ERROR DESCRIPTION:
TCP/IP for VM does not report all point-to-point IP addresses to
an OSD device when it is being used in a Supernetwork
environment. The system on which this problem has been
identified was configured with a class C Supernet, as follows:
193.x.14 Subnet_Mask 0.0.1.0 Subnet_value 0
TCP/IP reports all IP addresses in the 193.x.14 range, butdoes
not report IP addresses in the 193.x.15 range.
LOCAL FIX:
PROBLEM SUMMARY:
****************************************************************
* USERS AFFECTED: All users of OSD devices *
****************************************************************
* PROBLEM DESCRIPTION: When Proxy ARP support is enabled, *
* TCP/IP may not provide all *
* point-to-point IP addresses to the OSD *
* adapter. As a result, some traffic *
* destined for hosts with point-to-point *
* connections through VM TCP/IP may not *
* be delivered. *
****************************************************************
* RECOMMENDATION: APPLY PTF *
****************************************************************
If an OSD connection is defined as part of a supernetwork, only
hosts whose point-to-point connections use the same subnetwork
as the OSD connection will have their home addresses added to
the OSD IP address table. As a result, traffic for hosts in
other parts of the supernetwork will not be directed to VM
TCP/IP for forwarding.
PROBLEM CONCLUSION:
Code has been changed to support supernetworks for OSD Proxy
ARP.
