DESCRIPTION

       The  SMC protocol requires grouping of standard Ethernet and RoCE networks or ISM devices.
       Such groups are called Physical Networks (PNETs). The mapping is configured within a table
       called  pnet  table.  Any  available  Ethernet interface can be combined with an available
       RDMA-capable network interface card (RNIC) or a DMA-capable ISM device, if they belong  to
       the  same Converged Ethernet fabric. To configure mapping of a RoCE Adapter port or an ISM
       device to a standard Ethernet interface, both devices need to have the same pnetid; either
       hardware-defined or user-defined using the pnet table.  Hardware-defined pnetids cannot be
       overwritten.

       The smc_pnet command configures the pnet table.

OPTIONS

       By default, smc_pnet shows all entries of the pnet table.

       <pnetid>
              defines a name for a grouping of Ethernet interface and RNICs or  ISM  devices.   A
              pnetid name consists of up to 16 alphanumeric uppercase characters without blanks.

       -a, --add
              creates  a  new pnetid definition to the pnet table (if it does not already exist).
              Only one pnetid can  be  defined  for  a  certain  Ethernet  interface,  a  certain
              InfiniBand device port or a certain ISM device.  Adding more than one pnetid fails.
              Hardware defined pnetids cannot be overwritten.

       -s, --show
              shows a certain pnetid definition in the pnet table.

       -d, --delete
              deletes an existing pnetid definition from the pnet table.

       -f, --flush
              removes all pnetid definitions from the pnet table.

       -I, --interface <ethernet-interface>
              specifies the name of the Ethernet interface to  be  added  for  a  certain  pnetid
              definition.

       -D, --ibdevice <infiniband-or-ISM-device>
              specifies the ID of the InfiniBand device or ISM device.

       -P, --ibport <infiniband-port>
              specifies  the port number of the InfiniBand device port. Valid numbers are 1 or 2.
              The default value is 1.

       -v, --version
              displays smc_pnet program version.

       -h, --help
              displays a brief smc_pnet usage information.

EXAMPLES

       Define pnetid ABC for the ethernet device names encf500 and bond0, and define  pnetid  ABC
       for the InfiniBand device ID 0001:00:00.0 (port 2) and the ISM device ID 0004:00:00.0:

           $ smc_pnet -a ABC -I encf500
           $ smc_pnet -a ABC -I bond0
           $ smc_pnet -a ABC -D 0001:00:00:00.0 -P 2
           $ smc_pnet -a ABC -D 0004:00:00:00.0

       Show all pnet table entries:

           $ smc_pnet
           ABC encf500 n/a 255
           ABC bond0 n/a 255
           ABC n/a 0001:00:00.0 2
           ABC n/a 0004:00:00.0 1

       Define pnetid XYZ for the ethernet interface name vlan0201 and the InfiniBand
       device ID 0001:00:00.0 (port 1):

           $ smc_pnet -a XYZ -I vlan0201 -D 0001:00:00.0 -P 1

       Show all entries for pnetid XYZ:

           $ smc_pnet -s XYZ
           XYZ vlan0201 n/a 255
           XYZ n/a 0001:00:00.0 1

       Delete all pnet table entries with pnetid named ABC:

           $ smc_pnet -d ABC

       Delete all entries in the pnet table:

           $ smc_pnet -f

RETURN CODES

       Successful  smc_pnet  commands return 0.  If an error occurs, smc_pnet writes a message to
       stderr and completes with a return code other than 0.
