER — LSB 16 bits of computed CRC32
• crc-upper: Uses the upper 32 bits of the key for the hash computation
• dest-ip: Uses the destination IP for ECMP hashing
• flow-based-hashing: Enter the keywords flow-based-hashing followed by
the algorithm
