• 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,te 2/1/1, this configuration 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 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
• Overlap Port Ranges
