Comments
For information on the syntax and the values for the new PQUPLINKTX option added to the DirMaint NICDEF command see: SC24-6188-06 z/VM: Directory Maintenance Facility Commands Reference. The new option includes: PQUPLINKTX LOW|NORMAL|HIGH For a virtual switch with priority queueing enabled, PQUPLINKTX sets the priority for all packets sent from a NIC's network connection to an external network. If PQUPLINKTX is not specified, all outbound traffic to the external network is sent at a NORMAL priority on the virtual switch uplink port. If PQUPLINKTX is configured for a virtual switch without priority queuing enabled, the setting is saved and used if priority queuing is enabled at a later time. LOW specifies that the outbound traffic to the external network is set at a low priority. This traffic uses the low priority queue, which is serviced less frequently than the normal or high priority queues. NORMAL specifies that the outbound traffic to the external network is set at a normal priority. This traffic uses the normal priority queue, which is serviced less frequently than the high priority queue but more frequently than the low priority queue. HIGH specifies that the outbound traffic to the external network is set at a high priority. This traffic uses the high priority queue, which is serviced more frequently than the normal or low priority queues.
