Parameters Defaults Command Modes Command History Usage Information algorithm-number ecmp hash algorithm value lag hash algorithm value nh-ecmp hash algorithm value linecard number ip-sa-mask value ip-da-mask value Enter the algorithm number. Range: 0 to 47 EtherScale range: 0 to 15; 16 to 47 will be considered as 15. TeraScale and ExaScale Only: Enter the keyword ecmp followed by the ECMP hash algorithm value. Range: 0 to 47 TeraScale and ExaScale Only: Enter the keyword lag followed by the LAG hash algorithm value. Range: 0 to 47 (OPTIONAL) Enter the keyword nh-ecmp followed by the ECMP hash algorithm value. (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 (OPTIONAL) Enter the keyword ip-sa-mask followed by the ECMP/ LAG hash mask value. Range: 0 to FF Default: FF (OPTIONAL) Enter the keyword ip-da-mask followed by the ECMP/ LAG hash mask value. Range: 0 to FF Default: FF 0 for hash-algorithm value on TeraScale and ExaScale IPSA and IPDA mask value is FF for line card CONFIGURATION Version 8.3.19.0 Version 8.3.10.0 Version 8.1.1.0 Version 7.8.1.0 Version 7.7.1.1 Version 6.5.1.0 Version 6.3.1.0 Introduced on S4820T Introduced on S4810 Introduced on E-Series ExaScale Added nh-ecmp option Added nh-ecmp option Added support for the line card option on TeraScale only Added the support for ECMP and LAG on TeraScale only 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.
