要显示ISDN基本速率接口（BRI）的信息，用show controllers bri优先EXEC命令。
show controllers bri number
show controllers bri slot/port (Cisco 7200 series)
| 语法 |
说明 |
| number |
接口号。如果路由器用8端口的BRI网络接口模块（NIM），则取值为0~7，如果路由器有两个8端口BRI NIM，则取值为0~15。接口号数值随所用的硬件平台而改变。例如，Cisco 3600系列路由器最多可有48个接口。 |
| slot/port |
接口背面的槽号和端口号。具体槽号和端口号见硬件安装手册。 |
命令方式：优先EXEC
使用指南：这个命令最初在Cisco IOS Release 10.3中出现。
这个命令在Cisco IOS Release 11.2 P中修改成包括Cisco 7200系列路由器上PA-8B-ST和PA-4B-U端口适配器的槽/端口语法。
下列样本是show controllers bri命令的输出：
Router# show controllers bri 0
BRI unit 0
