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, 22000

Default: 22000

USAGE

The common usages of

nwmgr for the

iexgbe 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 iexgbe]

nwmgr [--get][--verbose][--class_instance lan

PPA | --subsystem iexgbe]

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 iexgbe 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.

View Interface Statistics

nwmgr [-g] --st [mib | extmib | subsys | all] -c lan

PPA

nwmgr [--get] --stats [mib | extmib | subsys | all]

--class_instance lan

PPA

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.

extmib The extended MIB statistics are displayed. This overrides the mib argument, if present.

subsys Displays the subsystem-speciﬁc statistics, which can vary from one driver to another.

all Displays both extended MIB statistics and subsystem-speciﬁc statistics, in other words, it

is equivalent to extmib,subsys. It overrides any other arguments that may be

present.

It is possible to give more than one argument to the

--stats option, as a comma-separated list.

For example, --stats mib,subsys displays both the speciﬁed sets of statistics.

View Interface Attributes

nwmgr [-g] -A {all | attr1, attr2, ...} -c lanPPA

nwmgr [--get] --attribute {all | attr1, attr2, ...} --class_instance lanPPA

These commands display the current value of either all the attributes of the interface (when the

all keyword is speciﬁed) or the speciﬁed attributes (when they are listed by name). Each attribute

is listed on a separate line as a name-value pair.
