dlpi_promiscon


NAME

dlpi_promiscon, dlpi_promiscoff - enable or disable DLPI promiscuous mode

SYNOPSIS

cc [ flag… ] file-ldlpi [ library… ]
#include <libdlpi.h>

int dlpi_promiscon(dlpi_handle_t dh, uint_t level);

int dlpi_promiscoff(dlpi_handle_t dh, uint_t level);

DESCRIPTION

The dlpi_promiscon() function enables promiscuous mode on a DLPI link instance associated with DLPI handle dh, at the specified level. After enabling promiscuous mode, the caller will be able to receive all messages destined for the DLPI link instance at the specified level. This operation can be performed in any DLPI state of a handle.

The dlpi_promiscoff() function disables promiscuous mode on a DLPI link instance associated with DLPI handle dh, at the specified level. This operation can be performed in any DLPI state of a handle in which promiscuous mode is enabled at the specified level.

The level modes are:

DL_PROMISC_PHYS

Promiscuous mode at the physical level

DL_PROMISC_SAP

Promiscuous mode at the SAP level

DL_PROMISC_MULTI

Promiscuous mode for all multicast addresses

The level modifier (OR’d with level) is:

DL_PROMISC_NOLOOP

Do not loopback messages to the client.

As per the DLPI standard, any message sent over _dh_ is looped back and received if it matches the level specified above. To prevent this, DL_PROMISC_NOLOOP may be OR’d into the level when calling dlpi_promiscon(). This behavior remains in effect until the promiscuous mode is disabled through dlpi_promiscoff().

RETURN VALUES

Upon success, DLPI_SUCCESS is returned. If DL_SYSERR is returned, errno contains the specific UNIX system error value. Otherwise, a DLPI error value defined in <sys/dlpi.h> or an error value listed in the following section is returned.

ERRORS

DLPI_EBADMSG

Bad DLPI message

DLPI_EINHANDLE

Invalid DLPI handle

DLPI_EINVAL

Invalid argument

DLPI_ETIMEDOUT

DLPI operation timed out
