nwmgr_igssn: nwmgr - network interface management command for igssn
driver
SYNOPSIS
all
number]
Remarks
The and commands are deprecated. These commands will be removed in a
future HP-UX release. HP recommends the use of replacement command
nwmgr(1M) to perform all network interface-related tasks.
DESCRIPTION
The program is the unified command to administer all LAN and RDMA-based
interfaces of HP-UX. General information about the command as a whole
can be found in the manual page nwmgr(1M). This manual page describes
as applied to the driver.
The driver is a HP-UX Guest driver that manages Ethernet interfaces.
Each interface has several attributes. Some, such as MTU, are config‐
urable while others are read-only. In general, each attribute can have
a certain value in the running system (which is its current value),
another value in the configuration file that stores data across boots
(its saved value) and a HP-supplied value that is applied by the driver
after boot (its default value) before the saved value is applied. The
list of attributes is documented in the section named Attributes below.
The command can be used on interfaces to display information (with the
option, which is the default), modify settings (the option), reset the
interface or its statistics (the option), and to diagnose link connec‐
tivity (the option).
Operations other than require the authorization. For more information
about authorizations and Role-based Access Control, see rbac(5).
The settings of the interfaces on the system can be saved to the con‐
figuration file so that these settings will take effect across reboots.
The output in each case can be obtained in either human-readable form
(which is the default) or in a script-friendly parseable form (with the
or option). The format for script-friendly output is described in the
manpage nwmgr(1M).
It is guaranteed that any change in the scriptable output across
releases will contain only additions, never modifications 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 igssn interface.
Operation to perform Critical Resource Analysis on the interface.
Operation to diagnose/test link connectivity.
Operation to get/display interface settings.
Operation to display help information.
Operation to reset interface or statistics.
Operation to set the attributes of the interface.
Options
The command provides the following options for the interface. For more
information about these options, refer to nwmgr(1M).
Operation to assign attributes for the operation.
Attributes that can be used for interfaces are described in the
section below.
Specifies the target interface on which the operation is to be per‐
formed.
For the target interface is of the form:
where PPA is the physical point of attachment.
Specifies the configuration from which the operation will copy data.
The option takes or as argument.
Specifies how many test frame to send during a
operation. The default is 1.
Specifies a generic target qualifier was used to specify a subsystem
specific target qualifier.
The arguments supported for are
Provides more information on the instance of the
subsystem; such as, the hardware path, feature capabili‐
ties, current feature settings, the assigned NMID,
speed, and MTU of the card.
Specifies the target subsystem for the operation.
For subsystem, the option argument will always be
Specifies that the operation has to be performed on the
saved configuration (per
sistent store).

the target.
Option to display more details in the output.
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.
Maximum Ethernet payload size, in bytes.
MTU above 1500 is allowed only when the speed is 1
Gbps.
Minimum: 257
Maximum: 9000
Default: 1500
Specifies the packet size in bytes of each test frame.
The default packet size is current MTU-3. Only
valid for the operation.
This can be used to enable or disable TCP Packet Reassem‐
bly.
Values: Off, On
Default: On
USAGE
Display Network Interfaces
This command displays netowrk interface without any argu‐
ments.
The command without any arguments displays all the
network interfaces in the system, including physi‐
cal LAN interfaces (NICs), virtual LAN interfaces
(VLANs and APA aggregates), and RDMA-based inter‐
faces.
View Basic Properties of One or More Interfaces
The following command displays basic properties of inter‐
faces
The form without the verbose option displays a ta‐
ble, with one row for each interface that gets
listed. If an interface is specified as a target
with the option, only that interface gets dis‐
played. If the option is specified, all igssn
interfaces are displayed. The properties dis‐
played for each interface are explained in
nwmgr(1M).
Note that the operation is the default, so the
option need not be specified explicitly.
The verbose option changes the output to include
more details about each interface that is dis‐
played, 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 autonego‐
tiation of the interface. More details can be
found in the section.
View Interface Statistics
The following command displays interface statistics.
The option can take zero or more of the following
arguments:
The MIB statistics of the interface are displayed.
This is the default if no argument is provided to
The extended MIB statistics are displayed.
This overrides the argument, if present.
Displays the subsystem-specific statistics, which
can vary from one
driver to another.
Displays both extended MIB statistics and subsys‐
tem-specific statistics;
in other words, it is equivalent to It
overrides any other arguments that may be
present.
It is possible to give more than one argument to
the option, as a comma-separated list. For exam‐
ple, displays both the specified sets of statis‐
tics.
View Interface Attributes
These commands can be used to view interface attributes.
These commands display the current value of either
all the attributes of the interface (when the key‐
word 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.
View Interface Details
These commands display interface details.
This form displays interface-specific properties
that are informational, often not configurable and
subject to variation across drivers.
It first displays the verbose listing for the
interface; same as what is shown by:
It then displays PCI-related properties such as
the PCI Device ID. It also displays the current
driver state for the specified interface.
Set Current Values of Attributes
These commands can be used to set current values of
attributes with user specified values.
You can set current values of attributes by speci‐
fying the values with these commands.
Save Attribute Values as Default Values for an Interface
These commands can be used to set current attribute val‐
ues from default values.
Save the current values of all attributes of an
interface in the configuration file
This form stores the current value of each
attribute of an interface in the configuration
file, so that the interface configuration is pre‐
served across boots. The user can also run the
start-up script later by hand to apply the config‐
uration file values to the running kernel, by typ‐
ing:
This feature allows a user to experiment with the
current values and, when a desired configuration
is achieved, preserve it for posterity.
Set Current Attribute Values from Default
These commands sets the current values for attributes
from the default values.
The current values of all attributes of an inter‐
face (if is specified) or the specified attributes
(if the names are listed) are set to be equal to
their respective default values. This can be use‐
ful in rolling all the changes made to an inter‐
face since the time the system booted.
Reset an Interface
These commands reset an interface.
The interface is subjected to a PCI reset, which
clears all previous state, including the interface
statistics. The interface is then re-programmed
with the attribute values that were current 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 performs a Critical Resource
Analysis (CRA) to see if the interface is data-
critical; in other words, any other resource
depends for its functionality on the availability
of the interface. If so, the reset is not per‐
formed.
The reset can be forced, even if the interface is
data-critical, by using the option. It is possible
for an interface to be system-critical; in other
words, the health of the system depends on the
availability of the interface. In that case, the
reset will not be performed even if the option is
specified.
Reset Statistics for an Interface
The following commands resets the 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 unmodi‐
fied.
Diagnose Link Connectivity
This command is run 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 is 1.
The attribute specifies the size of each test
frame; the default is 100 bytes.
The attribute specifies how many seconds to wait
for the acknowledgement of each test frame; the
default is 5 seconds.
RETURN VALUES
0 The command returns 0 on success.
<>0 On failure, the command returns values described in
the section below. section below.
ERRORS
Attempt to set a read-only attribute.
The interface is presently inaccessible.
This is usually because the interface is
part of an APA aggregate, which prevents
setting attributes on the interface.
One or more of the attributes or options is invalid for
the task.
Memory allocation failed. This could be a transient con‐
dition.
Operation or feature is not supported.
The target interface could not be accessed.
The user lacks the authorization
which is required for this operation.
The specified values of one or more attributes was less
than the minimum or
more than the maximum.
