SYNOPSIS

       smc_pnet { -a | --add <pnetid> } { -I | --interface <ethernet-interface> }

       smc_pnet  {  -a  |  --add <pnetid> } { -D | --ibdevice <infiniband-or-ISM-device> } [ -P |
       --ibport <infiniband-port> ]

       --ibdevice <infiniband-or-ISM-device> } [ -P | --ibport <infiniband-port> ]

       smc_pnet { -s | --show <pnetid> }

       smc_pnet { -d | --delete <pnetid> }

       smc_pnet { -f | --flush }

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
