1 shell简介

shell即BCM Diagnostic Shell是一个普通的命令行解释器（CLI），它可以

提供对嵌入了BCM交换芯片的嵌入式平台的一种精确控制作用。shell支持所有

Broadcom交换芯片，并提供了对所有寄存器，内存和最高层API的直接访问功

能。此外，由于shell支持交互和非交互两种模式，所以它可以嵌入到客户的设

计中，以提供额外诊断服务。

Shell命令可被分为六大类：

1. 帮助命令：？？，？，help

2. 系统基本信息获取命令：Version，show

3. 常用检测命令：端口类： PORT，COMBO

收发包类： TX, PacketWatcher

程序调试类： Debug，DebugMod

4. 检测芯片的命令：寄存器的访问： Getreg，EditReg 等

内存访问：Dump, Write 等

中断管理：INTR

5. 高级配置命令： VLAN, L2, L3 等

6. 错误检测命令： Test ，CONFig，等

2 Shell的使用

以DCN DS45XX项目为例来说明shell的使用。

Help: Type help "command" for detailed command usage

Help: Upper case letters signify minimal match

Commands common to all modes:

? Display list of commands

ASSert Assert

BackGround Execute a command in the background.

BCM Set shell mode to BCM.

BCMX Set shell mode to BCMX.

break place to hang a breakpoint

CASE Execute command based on string match

CD Change current working directory

cint Enter the C interpreter

CONFig Configure Management interface

CONSole Control console options
