Cisco Interface Range Configuration
During configuration of a new user access switch or other device with a switchport module, it can be beneficial to range all of the ports with a default configuration to ensure uniformity and save time. The following example enters a range configuration for FastEthernet ports 1-48. You may need to modify FastEthernet to your own port type such as GigabitEthernet, and you also may need to modify the port numbers if you have a different amount or are saving some for trunk links.
