I suggest that TCPIP be given a virtual NIC on the VSWITCH rather than dedicating an OSA for these reasons: 1. VSWITCH has better OSA stall detection than TCPIP 2. No need for dynamic routing daemon and VIPA 3. No need for additional IP addresses 4. Reduces the temptation to share OSA ports (VSWITCH + TCPIP) Alan Altmark z/VM Development IBM Endicott
