Usage
Information
Set the default hash-algorithm method on ExaScale systems to ensure CRC is not
used for LAG. For example,
hash-algorithm ecmp xor lag checksum nh-ecmp
checksum
To achieve the functionality of hash-align on the ExaScale platform, do not use CRC
as a hash-algorithm method.
algorithm-number Enter the algorithm number.
Range: 0 to 47
EtherScale range: 0 to 15; 16 to 47 will be considered as 15.
ecmp hash algorithm
value
TeraScale and ExaScale Only: Enter the keyword ecmp followed by the
ECMP hash algorithm value.
Range: 0 to 47
lag hash algorithm
value
TeraScale and ExaScale Only: Enter the keyword lag followed by the
LAG hash algorithm value.
Range: 0 to 47
nh-ecmp hash
algorithm value
(OPTIONAL) Enter the keyword nh-ecmp followed by the ECMP hash
algorithm value.
linecard number
(OPTIONAL) TeraScale and ExaScale Only: Enter the keyword
linecard followed by the linecard slot number.
Range: 0 to 13 on an E1200/E1200i, 0 to 6 on an E600/E600i, and 0 to 5
on an E300
ip-sa-mask value
(OPTIONAL) Enter the keyword ip-sa-mask followed by the ECMP/
LAG hash mask value.
Range: 0 to FF
