MPCOSA Device Properties

When defining a Multipath Channel Open Systems Adapter (MPCOSA) connection, use to specify the transport resource list element (TRLE) of a High Performance Data Transfer (HPDT) connection. MPCOSA devices have an ARP offload function that offloads all ARP processing to the OSA-2 adapter. TCP/IP cannot display any ARP cache information or ARP counter statistics for these devices because OSA-2 does not provide this data to TCP/IP. MPCOSA devices cannot be configured to accept IP packets destined to an IP address other than the IP address of the OSA-2 adapter. For example, IP packets destined to a Virtual IP Address (VIPA) owned by this TCP/IP will not be delivered by the OSA-2 adapter.
