Example of the hash-algorithm Command
Dell(conf)#hash-algorithm ecmp xor1 lag crc16
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:
• 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.
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. In the following
example, 10 Gigabit 3/0 and VLAN 1000 do not exist.
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.
Bulk Configuration Examples
Use the interface range command for bulk configuration.
• Create a Single-Range
• Create a Multiple-Range
• Exclude Duplicate Entries
• Exclude a Smaller Port Range
