Example of the hash-algorithm Command
The hash-algorithm command is specic to ECMP group. The default ECMP hash conguration 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:
Bulk Conguration
Bulk conguration allows you to determine if interfaces are present for physical interfaces or congured 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 conguration excludes from conguration any non-existing interfaces from an interface range. A default VLAN may be congured only
if the interface range being congured 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 oers 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
conguration only for interfaces that are part of interface range.
You can avoid specifying spaces between the range of interfaces, separated by commas, that you congure by using the interface
range
command. For example, if you enter a list of interface ranges, such as interface range fo 2/50-2/53,te 1/1, this
conguration is considered valid. The comma-separated list is not required to be separated by spaces in between the ranges. You can
associate multicast MAC or hardware addresses to an interface range and VLANs by using the mac-address-table static
multicast-mac-address vlan vlan-id output-range interface command.
Bulk Conguration Examples
Use the interface range command for bulk conguration.
