vlanconfig - Configures or displays virtual Local Area
Network (VLAN) interfaces
For creating a VLAN interface, use the following syntax:
/usr/sbin/vlanconfig -c interface-id
[attribute,attribute,...]
For deleting a VLAN interface, use the following syntax:
/usr/sbin/vlanconfig -d interface-id
For displaying VLAN information, use the following syntax:
/usr/sbin/vlanconfig -s interface-id
Creates a VLAN virtual interface. The interface-id is the
VLAN virtual interface name in the form vlann, where n is
the unit number (for example, vlan1). It must be unique
among all VLAN virtual interfaces on the system. You must
specify the following attributes (separated by commas) to
this option: Specifies the name of the lower interface
(for example, ee0) on which to configure a VLAN virtual
interface; the VLAN virtual interface is logically above
interface-name. Specifies the identifier of the VLAN in
which to participate. This VLAN ID is contained in IEEE
802.1q tagged Ethernet frames. The ID must be unique among
all VLAN virtual interfaces configured on the same lower
interface. If you specify the ID attribute, do not specify
the untagged attribute. Indicates that the VLAN virtual
interface will use untagged frames. A lower interface
can have only one untagged VLAN virtual interface
created on it. If you specify the untagged attribute, do
not specify the id attribute. Deletes the specified VLAN
virtual interface. Displays the attributes for the specified
VLAN virtual interface or an interface on which VLANs
have been configured.
The vlanconfig command allows you to perform the following
tasks: Create VLAN virtual interfaces. Display attributes
for a specified VLAN virtual interface or an interface on
which VLANs have been configured. Delete VLAN virtual
interfaces.
A VLAN provides the administrator with the ability to create
logical groups of systems that can communicate as if
they were on the same LAN. Multiple VLANs can exist on the
same physical network. Traffic between VLANs is
restricted. Bridges forward all traffic, including broadcast
traffic, only to LAN segments that serve the VLAN to
which the traffic belongs.
You enable a network interface to participate in a particular
VLAN by creating a VLAN virtual interface. Upperlayer
software uses these VLAN virtual interfaces.
If you want to enable an interface for VLAN, you must not
configure an IP address on the interface, either through
the Network Setup Wizard (netconfig) or SysMan. You must
configure IP addresses on the VLAN virtual interfaces.
Modifications made with the vlanconfig command do not persist
across reboots of the operating system. To configure
the interface or modify the parameters automatically each
time the system is booted, edit the inet.local file and
add the vlanconfig command and ifconfig command entries to
it.
Any user can query the status of a VLAN; only the superuser
can create and modify the configuration of network
interfaces.
To enable ee0 to participate in VLAN 12 using the vlan12
virtual interface, enter: vlanconfig -c vlan12
on=ee0,id=12 To enable ee0 to also participate in VLAN
1004 using the vlan4 virtual interface, enter: vlanconfig
-c vlan4 on=ee0,id=1004 To enable ee0 to also receive
untagged frames the vlan0 virtual interface, enter: vlanconfig
-c vlan0 on=ee0,untagged To enable a NetRAIN set
with the virtual interface number of nr3 to participate in
VLAN 44 using the vlan44 virtual interface, enter: vlanconfig
-c vlan44 on=nr3,id=44
Note
Both ee0 and nr3 must not have an IP address configured
prior to issuing the vlanconfig -c command.
To display information about the vlan4 virtual
interface, enter: vlanconfig -s vlan4
VLAN interface vlan4 on ee0, untagged To verify
that the ee0 interface is in use by VLAN,
enter: vlanconfig -s ee0
interface ee0 is in use by VLAN. To configure
IP address 10.1.2.3 on the VLAN virtual interface
vlan12 and bring the interface up, enter: ifconfig
vlan12 10.1.2.3 up To remove virtual interface
vlan12, enter: vlanconfig -d vlan12
Note
The vlan12 virtual interface must not have an IP
address configured and must not be UP prior to
issuing the vlanconfig -d command.
You specified an invalid VLAN ID when you used the
id=vlan-id attribute. Valid VLAN IDs are from 1 to 4094,
inclusive. You specified a VLAN ID that was already in
use on the lower interface when you used the id=vlan-id or
the untagged attribute. You specified an interface that
was either already reserved or on which IP addresses were
already configured when you used the on=interface-name
attribute. You attempted to create a VLAN virtual interface
that already exists. You specified a non-Ethernet
interface when you used the on=interface-name attribute.
You specified a nonexistent interface for the -d or -s
option. You tried to use the -c or -d option, but were
not superuser.
