1、broadcom交换芯片linux命令行操作执行手册1. 交换芯片的说明.内部连接图：详细介绍：目前我们716和732板上面用的是56309芯片，该芯片引出了24个GE口和4个10G口。端口号从0开始，023为GE口，2427为10G口。XLR732CPU与交换芯片的24号直连，后插板的10G口对应交换芯片的27口，上背板fabric的10G口是交换芯片的25,26两个10G口。后插板上的GE口标注的端口号和交换芯片内部不一致。 后插板上的GE口和交换芯片上端口的对应关系如下：后插板端口：12345678910111213141516芯片端口：1816141210820222321191715

2、131192. 驱动程序的组成和加载组成：目前linux下的broadcom驱动和相关文件由4部分组成：linux-kernel-bde.ko linux-bcm-core.ko bcm-netlink.ko bcm。Linux-kernel-bde.ko负责设备的枚举和DMA等，linux-bcm-core.ko负责设备的配置，Bcm-netlink.ko负责应用空间到内核空间的通讯，bcm为应用程序，提供shell下配置broadcom交换芯片的命令。加载：进入linux的shell下之后，找到3个ko模块所在的目录，然后输入如下命令：1.insmod linux-kernel-bde.k

3、o2.insmod linux-bcm-core.ko init=bcm3.insmod bcm-netlink.ko注意：必须按上面所示的顺序进行模块的加载。目前版本已经将模块设置为自动加载。3. shell下的配置命令说明(1)常用命令1.bcm show port作用：查看端口的基本状态。eg:2.bcm show stat作用：查看端口的包统计信息字段含义：PORT：端口号RPKT：收包数RMCA：收组播包数RBCA：收广播包数R64收064字节包数RBYT：收包的总字节数eg:3.bcm show stat err作用：查看端口的错包统计信息字段含义：PORT：端口号RFCS：FCS

17、r i in seq 1 4094 ; do bcm set vlan create 0 $i ; donefor i in seq 0 4095 ; do bcm set vlan tagport 0 $i 1;done因为至少有一个默认vlan存在，所以打印出了一条错误信息，错误信息的条数就是创建失败的个数,rv=-8表示要创建的vlan已经存在。bcmsetvlanscreate用法：bcmsetvlanscreateunitvlanid-vlanid作用：创建多个vlan例如：创建连续的多个vlan，vlanid为10-30bcmsetvlanscreate010-30(4)mirro

36、What we know The search for flight MH370I know that until we find the plane, many families cannot start to grieve. I cannot imagine what they must be going through. But I can promise them that we will not give up, he said.Malaysian authorities have come in for heavy criticism over their management o
