DESCRIPTION

The dladm command is used to administer data-links. A data-link is represented in the system as a STREAMS DLPI (v2) interface which can be plumbed under protocol stacks such as TCP/IP. Each data-link relies on either a single network device or an aggregation of devices to send packets to or receive packets from a network.

Each dladm subcommand operates on one of the following objects:

link

A datalink, identified by a name. A name is a maximum of 30 characters. The first character must be alphabetic, the last numeric.

Some subcommands operate only on certain types or classes of datalinks. For those cases, the following object names are used:

phys-link

A physical datalink.

vlan-link

A VLAN datalink.

aggr-link

An aggregation datalink (or a key; see NOTES).

ether-link

A physical Ethernet datalink.

wifi-link

A WiFi datalink.

dev

A network device, identified by concatenation of a driver name and an instance number.

secobj

A secure object, identified by an administratively-chosen alphanumeric name.

SUBCOMMANDS

The following subcommands are supported:

dladm show-link [-P] [-s [-i interval]] [[-p] -o field[,...]][link]

Show link configuration information (the default) or statistics, either for all datalinks or for the specified link link. By default, the system is configured with one datalink for each known network device.

-o field[,...], --output=field[,...]

A case-insensitive, comma-separated list of output fields to display. When not modified by the -s option (described below), the field name must be one of the fields listed below, or the special value all to display all fields. By default (without -o), show-link displays all fields.

LINK

The name of the datalink.

CLASS

The class of the datalink. dladm distinguishes between the following classes:

phys

A physical datalink. The show-phys subcommand displays more detail for this class of datalink.

aggr

An IEEE 802.3ad link aggregation. The show-aggr subcommand displays more detail for this class of datalink.

vlan

A VLAN datalink. The show-vlan subcommand displays more detail for this class of datalink.

MTU

The maximum transmission unit size for the datalink being displayed.

STATE

The link state of the datalink. The state can be up, down, or unknown.

OVER

The physical datalink(s) over which the datalink is operating. This applies to aggr and vlan classes of datalinks. A VLAN is created over a single physical datalink, and an aggregation is comprised of one or more physical datalinks.

When the -o option is used in conjunction with the -s option, used to display link statistics, the field name must be one of the fields listed below, or the special value all to display all fields

LINK

The name of the datalink.

IPACKETS

Number of packets received on this link.

RBYTES

Number of bytes received on this link.

IERRORS

Number of input errors.

OPACKETS

Number of packets sent on this link.

OBYTES

Number of bytes received on this link.

OERRORS

Number of output errors.

-p, --parseable

Display using a stable machine-parseable format. The -o option is required with -p. See "Parseable Output Format", below.

-P, --persistent

Display the persistent link configuration.

-s, --statistics

Display link statistics.

-i interval, --interval=interval

Used with the -s option to specify an interval, in seconds, at which statistics should be displayed. If this option is not specified, statistics will be displayed only once.

dladm rename-link [-R root-dir] link new-link]

Rename link to new-link. This is used to give a link a meaningful name, or to associate existing link configuration such as link properties of a removed device with a new device. See the EXAMPLES section for specific examples of how this subcommand is used.

-R root-dir, --root-dir=root-dir

Specifies an alternate root directory where the link rename operation should apply.

dladm show-dev [-s [-i interval]] [[-p] -o field[,...]] [dev]

Show device configuration information (the default) or statistics, either for all network devices or for the specified device dev. This subcommand is being superseded by show-phys.

-o field, --output=field

A case-insensitive, comma-separated list of output fields to display. The field name must be one of the fields listed below, or the special value all, to display all fields. For each device, the following fields can be displayed:

DEV

The name of the device.

STATE

The state of the link. This is up, if the link is running and all required resources are allocated, or down otherwise.

SPEED

The current speed of the link, in megabits per second.

DUPLEX

For Ethernet links, the full/half duplex status of the link is displayed if the link state is up. The duplex is displayed as unknown in all other cases.

-p, --parseable

Display using a stable machine-parseable format. The -o option is required with -p. See "Parseable Output Format", below.

-s, --statistics

Display network device statistics.

-i interval, --interval=interval

Used with the -s option to specify an interval, in seconds, at which statistics should be displayed. If this option is not specified, statistics will be displayed only once.

dladm delete-phys phys-link

This command is used to delete the persistent configuration of a link associated with physical hardware which has been removed from the system. See the EXAMPLES section.

dladm show-phys [-P] [[-p] -o field[,...]] [phys-link]

Show the physical device and attributes of all physical links, or of the named physical link. Without -P, only physical links that are available on the running system are displayed.

-o field, --output=field

A case-insensitive, comma-separated list of output fields to display. The field name must be one of the fields listed below, or the special value all, to display all fields. For each link, the following fields can be displayed:

LINK

The name of the datalink.

MEDIA

The media type provided by the physical datalink.

STATE

The state of the link. This can be up, down, or unknown.

SPEED

The current speed of the link, in megabits per second.

DUPLEX

-p, --parseable

Display using a stable machine-parseable format. The -o option is required with -p. See "Parseable Output Format", below.

-P, --persistent

This option displays persistent configuration for all links, including those that have been removed from the system. The output provides a FLAGS column in which the r flag indicates that the physical device associated with a physical link has been removed. For such links, delete-phys can be used to purge the link's configuration from the system.

dladm create-aggr [-t] [-R root-dir] [-P policy] [-L mode] [-T time] [-u address] -l ether-link1 [-l ether-link2...] aggr-link

Combine a set of links into a single IEEE 802.3ad link aggregation named aggr-link. The use of an integer key to generate a link name for the aggregation is also supported for backward compatibility. Many of the *-aggr subcommands below also support the use of a key to refer to a given aggregation, but use of the aggregation link name is preferred. See the NOTES section for more information on keys.

-l ether-link, --link=ether-link

Each Ethernet link (or port) in the aggregation is specified using an -l option followed by the name of the link to be included in the aggregation. Multiple links are included in the aggregation by specifying multiple -l options. For backward compatibility with previous versions of Solaris, the dladm command also supports the using the -d option (or --dev) with a device name to specify links by their underlying device name. The other *-aggr subcommands that take -loptions also accept -d.

-t, --temporary

Specifies that the aggregation is temporary. Temporary aggregations last until the next reboot.

-R root-dir, --root-dir=root-dir

Specifies an alternate root directory where dladm should apply persistent creation.

-P policy, --policy=policy

Specifies the port selection policy to use for load spreading of outbound traffic. The policy specifies which dev object is used to send packets. A policy is a list of one or more layers specifiers separated by commas. A layer specifier is one of the following:

L2

Select outbound device according to source and destination MAC addresses of the packet.

L3

Select outbound device according to source and destination IP addresses of the packet.

L4

Select outbound device according to the upper layer protocol information contained in the packet. For TCP and UDP, this includes source and destination ports. For IPsec,, this includes the SPI (Security Parameters Index.)

For example, to use upper layer protocol information, the following policy can be used:

-P L4

To use the source and destination MAC addresses as well as the source and destination IP addresses, the following policy can be used:

-P L2,L3

-L mode, --lacp-mode=mode

Specifies whether LACP should be used and, if used, the mode in which it should operate. Supported values are off, active or passive.

-T time, --lacp-timer=time

Specifies the LACP timer value. The supported values are short or longjjj.

-u address, --unicast=address

Specifies a fixed unicast hardware address to be used for the aggregation. If this option is not specified, then an address is automatically chosen from the set of addresses of the component devices.

dladm modify-aggr [-t] [-R root-dir] [-P policy] [-L mode] [-T time] [-u address] aggr-link

Modify the parameters of the specified aggregation.

-t, --temporary

Specifies that the modification is temporary. Temporary aggregations last until the next reboot.

-R root-dir, --root-dir=root-dir

dladm create-vlan [-ft] [-R root-dir] -l ether-link -v vid [vlan-link]

Create a tagged VLAN link with an ID of vid over Ethernet link ether-link. The name of the VLAN link can be specified as vlan-link. If the name is not specified, a name will be automatically generated (assuming that ether-link is namePPA) as:

<name><1000 * vlan-tag + PPA>

For example, if ether-link is bge1 and vid is 2, the name generated is bge2001.

-f, --force

Force the creation of the VLAN link. Some devices do not allow frame sizes large enough to include a VLAN header. When creating a VLAN link over such a device, the -f option is needed, and the MTU of the IP interfaces on the resulting VLAN must be set to 1496 instead of 1500.

FLAGS

A set of flags associated with the VLAN link. Possible flags are:

f

The VLAN was created using the -f option to create-vlan.

i

The VLAN was implicitly created when the DLPI link was opened. These VLAN links are automatically deleted on last close of the DLPI link (for example, when the IP interface associated with the VLAN link is unplumbed).

Additional flags might be defined in the future.

-p, --parseable

Display using a stable machine-parseable format. The -o option is required with -p. See "Parseable Output Format", below.

-P, --persistent

Display the persistent VLAN configuration rather than the state of the running system.

dladm scan-wifi [[-p] -o field[,...]] [wifi-link]

Scans for WiFi networks, either on all WiFi links, or just on the specified wifi-link.

By default, currently all fields but BSSTYPE are displayed.

-o field[,...], --output=field[,...]

A case-insensitive, comma-separated list of output fields to display. The field name must be one of the fields listed below, or the special value all to display all fields. For each WiFi network found, the following fields can be displayed:

LINK

The name of the link the WiFi network is on.

ESSID

The ESSID (name) of the WiFi network.

BSSID

Either the hardware address of the WiFi network's Access Point (for BSS networks), or the WiFi network's randomly generated unique token (for IBSS networks).

SEC

Either none for a WiFi network that uses no security, wep for a WiFi network that requires WEP (Wired Equivalent Privacy), or wpa for a WiFi network that requires WPA (Wi-Fi Protected Access).

MODE

The supported connection modes: one or more of a, b, or g.

STRENGTH

The strength of the signal: one of excellent, very good, good, weak, or very weak.

SPEED

The maximum speed of the WiFi network, in megabits per second.

BSSTYPE

Either bss for BSS (infrastructure) networks, or ibss for IBSS (ad-hoc) networks.

-p, --parseable

Display using a stable machine-parseable format. The -o option is required with -p. See "Parseable Output Format", below.

dladm connect-wifi [-e essid] [-i bssid] [-k key,...] [-s none | wep | wpa] [-a open|shared] [-b bss|ibss] [-c] [-m a|b|g] [-T time] [wifi-link]

Connects to a WiFi network. This consists of four steps: discovery, filtration, prioritization, and association. However, to enable connections to non-broadcast WiFi networks and to improve performance, if a BSSID or ESSID is specified using the -e or -i options, then the first three steps are skipped and connect-wifi immediately attempts to associate with a BSSID or ESSID that matches the rest of the provided parameters. If this association fails, but there is a possibility that other networks matching the specified criteria exist, then the traditional discovery process begins as specified below.

The discovery step finds all available WiFi networks on the specified WiFi link, which must not yet be connected. For administrative convenience, if there is only one WiFi link on the system, wifi-link can be omitted.

Once discovery is complete, the list of networks is filtered according to the value of the following options:

-e essid, --essid=essid

Networks that do not have the same essid are filtered out.

-b bss|ibss, --bsstype=bss|ibss

Networks that do not have the same bsstype are filtered out.

-m a|b|g, --mode=a|b|g

Networks not appropriate for the specified 802.11 mode are filtered out.

-k key,..., --key=key, ...

Use the specified secobj named by the key to connect to the network. Networks not appropriate for the specified keys are filtered out.

-s none|wep|wpa, --sec=none|wep|wpa

Networks not appropriate for the specified security mode are filtered out.

Next, the remaining networks are prioritized, first by signal strength, and then by maximum speed. Finally, an attempt is made to associate with each network in the list, in order, until one succeeds or no networks remain.

In addition to the options described above, the following options also control the behavior of connect-wifi:

-a open|shared, --auth=open|shared

Connect using the specified authentication mode. By default, open and shared are tried in order.

-c, --create-ibss

Used with -b ibss to create a new ad-hoc network if one matching the specified ESSID cannot be found. If no ESSID is specified, then -c -b ibss always triggers the creation of a new ad-hoc network.

-T time, --timeout=time

Specifies the number of seconds to wait for association to succeed. If time is forever, then the associate will wait indefinitely. The current default is ten seconds, but this might change in the future. Timeouts shorter than the default might not succeed reliably.

-k key,..., --key=key,...

In addition to the filtering previously described, the specified keys will be used to secure the association. The security mode to use will be based on the key class; if a security mode was explicitly specified, it must be compatible with the key class. All keys must be of the same class.

For security modes that support multiple key slots, the slot to place the key will be specified by a colon followed by an index. Therefore, -k mykey:3 places mykey in slot 3. By default, slot 1 is assumed. For security modes that support multiple keys, a comma-separated list can be specified, with the first key being the active key.

dladm disconnect-wifi [-a] [wifi-link]

Disconnect from one or more WiFi networks. If wifi-link specifies a connected WiFi link, then it is disconnected. For administrative convenience, if only one WiFi link is connected, wifi-link can be omitted.

-a, --all-links

Disconnects from all connected links. This is primarily intended for use by scripts.

dladm show-wifi [[-p] -o field,...] [wifi-link]

Shows WiFi configuration information either for all WiFi links or for the specified link wifi-link.

-o field,..., --output=field

A case-insensitive, comma-separated list of output fields to display. The field name must be one of the fields listed below, or the special value all, to display all fields. For each WiFi link, the following fields can be displayed:

LINK

The name of the link being displayed.

STATUS

Either connected if the link is connected, or disconnected if it is not connected. If the link is disconnected, all remaining fields have the value --.

ESSID

The ESSID (name) of the connected WiFi network.

BSSID

Either the hardware address of the WiFi network's Access Point (for BSS networks), or the WiFi network's randomly generated unique token (for IBSS networks).

SEC

Either none for a WiFi network that uses no security, wep for a WiFi network that requires WEP, or wpa for a WiFi network that requires WPA.

MODE

The supported connection modes: one or more of a, b, or g.

Combinations of speed and duplex values available. The units of speed are encoded with a trailing suffix of G (Gigabits/s) or M (Mb/s). Duplex values are encoded as f (full-duplex) or h (half-duplex).

PAUSE

Flow control information. Can be no, indicating no flow control is available; tx, indicating that the end-point can transmit pause frames, but ignores any received pause frames; rx, indicating that the end-point receives and acts upon received pause frames; or bi, indicating bi-directional flow-control.

REM_FAULT

Fault detection information. Valid values are none or fault.

By default, all fields except REM_FAULT are displayed for the "current" PTYPE.

The current (or persistent) property value. If the value is not set, it is shown as --. If it is unknown, the value is shown as ?. Persistent values that are not set or have been reset will be shown as -- and will use the system DEFAULT value (if any).

DEFAULT

The default value of the property. If the property has no default value, -- is shown.

POSSIBLE

A comma-separated list of the values the property can have. If the values span a numeric range, min - max might be shown as shorthand. If the possible values are unknown or unbounded, -- is shown.

The list of properties depends on the link type and network device driver, and the available values for a given property further depends on the underlying network hardware and its state. General link properties are documented in the LINK PROPERTIES section. However, link properties that begin with "_" (underbar) are specific to a given link or its underlying network device and subject to change or removal. See the appropriate network device driver man page for details.

-c, --parseable

Display using a stable machine-parseable format. The -o option is required with this option. See "Parseable Output Format", below.

-P, --persistent

Display persistent link property information

-p prop, ..., --prop=prop, ...

A comma-separated list of properties to show. See the sections on link properties following subcommand descriptions.

dladm create-secobj [-t] [-R root-dir] [-f file] -c class secobj

Create a secure object named secobj in the specified class to be later used as a WEP or WPA key in connecting to an encrypted network. The value of the secure object can either be provided interactively or read from a file. The sequence of interactive prompts and the file format depends on the class of the secure object.

Currently, the classes wep and wpa are supported. The WEP (Wired Equivalent Privacy) key can be either 5 or 13 bytes long. It can be provided either as an ASCII or hexadecimal string -- thus, 12345" and "0x3132333435 are equivalent 5-byte keys (the 0x prefix can be omitted). A file containing a WEP key must consist of a single line using either WEP key format. The WPA (Wi-Fi Protected Access) key must be provided as an ASCII string with a length between 8 and 63 bytes.

This subcommand is only usable by users or roles that belong to the "Network Link Security" RBAC profile.

-c class, --class=class

class can be wep or wpa. See preceding discussion.

-t, --temporary

Specifies that the creation is temporary. Temporary creation last until the next reboot.

-R root-dir, --root-dir=root-dir

Specifies an alternate root directory where dladm should apply persistent creation.

-f file, --file=file

Specifies a file that should be used to obtain the secure object's value. The format of this file depends on the secure object class. See the EXAMPLES section for an example of using this option to set a WEP key.

dladm delete-secobj [-t] [-R root-dir] secobj[,...]

Delete one or more specified secure objects. This subcommand is only usable by users or roles that belong to the "Network Link Security" RBAC profile.

-t, --temporary

Specifies that the deletions are temporary. Temporary deletions last until the next reboot.

-R root-dir, --root-dir=root-dir

Specifies an alternate root directory where dladm should apply persistent deletions

dladm show-secobj [-P] [[-p] -o field[,...]] [secobj,...]

Show current or persistent secure object information. If one or more secure objects are specified, then information for each is displayed. Otherwise, all current or persistent secure objects are displayed.

By default, current secure objects are displayed, which are all secure objects that have either been persistently created and not temporarily deleted, or temporarily created.

For security reasons, it is not possible to show the value of a secure object.

-o field,..., --output=field

A case-insensitive, comma-separated list of output fields to display. The field name must be one of the fields listed below. For displayed secure object, the following fields can be shown:

OBJECT

The name of the secure object.

CLASS

The class of the secure object.

-p, --parseable

Display using a stable machine-parseable format. The -o option is required with -p. See "Parseable Output Format", below.

-P, --persistent

Display persistent secure object information

Parseable Output Format

Many dladm subcommands have an option that displays output in a machine-parseable format. The output format is one or more lines of colon (:) delimited fields. The fields displayed are specific to the subcommand used and are listed under the entry for the -o option for a given subcommand. Output includes only those fields requested by means of the -o option, in the order requested.

When you request multiple fields, any literal colon characters are escaped by a backslash (\) before being output. Similarly, literal backslash characters will also be escaped (\\). This escape format is parseable by using shell read(1) functions with the environment variable IFS=: (see EXAMPLES, below). Note that escaping is not done when you request only a single field.  

General Link Properties

The following general link properties are supported:

zone

Specifies the zone to which the link belongs. This property can be modified only temporarily through dladm, and thus the -t option must be specified. To modify the zone assignment such that it persists across reboots, please use zonecfg(1M). Possible values consist of any exclusive-IP zone currently running on the system. By default, the zone binding is as per zonecfg(1M).

autopush

Specifies the set of STREAMS modules to push on the stream associated with a link when its DLPI device is opened. It is a space-delimited list of modules.

The optional special character sequence [anchor] indicates that a STREAMS anchor should be placed on the stream at the module previously specified in the list. It is an error to specify more than one anchor or to have an anchor first in the list.

The autopush property is preferred over the more general autopush(1M) command.

Wifi Link Properties

The following WiFi link properties are supported. Note that the ability to set a given property to a given value depends on the driver and hardware.

channel

Specifies the channel to use. This property can be modified only by certain WiFi links when in IBSS mode. The default value and allowed range of values varies by regulatory domain.

powermode

Specifies the power management mode of the WiFi link. Possible values are off (disable power management), max (maximum power savings), and fast (performance-sensitive power management). Default is off.

radio

Specifies the radio mode of the WiFi link. Possible values are on or off. Default is on.

speed

Specifies a fixed speed for the WiFi link, in megabits per second. The set of possible values depends on the driver and hardware (but is shown by show-linkprop); common speeds include 1, 2, 11, and 54. By default, there is no fixed speed.

Ethernet Link Properties

The following MII Properties, as documented in ieee802.3(5), are supported in read-only mode:

o duplex

o state

o adv_autoneg_cap

o adv_1000fdx_cap

o adv_1000hdx_cap

o adv_100fdx_cap

o adv_100hdx_cap

o adv_10fdx_cap

o adv_10hdx_cap

Each adv_ property (for example, adv_autoneg_cap) also has a read/write counterpart enable_ property (for example, enable_autoneg_cap) controlling parameters used at auto-negotiation.

In addition, the following Ethernet properties are reported:

speed

(read-only) The operating speed of the device, in Mbps.

mtu

The maximum client SDU (Send Data Unit) supported by the device. Valid range is 68-65536.

flowctrl

Establishes flow-control modes that will be advertised by the device. Valid input is one of:

no

No flow control enabled.

rx

Receive, and act upon incoming pause frames.

tx

Transmit pause frames to the peer when congestion occurs, but ignore received pause frames.

bi

Bidirectional flow control.

Note that the actual settings for this value are constrained by the capabilities allowed by the device and the link partner.

EXAMPLES

Example 1 Configuring an Aggregation

To configure a data-link over an aggregation of devices bge0 and bge1 with key 1, enter the following command:

# dladm create-aggr -d bge0 -d bge1 1

Example 2 Connecting to a WiFi Link

To connect to the most optimal available unsecured network on a system with a single WiFi link (as per the prioritization rules specified for connect-wifi), enter the following command:

# dladm connect-wifi

Example 3 Creating a WiFi Key

To interactively create the WEP key mykey, enter the following command:

# dladm create-secobj -c wep mykey

Alternatively, to non-interactively create the WEP key mykey using the contents of a file:

# umask 077
# cat >/tmp/mykey.$$ <<-EOF
12345
EOF
# dladm create-secobj -c wep -f /tmp/mykey.$$ mykey
# rm /tmp/mykey.$$

Example 4 Connecting to a Specified Encrypted WiFi Link

To use key mykey to connect to ESSID wlan on link ath0, enter the following command:

# dladm connect-wifi -k mykey -e wlan ath0

Example 5 Changing a Link Property

To set powermode to the value fast on link pcwl0, enter the following command:

# dladm set-linkprop -p powermode=fast pcwl0

Example 6 Connecting to a WPA-Protected WiFi Link

Create a WPA key psk and enter the following command:

# dladm create-secobj -c wpa psk

To then use key psk to connect to ESSID wlan on link ath0, enter the following command:

# dladm connect-wifi -k psk -e wlan ath0

Example 7 Renaming a Link

To rename the bge0 link to mgmt0, enter the following command:

# dladm rename-link bge0 mgmt0

Example 8 Replacing a Network Card

Consider that the bge0 device, whose link was named mgmt0 as shown in the previous example, needs to be replaced with a ce0 device because of a hardware failure. The bge0 NIC is physically removed, and replaced with a new ce0 NIC. To associate the newly added ce0 device with the mgmt0 configuration previously associated with bge0, enter the following command:

# dladm rename-link ce0 mgmt0

Example 9 Removing a Network Card

Suppose that in the previous example, the intent is not to replace the bge0 NIC with another NIC, but rather to remove and not replace the hardware. In that case, the mgmt0 datalink configuration is not slated to be associated with a different physical device as shown in the previous example, but needs to be deleted. Enter the following command to delete the datalink configuration associated with the mgmt0 datalink, whose physical hardware (bge0 in this case) has been removed:

# dladm delete-phys mgmt0

Example 10 Using Parseable Output to Capture a Single Field

The following assignment saves the MTU of link net0 to a variable named mtu.

# mtu=`dladm show-link -p -o mtu net0`

Example 11 Using Parseable Output to Iterate over Links

The following script displays the state of each link on the system.

# dladm show-link -p -o link,state | while IFS=: read link state; do
           print "Link $link is in state $state"
       done

NOTES

The preferred method of referring to an aggregation in the aggregation subcommands is by its link name. Referring to an aggregation by its integer key is supported for backward compatibility, but is not necessary. When creating an aggregation, if a key is specified instead of a link name, the aggregation's link name will be automatically generated by dladm as aggrkey.
