如上所示命令調用下面兩個驅動接口獲取端口狀態
Void port_info_init(int unit, int port, bcm_port_info_t *info, uint32 actions)
int bcm_port_selective_get(int unit, bcm_port_t port, bcm_port_info_t *info)
Actions = BCM_PORT_ATTR_ALL_MASK
2.2 獲取端口的轉發狀態
BCM.0> debug bcm api

...
API: bcm_stg_stp_get(0,1,55,...) -> 0 Ok
Forward: ge,xe,hg
如上所示，調用驅動接口獲取端口stp 狀態。
bcm_stg_stp_get(int unit, bcm_stg_t stg, bcm_port_t port, int *stp_state)
2.3 設置端口的轉發狀態

命令在調用驅動接口
bcm_stg_stp_set( int unit, bcm_stg_t stg, bcm_port_t port, int stp_state)
設置端口ge15 stp 狀態為Block之后，查看端口狀態，顯示為block，打入廣播報文，其他端口沒有廣播報文統計計數。

修改L2_user_entry 表index 為3的表項，mac 為0x000000000003，從block 的ge12打入構造的目的mac為0x03的二層報文，其他端口有統計計數。
或者通過如下方式增加L2_user_entry表項

優先級映射實現從QoS優先級到內部優先級或從內部優先級到QoS優先級的映射，並利用DiffServ域來管理和記錄QoS優先級和服務等級之間的映射關系。
對於進入設備的報文，將報文攜帶的優先級或者端口優先級映射為內部優先級，然后根據內部優先級與隊列之間的映射關系確定報文進入的隊列，從而針對隊列進行流量整形、擁塞避免、隊列調度等處理，並可以根據配置修改報文發送出去時所攜帶的優先級，以便其他設備根據報文的優先級提供相應的QoS服務。
對報文進行優先級標記，可以打在二層報文上，也可以在三層(ip)報文頭上。

10. 問題及解決方法
以大於200p/s發送二層廣播報文時出現發送流控問題，此時cpu口在vlan 1內，將cpu口從vlan中移除，不會發送流控，對於需要上送cpu的報文可以通過添加L2 Entry表項或設置寄存器或ACL規則上送，此外需要配置cpu上送報文限速。

通過添加L2 Entry，目的mac為cpu mac的ICMP報文實現上送
BCM.0>L2 add mac=02:10:18:db:88:47 vlan=1 pbm=cpu0 Static=true ReplacePriority=false Replace=false L3=true
2. 寄存器配置ARP報文上送
BCM.0> sc ArpReplyToCpu=1
BCM.0> sc ArpRequestToCpu=1
3. 通過FP規則配置EtherType 為0x0806的ARP報文上送cpu
配置如下：
BCM.0> fp init
BCM.0> fp qset add EtherType
BCM_FIELD_QSET_ADD(EtherType) okay
BCM.0> fp group create 0 0
BCM.0> fp entry create 0 1
BCM.0> fp qual 1 EtherType 0x0806 0xfff
BCM.0> fp action add 1 CopyToCPU 0 0
BCM.0> fp entry install 1
BCM.0> fp show

函數sh_init 中，對從rc.soc中讀取到的，或通過命令下發的init soc, init bcm , init mmu, init all 進行處理，下發init bcm時，調用bcm_init 函數。
在_bcm_modules_init中，完成各個模塊的初始化。
首先，初始化tx, rx ，然后注冊驅動功能處理函數指針，實現根據芯片類型dispatch到對應的處理。
如下為_bcm_modules_init 中處理流程：
而由bcm_init 調用到bcm_esw_init 是通過dispatch 實現的。
Src/bcm/Control.c 中的bcm_init 調用函數指針_dispatch_init[BCM_DTYPE(unit)](unit); 分發到具體的芯片處理初始化函數。
在src/bcm/Control.c中，定義宏BCM_DLIST_ENTRY 參數為_dtype 時，聲明的外部函數為
Int bcm_##_dtype##_init(int);
#define BCM_DLIST_ENTRY(_dtype)\
extern int bcm_##_dtype##_init(int);
#include <bcm_int/bcm_dlist.h>
#define BCM_DLIST_ENTRY(_dtype)\
bcm_##_dtype##_init,
static int (*_dispatch_init[])(int) = {
#include <bcm_int/bcm_dlist.h>
};
在bcm_dlist.h 中，定義
#ifdef BCM_ESW_SUPPORT
BCM_DLIST_ENTRY(esw)
#endif
這樣，支持esw類型的芯片（Helix4）調用_dispatch_init 時，就分發到bcm_esw_init 函數處理。
和芯片初始化相關的函數定義在Src/bcm/Control.c中，和功能相關的函數定義在src/bcm/Dispatch.c中。
上面為一次分發調用過程，此外還有多次分發調用過程。
例如src/bcm/Dispatch.c 中的bcm_l3_init，首先分發到src/bcm/esw/L3.c 中的bcm_esw_l3_init，在其中再調用
mbcm_driver[unit]->mbcm_l3_tables_init(unit),
mbcm_l3_tables_init 是一個函數指針，在src/bcm/esw/Mbcm.c 的mbcm_init 中，通過
mbcm_driver[unit] = &mbcm_firebolt_driver;
將函數指針數組mbcm_firebolt_driver 賦值給mbcm_driver，這樣，調用mbcm_l3_tables_init就會調用到函數指針數組中對應的bcm_xgs3_l3_tables_init 。
