ERROR DESCRIPTION:
TCPIP connectivity may fail in an IP (Layer 3)
configuration using VLANs with a shared OSA.
This problem is most likely to occur when using two zVM TCPIP
stacks connected to a single OSA.

LOCAL FIX:
N/A
PROBLEM SUMMARY:
****************************************************************
* USERS AFFECTED: All z/VM TCP/IP users of IP (Layer 3) *
* interfaces that specify a VLAN on the LINK *
* statement utilizing a shared OSA-Express. *
****************************************************************
* PROBLEM DESCRIPTION: *
****************************************************************
* RECOMMENDATION: APPLY PTF *
****************************************************************
No connectivity or a loss of connectivity may occur in a
configuration with these conditions:
- Multiple z/VM TCP/IP stacks sharing the same OSA-Express
adapter
- IP (Layer 3) interface with an IPv4 (and optional IPV6) VLAN
- Using OSA-Express6S or OSA-Express7S on z14 or z15
D/T3906 D/T3907 D/T8561
PROBLEM CONCLUSION:
A change in the OSA-Express6S and OSA-Express7S interface
between z/VM and OSA requires that the VLAN ID be set in the
outbound data buffer. FPQDIO has been updated to set the
IPv4 and optional IPv6 VLAN ID appropriately.
