Enter the keyword hg 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
● 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 keywords stack-unit, then a stack-unit number, to specify a stack-
unit.
Enter the keywords port-set port-pipe then the port pipe number. The
range is from 0 to 5.
hg-seed seed-
value stack-unit
Enter the keywords hg-seed then the hash algorithm seed value. The range is
from 0 to 2147483646.
Enter the keywords stack-unit then the stack unit number.
Enter the keywords port-set then the stack-unit port-pipe number.
lag hash
algorithm
Enter the keywords hg-seed . The range is from 0 to 47.
nh-ecmp
hashalgorithm
value
(OPTIONAL) Enter the keyword nh-ecmp then the ECMP hash algorithm value.
stack-unit
number
(OPTIONAL) : Enter the keywordstack—unit then the stack—unit slot number.
ip-sa-mask value
(OPTIONAL) Enter the keyword ip-sa-mask then the ECMP/LAG hash mask
value. The range is from 0 to FF.
ip-da-mask value
(OPTIONAL) Enter the keyword ip-da-mask then the ECMP/LAG hash mask
value. The range is from 0 to FF.
Defaults IPSA and IPDA mask value is FF for the stack-unit.
