Page 6: Bulk Interface Configuration Commands
Bulk interface configuration commands display interface range Use display interface range to display information about the interface ranges created by using the interface range name command. Syntax display interface range [ name name ] Views Any view Predefined user roles network-admin network-operator Parameters... - Page 7 Parameters interface-list: Specifies a space-separated list of up to five interface items. Each item specifies an interface by its type and number or a range of interfaces in the form of interface-type interface-number1 to interface-type interface-number2. When you specify the to keyword, the interfaces before and after the to keyword must be on the same interface card or subcard.

Page 8: Interface Range Name
[Sysname] interface range gigabitethernet 1/0 to gigabitethernet 2/0 [Sysname-if-range] shutdown interface range name Use interface range name name interface interface-list to create an interface range, configure a name for the interface range, and enter the interface range view. Use interface range name name without the interface keyword to enter the view of an interface range with the specified name. - Page 9 The maximum number of interface range names is limited only by the system resources. To • guarantee bulk interface configuration performance, H3C recommends that you configure fewer than 1000 interface range names.
