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 PNET ID; either hardware-defined or user-defined using the pnet table.   Hardware-defined  PNET  IDs
       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 PNET ID consists
              of up to 16 alphanumeric uppercase characters without blanks.

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

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

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

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

       -I, --interface <ethernet-interface>
              specifies the name of the Ethernet interface to be added for a certain PNET ID 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  PNET  ID  ABC  for  the  ethernet  device names encf500 and bond0, and define PNET ID 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 PNET ID 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 PNET ID XYZ:

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

       Delete all pnet table entries with PNET ID 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.
