www.dell.com | support.dell.com Parameters 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 Note: For EtherScale, range 0 to 15 is valid; 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 line card 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 Defaults 0 for hash-algorithm value on TeraScale and ExaScale IPSA and IPDA mask value is FF for line card Command Modes CONFIGURATION Command History 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 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 Usage Set the he default hash-algorithm method on ExaScale systems to ensure CRC is not used for LAG. For Information 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 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. The line card option is applicable with the lag-hash-align microcode only (refer to cam-profile (Config)). Any other microcode returns an error message as follows: 474 | Equal Cost Multi-Path
