z/VM TCP/IP VSWITCH Controller Maintenance
Virtual Switch Controller Maintenance Levels
The z/VM TCP/IP stack plays an important role in the Virtual Switch. It initializes the OSA-Express device used by the VSWITCH, and continues to communicate with the OSA-Express as the status changes, such as when a new guest host couples to the virtual switch.
For this reason, maintenance of the TCP/IP stack is important to virtual switch operation.
- z/VM 7.2.0 Maintenance Levels
- z/VM 7.1.0 Maintenance Levels
- z/VM 6.4.0 Maintenance Levels (At End of Service)
If you are using virtual switches, you need to stay current with CP maintenance for the virtual switch.
For general z/VM TCP/IP maintenance, see z/VM TCP/IP APARs.
How to determine your current Maintenance Level
- Use the QUERY VSWITCH command to identify the name of the
virtual switch controller.
- Use the
NETSTAT TCP controller LEVEL command to display
information
about the TCPIP MODULE. Controller is the name of the
virtual switch controller from step 1.
- Use the TCPSLVL TCPIP MODULE fm command for the TCPIP MODULE in use by controller. In the display look for the latest APAR applied to TCTOOSD, which is of particular interest for virtual switch controllers.
