Usage To ensure that CRC is not used for LAG, set the default hash-algorithm method.
Information For example,hash-algorithm ecmp xor lag checksum nh-ecmp
checksum.
The hash value calculated with the hash-algorithm command is unique to the
entire chassis. The hash algorithm command with the line card option changes the
hash for a particular line card by applying the mask specified in the IPSA and IPDA
fields.

• 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
