This example assumes a Fore PCA-200e series PCI OC-3 interface, which is interface hfa0, on a CLIP-only configuration. (The budget adaptors are hea0).
This document assumes FreeBSD 3.1-RELEASE. (If you have FreeBSD 3.0-RELEASE, one kernel module needs patching. Contact email@example.com for the patch).
edit your config file. Append these entries:
# Fore PCA-200 ATM options ATM_CORE options ATM_IP options ATM_UNI options ATM_SPANS device hfa0
Compile a new kernel and install as /kernel
### Basic network options: ### network_interfaces="xl0 atm0 lo0" # List of network interfaces (lo0 is l! ifconfig_atm0="inet 128.63.247.??? netmask 255.255.240.0" ### ATM interface options: ### atm_enable="YES" # Configure ATM interfaces (or NO). atm_netif_hfa0="atm 1" # Network interfaces for physical interface. atm_sigmgr_hfa0="uni31" # Signalling manager for physical interface. atm_prefix_hfa0="ILMI" # NSAP prefix (UNI interfaces only) (or ILMI). atm_macaddr_hfa0="NO" # Override physical MAC address (or NO). atm_arpserver_atm0="0x47.0005.80.007300.0000.0300.0100.0020481C095F00" # ATMAR! atm_scsparp_atm0="NO" # Run SCSP/ATMARP on network interface (or NO)! atm_pvcs="" # Set to PVC list (or leave empty). atm_arps="" # Set to permanent ARP list (or leave empty).

Reboot the system. It should just work.
Here is some sample "netstat -i" output:

Here is what some "atm show" commands reveal on a working system:
> atm show config hfa0 Intf Vendor Model Media Bus Serial No hfa0 Fore PCA-200E OC-3c PCI 4204387 MAC address = 00:20:48:40:27:63 Hardware version = 2.0.1 Firmware version = 3.0.1 > atm show interface Interface Sigmgr State hfa0 UNI 3.1 ACTIVE ATM address = 0x47.0005.80.007300.0000.0300.018c.002048402763.00 Network interfaces: atm0
TTCP tests between two FreeBSD machines deliver 80 Mbits/sec of user data bandwidth (exclusive of TCP, IP, and ATM overhead), e.g.:
ttcp -r -s -l102400 -n10240 ttcp -t -s -l10240 -n10240 126.96.36.199
If you can ping and traceroute directly to 188.8.131.52 (gw328-2 CLIP), you should change your default route to point there. Edit /etc/rc.conf:
The FreeBSD ATM code was provided by the HARP project.
NOTE: There is a very peculiar interaction (bug) when a FreeBSD machine talks to an SGI machine over ATM using TCP. This bug does not affect UDP (such as NFS), only TCP traffic. Traffic FreeBSD-to-SGI drizzles at a megabit or so, traffic SGI-to-FreeBSD goes only 35 Mbit/sec or so. So don't use an SGI for your raw peformance testing to FreeBSD.
