Managing your 10GbE RoCE Express interfaces

The TCP/IP stack dynamically creates 10GbE RoCE Express® interfaces for each configured PCI Express function ID (PFID). The stack activates all the configured 10GbE RoCE Express interfaces when the first SMC-R capable IPAQENET or IPAQENET6 interface is started. After the 10GbE RoCE Express interfaces are started, they remain active even when all SMC-R capable IPAQENET and IPAQENET6 interfaces are stopped. You can explicitly stop a 10GbE RoCE Express interface by using the VARY TCPIP,,STOP command. The name of the dynamically created 10GbE RoCE Express interfaces is in the form EZARIUTpffff, where p is the port number and ffff is the PFID.

Restriction: If you manually stop a 10GbE RoCE Express interface, you must later restart that interface by using the VARY TCPIP,,START command. The stack does not automatically restart the 10GbE RoCE Express interface when the next SMC-R capable interface is started.

In addition to stopping and starting the 10GbE RoCE Express interface, you can dynamically add or delete PFIDs from your TCP/IP profile by using the VARY TCPIP,,OBEYFILE command.
