For 100Base-T, it is essential that the link partner has the same speed, duplex
and auto-negotiation settings as the NIC being configured. The speed can be
forced to 10 or 100 Mbps, with Full or Half Duplex, with auto-negotiation off.
This is done by setting speed to one of
10HD, 10FD, 100HD,or100FD (case
insensitive). The valid values allowed for
speed in the command line for
100Base-T are:
10HD, 10FD, 100HD,
100FD, and auto_on.
The valid values to set for speed for the 100Base-FX are
100FD and 100HD.
Note that 10 Mbps and auto-negotiation are not supported speed configurations
for the PCI 100Base-FX card.
The output for the speed attribute can take one of the two formats. In the
human-readable format, it is of the form:
speed {
Full | Half} Duplex (
Autonegotiation :
{On | Off})
Example:
100 Mbps Full Duplex (Autonegotiation : On)
.
In the script-friendly output, the speed value is of the form:
speed {
FD | HD} auto_{on|of}
Examples:
100FD auto_on
100HD auto_off
Note that in both formats, the speed and duplex attributes 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 auto-negotiation. For 100Base-T, the
HP_BTLAN_SPEED variable can contain one of the following values
10HD,
10FD, 100HD, 100FD, and auto_on (same as the command line values). The
HP_BTLAN_AUTONEG variable is of no relevance when HP_BTLAN_SPEED is
set. For PCI 100Base-FX, the HP_BTLAN_AUTONEG variable is irrelevant.
timeout=seconds Specifies how many seconds to wait for acknowledgement of each test frame (for
the diagnose operation). The default is 5 seconds.
USAGE
Display Network Interfaces
The most basic command to display network interface information.
nwmgr
The command without any argument displays all the network interfaces in the system, including phy-
sical LAN interfaces (NICs), virtual LAN interfaces (VLANs and APA aggregates and failover groups),
and RDMA interfaces.
View Basic Properties of Interfaces
The following command can be used to view the basic properties of one or more interfaces.
nwmgr [-g][-v][-c lan_instance | -S btlan]
nwmgr [--get][--verbose][--class_instance lan_instance | --subsystem btlan]
Note that the get operation is the default, so the -g option need not be specified explicitly.
If an interface is specified as a target with the -c option, only that interface gets displayed. If the -S
option is specified, all btlan interfaces are displayed. The properties displayed for each interface are
explained in nwmgr(1M).
The command without the verbose option displays a table, with one row for each interface that gets
listed.
The verbose option (--verbose) changes the output to include more details about each interface
displayed, and also changes the format to be line-oriented, with each line describing one property.
The following attributes are displayed: mac, mtu, and speed.
More details on these attributes can be found in the Attributes section.
