nwmgr_iocxgbe(1M) nwmgr_iocxgbe(1M)
Default: On
When configured, the adapter automatically generates a pause frame when the
amount of data in the receive queue exceeds a threshold.
tx_coal TX Interrupt Timer. For transmit interrupt coalescing, the minimum time between
transmit interrupts. Units in microseconds. Setting to 0 disables the timer, the
device will schedule an interrupt immediately after completing a packet transmit
request.
Min: 1
Max: 1000000
Default: 32
vmtu Virtual MTU. Virtual MTU for TCP Segmentation Offload (TSO). Setting it to zero
disables TSO. Setting it to a non-zero value enables TSO, but only if Transmit
Checksum Offload is enabled.
Values: 0, 32160
Default: 32160
rx_trace Receive perf tracing. It is used to enable/disable tracing for receive frames. This is
an internal attribute. Use --hp for set/get operations.
Values:Off,On
Default: Off
tx_trace Transmit perf tracing. It is used to enable/disable tracing for transmit frames This
is an internal attribute. Use --hp for set/get operations.
Values:Off,On
Default: Off
USAGE
The common usages of nwmgr for the iocxgbe driver are described in greater detail below. The output
format that is described is the human-readable one; references to the scriptable output are made as
necessary.
nwmgr
The command without any arguments displays all the network interfaces in the system, including
physical LAN interfaces (NICs), virtual LAN interfaces (VLANs and APA aggregates), and RDMA-
based interfaces.
View Basic Properties of One or More Interfaces
nwmgr [-g][-v][-c lanPPA | -S iocxgbe
]
nwmgr [--get][--verbose][--class_instance lan
PPA | --subsystem iocxgbe]
The form without the verbose option displays a table, with one row for each interface that gets
listed. If an interface is specified as a target with the
-c option, only that interface gets displayed.
If the -S option is specified, all iocxgbe interfaces are displayed. The properties displayed for
each interface are explained in nwmgr(1M). Note that the get operation is the default, so the -g
option need not be specified explicitly.
The verbose option changes the output to include more details about each interface that is
displayed, and also changes the format to be line-oriented, with each line describing one property.
The additional properties displayed for each interface include not only those described in
nwmgr(1M) but also the speed and duplex of the interface. More details can be found in the Attri-
butes section.

nwmgr [-g] --st [mib | extmib | subsys | all] -c lanPPA
nwmgr [--get] --stats [mib | extmib | subsys | all]
--class_instance lanPPA
The
--stats option can take zero or more of the following arguments:
mib The MIB statistics of the interface are displayed. This is the default if no argument is
provided to --stats.
