3.2 _N_e_w__F_e_a_t_u_r_e_s
+o SPANS (Simple Protocol for ATM Network Signaling) on
Origin/Onyx2 platforms.
3.3 _K_n_o_w_n__L_i_m_i_t_a_t_i_o_n_s
This release of the IRIS ATM software has the following
limitations.
+o Each IRIS ATM-OC3c board simultaneously supports a
maximum of 39 transmit-only and 34 receive-only virtual
channels, or 34 bidirectional VCs (for example, 34 PVCs
in the _p_v_c._c_o_n_f file for IP traffic over port 0).
+o Each IRIS ATM-OC3c 4Port XIO board simultaneously
supports a maximum of 64 transmit-only and 64 receive-
only virtual CBR channels, or 64 bidirectional CBR VCs.
The max number of bidirectional VC's is 256.
+o The IRIS ATM driver does not support IP broadcast
addresses. This means that the ATM network interfaces
(_a_t_m_0, _a_t_m_1, etc.) do not support BOOTP, NIS, RIP,
_t_i_m_e_d, _g_a_t_e_d, OSPF, and the multicast version of NTP
(which all use broadcast addresses as part of their
normal operation).
+o The IRIS ATM driver cannot function as the primary
interface on a system operating with the IP suite of
network protocols.
+o This release of IRIS ATM does not support the Raw
Network Family. Applications that use the Snoop or
Drain protocols cannot run over the _a_t_m# interfaces.
+o When the IRIS ATM driver is a leaf node at the
receiving end of a point-to-multipoint connection, it
does not support ADD_PARTY requests for that
connection. Specifically, IRIS ATM accepts the initial
SETUP request that adds the system to a multicast call,
but does not support additional requests to add that
same system to the same call.
+o On Origin/Onyx2 systems, running a multiboard maximum
bandwidth system requires the use of node cards with a
Hub ver. 2.3 or higher.
