These release notes describe IRIS ATM release 2.3.10. IRIS
ATM is a network interface controller (board and software)
providing Asynchronous Transfer Mode (ATM) with ATM
adaptation layer 5 (AAL5) protocol mapping over Synchronous
Optical Network (SONET) connectivity at 155.52 megabits per
second (OC3c) for Silicon Graphics Origin 3000, Onyx 3000,
Origin 2000, Onyx2, Origin 200 GIGAchannel, CHALLENGE, POWER
CHALLENGE, Onyx, and POWER Onyx servers and supercomputers.
IRIS ATM supports both permanent virtual channels (PVCs) and
switched virtual channels (SVCs). For SVCs, the product
complies with the ATM Forum's ATM User-Network Interface
standard, versions 3.0 and 3.1. The product supports
constant bit rate (CBR) and best effort traffic, and
supports use of peak cell rate, sustainable cell rate, and
maximum burst size on the transmission channels. IRIS ATM
supports IP-over-ATM in compliance with RFC 1577 and RFC
1755. The encapsulation method for carrying network
interconnect traffic over ATM AAL5 conforms to RFC 1483.
In addition, IRIS ATM supports SPANS (Simple Protocol for
ATM Network Signaling) on the Origin and Onyx2 platforms.
The driver supports all standard IP applications through
SVCs using a best effort traffic contract. The driver also
supports a character device application programming
interface (API) for customer-developed applications. This
API supports PVCs (both IP and non-IP) and non-IP SVCs.
Note: Packaged with this software is a separate sheet that
contains the Software License Agreement. This
software is provided to you solely under the terms
and conditions of the Software License Agreement.
Please take a few moments to review the Agreement.
IRIS ATM can be installed onto the following platforms:
Origin 3000, Onyx 3000, Origin 2000, Onyx2, Origin 200
GIGAchannel, CHALLENGE and POWER CHALLENGE L, CHALLENGE and
POWER CHALLENGE XL, Onyx and POWER Onyx Deskside, and Onyx
and POWER Onyx Rackmount.

Each IRIS ATM board provides four bi-directional links that
support multiple simultaneous virtual channel connections,
which can be a mix of permanent (PVC) and switched (SVC)
channels. The IRIS ATM board interfaces to the system
through the XIO interconnect, requiring one XIO slot.
Multiple IRIS ATM boards can be installed; the exact number
- 2 -
depends on the platform.
1.2 _C_H_A_L_L_E_N_G_E__a_n_d__O_n_y_x
Each IRIS ATM board provides one bi-directional link that
supports multiple simultaneous virtual channel connections,
which can be a mix of permanent (PVC) and switched (SVC)
channels. The IRIS ATM board interfaces to the operating
system through the IBus, requiring one mezzanine slot on any
IO4 board.
IRIS ATM is designed for installation by authorized service
personnel only.

IRIS ATM software is a set of applications, a driver, and
ATM protocol modules that must be built into the system's
installed operating system. The currently installed
operating system (_e_o_e) must be version 6.5 for installation
of IRIS ATM to proceed. The _v_e_r_s_i_o_n_s command, as shown
below, can be used to determine the version of the currently
running IRIX. This IRIS ATM release requires the operating
system release shown in the example below:
% versions eoe
I eoe _d_a_t_e Execution Only Environment, 6.5
1.5 _H_a_r_d_w_a_r_e__R_e_q_u_i_r_e_m_e_n_t_s
The installed IRIS ATM-OC3c 4Port XIO board must be version
030-0948-003, or later. Prior versions of the IRIS ATM-OC3c
4Port XIO board are not compatible with IRIS ATM 2.3.x
software. The board's version is indicated by a tag placed
near the board's XIO connector on the tall-component side.
The installed IRIS ATM-OC3c board (for CHALLENGE/Onyx) must
be version 030-0570-007, Rev.B, or later. Prior versions of
the IRIS ATM-OC3c board are not compatible with IRIS ATM
2.3.x software due to their lack of a MAC address. The
board's version is indicated by a tag placed near the
board's IBus connector on the component side.
For the IRIS ATM software to operate, the IRIS ATM hardware
must be installed and connected to one of the following: to
another ATM system, to an ATM switch, or to itself (using a
loopback cable). In order to use SVCs, the adjacent system
must support ATM UNI signalling. In order for the IRIS ATM
ILMI module to operate, the adjacent system must be running
an ATM ILMI module that complies with ATM UNI 3.0 or 3.1.
Note: When connected via a loopback cable, the hardware
verification utility (atmtest) can be used to test
- 5 -
the board's functionality, but upper-layer
applications cannot be verified, since they route
through the operating system's loopback interface
(lo0) whenever the destination address is local.
1.6 _P_r_o_d_u_c_t__R_e_l_e_a_s_e__L_i_m_i_t_a_t_i_o_n_s
IRIS ATM does not support loading the miniroot over the ATM
connection; Silicon Graphics computers cannot be booted over
ATM. This limitation does not affect loading the miniroot
over an Ethernet network. A system can boot (load the
miniroot) over its Ethernet network, and, thereafter,
function with both Ethernet and ATM network connections.
Note: There are special configuration requirements for
booting over the network. See Section 2.3,
``Configuring a Diskless Station.''
