link partner that is capable of running at 1 Gbps and is itself set to autonego-

tiate. In any case, the NIC does not support the half-duplex mode at speeds of

1 Gbps.

In summary, the valid values to set for speed in the command line for

1000Base-T are:

10HD, 10FD, 100HD,

100FD and auto_on.

The speed value can take one of three formats. In the human-readable for-

mat, it is of the form:

[speed {

Full | Half} Duplex

](Autonegotiation :

{On | Off})

Example:.

1 Gbps Full Duplex (Autonegotiation : On)

Note that the speed and duplex may not be present in some situations.

In the script-friendly output, the speed value is of the form:

[speed {

FD|HD}]

auto_{on|off}

Examples:

1000FD auto_on, 100HD auto_off.

Note that the speed and duplex are optional: they may not be present in some

situations.

In the conﬁguration ﬁle, there is an additional twist, because there are

separate variables for speed-duplex and autonegotiation. For 1000Base-T, the

HP_GELAN_SPEED variable can contain one of the values

10HD, 10FD,

100HD, 100FD, and auto_on (same as the command line values). The

HP_GELAN_AUTONEG variable is of no relevance.

For 1000Base-SX, the HP_GELAN_SPEED is irrelevant, while the

HP_GELAN_AUTONEG has values of either 0 or 1, indicating autonegotiation

being off or on, respectively.

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.

USAGE

Display Network Interfaces

This command displays network 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 gelan]

nwmgr [--get][--verbose][--class_instance lanPPA | --subsystem gelan]

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 gelan 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 found in the Attributes section.
