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 />
