下面是配置IOS系统Catalyst交换机接口的通用流程，适用于所有接口配置过程。
（1）在特权模式提示下键入“configure terminal”（可以简写成“con t”）命令，进入全局配置模式。按回车键入显示如下提示。并要注意，此时提示符已发生了改变，从特权模式提示符“#”改变为“(config)#”。
Switch# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)#
（2）在全局配置模式下键入“interface”命令，并且标识接口类型、交换机堆叠成员号（非可堆叠交换机不用此标识）、接口号。在此以堆叠成员1的千兆以太网端口1为例（交换机为非模块交换机，模块号默认为“0”）。
Switch(config)# interface gi1/0/1
Switch(config-if)#
【注意】在接口类型和接口号之间可以留空格，也可以不留空格。当然可以是接口类型全称，也可以是简写。如gigabitethernet 1/0/1、gigabitethernet1/0/1、gi 1/0/1或者gi1/0/1都是正确的。
下面是一个综合以上2两步，进入交换机的Fast Ethernet interface 5/5接口配置模式的示例。
Switch# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)# interface fastethernet 5/5
Switch(config-if)#
（3）接着，你可以使用各种interface接口配置命令来配置相应接口，如定义接口上的协议和应用。配置完后可用end命令或者按Ctrl-Z组合键返回到特权模式。
你也可以使用“interface range”或者“interface range macro”全局配置命令来配置接口范围。但在接口范围中的接口类型必须一致，而且必须以相同的特性选项进行配置。具体在下节介绍。
（4）在你配置好一个接口后，可以在特权模式下使用show命令查看、校验对应或者所有接口配置信息是否正确。在特权模式下使用“show interfaces”命令来查看所有接口的列表。如下是一个使用命令查看所有接口配置信息的输出，从中可以得到详细的各个接口属性配置信息及工作状态。
