Remarks
The and commands are deprecated. These commands will be removed in a
future HP-UX release. HP recommends the use of the replacement command
nwmgr(1M) to perform all network interface-related tasks.
DESCRIPTION
The program is a unified command to administer all HP-UX LAN and RDMA-
based interfaces. General information about the command as a whole can
be found in the nwmgr(1M) manpage. The nwmgr_intl100(1M) manpage
describes as applied to the driver.
The driver is one of the HP-UX drivers that manages the 100BT Ethernet
copper interfaces (100Base-TX). Each interface has several attributes.
Some attributes, such as MTU are configurable while others are read-
only. In general, each attribute can have a certain value during run
time (which is its current value), another value in the configuration
file that stores data across boots (its saved value), and an HP-sup‐
plied value that is applied by the driver after boot (its default
value) before the saved value is applied. The list of attributes is
described in the section below.
The command can be used on interfaces to display information (with the
option, which is the default), modify the settings (the option), reset
the interface or its statistics (the option), and to diagnose link con‐
nectivity (the option).
Operations other than require the authorization For more information
about authorizations and Role-based Access Control, see rbac(5).
The output in each case can be obtained in either human-readable form
(the default form) or in a script-friendly parseable form (with the or
option). The format for script-friendly output is described in the
nwmgr(1M) manpage. It is guaranteed that any change in the scriptable
output across releases will contain only additions, but not modifica‐
tions or deletions.
The human-readable format can change across releases, including modifi‐
cations and deletions, though the changes can be expected to be incre‐
mental. The usage is explained in greater detail below. The output
format that is described is the human-readable one; references to the
scriptable output are made as necessary.
Operations
The command provides the following operations for the driver.
Operation to perform Critical Resource Analysis on the interface.
Operation to diagnose/test link connectivity.
Get display interface settings.
Display help information.
Reset interface or statistics.
Set configuration information of the components and the subsystems.
Options
The command provides the following options for the driver. For more
information about these options, refere to nwmgr(1M).
Specify the parameter associated with a target whose value can be
retrieved and/or set.
Limit the scope of the operation to the LAN class.
Specifies the configuration parameter values to be used or the opera‐
tion.
The operation takes any one of or as argument.
Specifies how many test frame to send during a
operation. The default is 1.
Specifies a keyword or special identifier used by a subsystem to add
additional context for the operation being performed.
The argument supported for is which provides more information on
the instance of the subsystem; such as, the hardware path, fea‐
ture capabilities, current feature settings, the assigned NMID,
speed, and MTU of the card.
Limit the scope of the operation to the subsystem specified.
Example of a subsystem is:
Specifies that the operation applies to configuration parameter valuse
saved
in a persistent store.
Display the output in script parseable format.
Specifies that the operation applies to the statistics of the target.
Specify verbose mode
Attributes
The valid attributes for the interface are:.
Ethernet MAC address of the remote interface. Used with the operation.
Ethernet MAC Address.
The default value is the factory MAC address. This is valid for
get and set operations.
Displays the maximum Ethernet payload size (MTU), in bytes.
MTU above 1500 is not allowed.
Specifies the package size of each test frame
(for the operation). The default is 100 bytes.
The actual values of Speed, Duplex and Autonegotiation of the
Ethernet link if the link is up; otherwise, the configured val‐
ues. Note that, for 100Base-FX, the is always fixed at 100 Mbps
and the duplex can be set to either Half or Full Duplex. The
valid values allowed for in the command line for 100Base-FX are
and (case insensitive).
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 or (case insensitive). The
valid values allowed for in the command line for 100Base-T are:
and
The valid values to set for speed for the 100Base-FX are and
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 for‐
mats. In the human-readable format, it is of the form:
speed
Example:
In the script-friendly output, the speed value is of the form:
speed
Examples:
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-negotia‐
tion. For 100Base-T, the HP_BTLAN_SPEED variable can contain
one of the following values and (same as the command line val‐
ues). 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.
Specifies how many seconds to wait for acknowledgement of each
test frame (for the operation). The default is 5 seconds.
USAGE
The common usage of for interfaces are described in this section.
Display Network Interfaces
The most basic command to display network interface information.
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 Interfaces
The following command can be used to view the basic properties of one
or more interfaces.
lan_instance |
lan_instance |
Note that the operation is the default, so the option need not
be specified explicitly.
If an interface is specified as a target with the option, only
that interface is displayed. If the option is specified, inter‐
faces are displayed.
The command without the option displays a table, with one row
for each interface that is listed.
The 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 attribute. The
following attributes are displayed: and
More details on these attributes can be found in the section.
View Interface Statistics
The following command can be used to display interface statistics.
lan_instance
lan_instance
The arguments and are the only valid arguments for for drivers.
is the default if no argument is provided with It displays the
same information as which displays extended MIB statistics.
displays a subset of MIB statistics of the interface.
View Interface Attributes
The following command can be used to display the current value of
either all the attributes of the interface (when the keyword is speci‐
fied) or the specified attributes (when they are listed by name).
lan_instance
lan_instance
Each attribute is listed on a separate line as a name-value
pair.
View Interface Details
The following command can be used to get detail information about the
interface.
lan_instance
lan_instance
This form displays interface-specific properties that are infor‐
mational, often not configurable and subject to variation across
drivers. In the case of the output is same as what is shown by:
The option provides more information about the subsystem.
Set Attribute Values
The following command can be used to set values to the specified
attributes.
lan_instance
lan_instance
The attributes that can be set are: and
Save Current Attribute Values
The following command can be used to save the current attribute values
in the configuration file.
lan_instance
lan_instance
This form 'freezes' the current state of an interface; that is,
it stores the current value of each attribute of an interface in
the configuration file so that the interface configuration is
saved across boots. The user can also run the start-up script
later manually to apply the configuration file values to the
running kernel, by typing: This feature allows a user to experi‐
ment with the current values, and save the desired configura‐
tion.
Set Attribute Values from Default Values
The following command can be used to set default values to all
attributes (if is specified), or to selected attributes (if the
attribute names are listed).
lan_instance
lan_instance
This can be useful in rolling all the changes made to an inter‐
face since the time the system booted.
Reset an Interface
The following command can be used to reset an interface.
lan_instance
lan_instance
The interface is subjected to a PCI reset, which clears all pre‐
vious state, including the interface statistics. The interface
is then re-programmed with the attribute values that were cur‐
rent before the reset. Promiscuous mode and multicast addresses
are preserved across the reset.
While the reset is in progress, the data traffic through the
interface is interrupted. So, the command automatically per‐
forms a Critical Resource Analysis to see if the interface is
data-critical; that is, any other resource depends for its func‐
tionality on the availability of the interface. If so, the
reset is not performed.
The reset can be forced, even if the interface is data-critical,
by using the option. It is possible for an interface to be sys‐
tem-critical; that is, the health of the system depends on the
availability of the interface. In that case, the reset is not
be performed even if the option is specified.
Reset Statistics of an Interface
The following command can be used to reset statistics for an interface.
The data traffic statistics for an interface are cleared to
zero. This includes the byte count and packet count for inbound
and outbound traffic. Other aspects of the interface are left
unmodified.
Diagnose Link Connectivity
The following command can be used to diagnose link connectivity.
number]
number]
Link connectivity at the data link layer is checked by sending
IEEE XID test frames to the specified destination MAC address
and counting the replies.
The option specifies how many test frames to send. The default
value is 1.
The attribute specifies the size of each test frame. The
default value is 100 bytes.
The attribute specifies how many seconds to wait for the
acknowledgement of each test frame. The default value is 5 sec‐
onds.
RETURN VALUES
On success.
On failure, the command returns values in
as shown in below.
ERRORS
Below are the errors generated by on failure.
Attempt to set a read-only attribute.
The interface is currently inaccessible.
One or more of the attributes or options is invalid for the
operation.
Memory allocation failed. This could be a transient condition.
Operation or feature is not supported.
The target interface could not be accessed.
The user lacks the authorization "hpux.network.config", which is
required
for this operation.
The specified values of one or more attributes was less than the
minimum or
more than the maximum.
