NAME

hfa - FORE Systems 200-Series ATM adapter driver

SYNOPSIS

device hfa

DESCRIPTION

The hfa driver provides support for the FORE Systems ATM se

ries 200
adapters. This driver will support up to eight devices in a

system at
any given time. The hfa driver follows the AALI or FORE ATM

Adaptation
Layer Interface and as such will adhere to its specifica

tions. The supported AALs include:

+o FORE AAL 0: The cell service;

+o FORE AAL 4: Version three and four of AAL;

+o FORE AAL 5: Version five of AAL.

The hfa driver supports traffic shaping for cards with

firmware revisions
of 4.X.X, see fore_dnld(8). The following sysctls are rec

ognized by the
driver and may be used to enable or disable traffic shaping:

hw.atm.hfaN.shape (0)

Disable shaping on card number N.

hw.atm.hfaN.shape (1)

Set one VCI to be traffic shaped on device N. This

will shape
the first CBR VCI which is opened.

hw.atm.hfaN.shape (2)

Attempt to shape all VCIs on device N.

The firmware should be loaded before using this driver, this

can be an
easy task if the fore_dnld(8) utility is used. If the

/etc/rc.d/atm1
file has been properly configured then the firmware update

should be
automatic.

HARDWARE

The hfa driver supports the following adapters:

+o FORE Systems PCA-200E ATM
+o FORE Systems 200S
+o FORE Systems 200
