Dell Force10 E600i FTOS Version 8.4.1.5 Configuration Guide for ExaScale - Page 434

www.dell.com | support.dell.com The following example shows a sample configuration for the hash-algorithm command. FTOS(conf)# FTOS(conf)#hash-algorithm ecmp xor 26 lag crc 26 nh-ecmp checksum 26 FTOS(conf)# On C-Series and S-Series, the hash-algorithm command is specific to ECMP groups and has different defaults from the E-Series. The default ECMP hash configuration is crc-lower. This takes the lower 32 bits of the hash key to compute the egress port. Other options for ECMP hash-algorithms are: • crc-upper - uses the upper 32 bits of the hash key to compute the egress port • dest-ip - uses destination IP address as part of the hash key • lsb - always uses the least significant bit of the hash key to compute the egress port To change to another method, use the following command in the CONFIGURATION mode: Command Syntax hash-algorithm ecmp {crc-upper} | {dest-ip} | {lsb} Command Mode CONFIGURATION Purpose Change to another algorithm.

Interface Range An interface range is a set of interfaces to which other commands may be applied, and may be created if there is at least one valid interface within the range. Bulk configuration excludes from configuration any non-existing interfaces from an interface range. A default VLAN may be configured only if the interface range being configured consists of only VLAN ports. The interface range command allows you to create an interface range allowing other commands to be applied to that range of interfaces. The interface range prompt offers the interface (with slot and port information) for valid interfaces. The maximum size of an interface range prompt is 32. If the prompt size exceeds this maximum, it displays (...) at the end of the output. Note: Non-existing interfaces are excluded from interface range prompt. In the following example, Tengigabit 3/0 and VLAN 1000 do not exist. 434 | Interfaces
