nwmgr_iether(1M) nwmgr_iether(1M)
Note that speeds below 1 Gbps are allowed only if MTU is 1500 bytes or less.
tx_cko Transmit Checksum Offload: Hardware TCP/UDP (IPv4) transmit checksum
offload.
Values:Off,On
Default: Off
vmtu Virtual MTU for TCP Segmentation Offload (TSO). Setting
it to zero disables TSO. Setting it to a non-zero value enables TSO.
Values: 0, 32160
Default: 0
tx512_bufs Use this option to limit the transmit buffer size limit to 512 bytes. This option
is applicable only for PCI-X cards and is not supported on PCIe interfaces.
Use value 1 to enable and 0 to disable.
Values: 0, 1
Default: 0
USAGE
Display Network Interfaces
This command displays netowrk interface without any arguments.
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
The following command displays basic properties of interfaces
nwmgr [-g][-v][-c lanPPA | -S iether
]
nwmgr [--get][--verbose][--class_instance lan
PPA | --subsystem iether]
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 iether option is specified, all iether 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, duplex and autonegotiation of the interface. More details can be
found in the Attributes section.
View Interface Statistics
The following command displays interface statistics.
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.
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.
