● 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

Enter the keyword hg then one of the following options available in the stack-unit
and linecard provisioned devices:
● 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
● 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

hg-seed seed-
value
(This option is available in stack-unit and linecard provisioned devices): Enter the
keywords hg-seed then the hash algorithm seed value. The range is from 0 to
2147483646.
stack-unit
number
(OPTIONAL) : Enter the keyword stack-unit then the stack-unit slot number.
linecard number
(OPTIONAL) : Enter the keyword linecard then the linecard slot number.
port-set number
(OPTIONAL) Enter the keyword port-set then the port-set slot number.
Defaults 0 for hash-algorithm value on TeraScale and ExaScale IPSA and IPDA mask value is FF for a line card.
