C–VirtualNIC Interface Configuration and Administration<br />
VirtualNIC Interface Configuration and Administration<br />
DGID<br />
Defines the Destination Global Identifier (DGID) of the IOC to be used. This<br />
parameter should be used in all CREATE blocks. The ib_qlgc_vnic_query<br />
command will show all the DGIDs that the host can see. The DGID<br />
parameter is identified as dgid in the output of the ib_qlgc_vnic_query<br />
-e command.<br />
INSTANCE<br />
Defaults to 0. The range is 0-255. If a host connects to the same IOC more<br />
than once, each connection must be assigned a unique instance.<br />
RX_CSUM<br />
Defaults to TRUE. When true, RX_CSUM indicates that the receive<br />
checksum should be verified by the VIO hardware.<br />
HEARTBEAT<br />
Defaults to 100. Specifies the time in 1/100 of a second between the<br />
heartbeats that occur between a host and an EVIC.<br />
PORT<br />
Alternative specification for a local adapter port. The first port is 1.<br />
NOTE:<br />
If there is only one adapter in the system, then use PORT/HCA to<br />
specify the adapter port to be used. If there is more than one adapter in<br />
the system then it is recommended to use PortGuid to specify the<br />
adapter port to be used.<br />
PORTGUID<br />
The PORTGUID of the InfiniBand port to be used. Use of the PORTGUID<br />
parameter for configuring the VNIC interface has an advantage on hosts<br />
having more than 1 <strong>Host</strong> Channel Adapter. PORTGUID is persistent for a<br />
given InfiniBand port, meaning VNIC configurations should be consistent<br />
and reliable - unaffected by restarts of the OFED InfiniBand stack on host<br />
having more than 1 adapter.<br />
HCA<br />
An optional <strong>Host</strong> Channel Adapter specification for use with the PORT<br />
specification. The first adapter found by the sysem upon boot is HCA 0. If<br />
there is only one adapter in the system, then the default value of this<br />
parameter (0) can be used, so "HCA" does not need to be specified in the<br />
qlgc_vnic.cfg file. If there is more than one adapter in the system, then<br />
<strong>QLogic</strong> recommends using the PORTGUID parameter to specify an adapter<br />
port (instead of using HCA/PORT) since there is no guarantee that a system<br />
booting up always finds the same adapter first.<br />
