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 |
crc32LSB | crc-
upper | dest-ip |
lsb | xor1 | xor2 |
xor4 | xor8 | xor16
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
• lsb: Returns the LSB of the key as the hash
• xor1: Use CRC16_BISYNC_AND_XOR1 — Upper 8 bits of
CRC16-BISYNC and lower 8 bits of xor1
• xor2: Use CRC16_BISYNC_AND_XOR2 — Upper 8 bits of
CRC16-BISYNC and lower 8 bits of xor2
• xor4: Use CRC16_BISYNC_AND_XOR4 — Upper 8 bits of
CRC16-BISYNC and lower 8 bits of xor4
• xor8: Use CRC16_BISYNC_AND_XOR8 — Upper 8 bits of
CRC16-BISYNC and lower 8 bits of xor8
• xor16: Use CR16 — 16 bit XOR
