# hfa(4)

FORE Systems 200-Series ATM adapter driver

## NAME

**hfa** – FORE Systems 200-Series ATM adapter driver

## SYNOPSIS

**device** **hfa**

## DESCRIPTION

The **hfa** driver provides support for the FORE Systems ATM series 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 specifications. The supported AALs include:

- FORE AAL 0: The cell service;

- FORE AAL 4: Version three and four of AAL;

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

- *hw.atm.hfa**N**.shape* (0)

  Disable shaping on card number *N*.

- *hw.atm.hfa**N**.shape* (1)

  Set one VCI to be traffic shaped on device *N*. This will shape the first CBR VCI which is opened.

- *hw.atm.hfa**N**.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:

- FORE Systems PCA-200E ATM

- FORE Systems 200S

- FORE Systems 200

## DIAGNOSTICS

- fore\_cmd\_drain: %s%d: GET\_PROM failed

  The driver failed to drain the PROM buffer.

- fore initialization failed: intf=%s%d

  Initialization of the card has failed.

- fore initialization timed out: intf=%s%d

  Initialization of the card has timed out.

- hfa: version mismatch: fore=%d.%d kernel=%d.%d

  A version mismatch error has occurred.
