API Call Reference List of APIs
Fundamental to the use of L2 address table entries is an opaque type, which is
used to communicate the L2 entry to the BCM5680 device.
struct arl_t {
unsigned int flags; /* BCM_L2_XXX flags */
unsigned char mac[6];/* 802.3 MAC address */
unsigned short vid; /* VLAN identifier */
int port; /* Zero-based port number */
int tgid; /* Trunk group ID */
int rtag; /* Trunk port select formula */
int cos_dst; /* COS based on dst addr */
int cos_src; /* COS based on src addr */
} arl_t;
In other API routines, either a MAC address (unsigned char *) and/or
VLAN ID (int) are used for manipulation of the address table.
int bcm_l2_addr_remove_by_port(int unit, unsigned int pbmp, unsigned int flags)
DESCRIPTION Removes all L2 (MAC) addresses associated with the port
INCLUDE src/tulsi_drivers/bcm_cli_kern/arl.h
INPUT
unit StrataSwitch PCI device unit number (driver internal)
pbmp Bitmap of ports to affect
flags BCM_L2_REMOVE_XXX
RETURN VALUE
BCM_E_NONE (Success)
BCM_E_INTERNAL (Chip access Failure)
Note: Static entries are removed only if BCM_L2_REMOVE_STATIC
flag is used.
Note: ARL aging and learning on all ports is disabled during this operation.
If these were not disabled, the hardware could shift the contents of
