CONFIGURATION mode
hash-algorithm [ecmp{crc16|crc16cc|crc32LSB|crc32MSB|crc-upper|dest-ip|lsb|xor1|xor2|xor4|
xor8|xor16}]
Example of the hash-algorithm Command
Dell(conf)#hash-algorithm ecmp xor 26 lag crc 26 nh-ecmp checksum 26
Dell(conf)#
The hash-algorithm command is specific to ECMP group. The default ECMP hash configuration is crc-lower. This command takes the
lower 32 bits of the hash key to compute the egress port. Other options for ECMP hash-algorithms are:
• crc16 — uses 16 bit CRC16-bisync polynomial
• crc16cc — uses 16 bit CRC16 using CRC16-CCITT polynomial
• crc32LSB — uses LSB 16 bits of computed CRC32
• crc32MSB — uses MSB 16 bits of computed CRC32(default)
• 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 — uses the least significant bit of the hash key to compute the egress port.
• xor1 — uses Upper 8 bits of CRC16-BISYNC and lower 8 bits of xor1
• xor2 — Upper 8 bits of CRC16-BISYNC and lower 8 bits of xor2
• xor4 —Upper 8 bits of CRC16-BISYNC and lower 8 bits of xor4
• xor8 — Upper 8 bits of CRC16-BISYNC and lower 8 bits of xor8
• xor16 — uses 16 bit XOR.

Bulk Configuration

Bulk configuration allows you to determine if interfaces are present for physical interfaces or configured for logical interfaces.

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 the interface range prompt.
NOTE: When creating an interface range, interfaces appear in the order they were entered and are not sorted.
The show range command is available under Interface Range mode. This command allows you to display all interfaces that have been
validated under the interface range context.
The show configuration command is also available under Interface Range mode. This command allows you to display the running
configuration only for interfaces that are part of interface range.
You can avoid specifying spaces between the range of interfaces, separated by commas, that you configure by using the interface
range command. For example, if you enter a list of interface ranges, such as interface range fo 1/1/1-6,te 1/11/1, this
