You can alternatively use the

lanadmin -V info vppa command to get information about a speciﬁc

VPPA. Let’s say you are interested in VPPA 6050. The following command will get information regarding

VPPA 6050.

#lanadmin -V info 6050

Deleting a VLAN

Before deleting a VLAN, ensure that there are no applications or upper layer protocols active on the

VLAN by running:

#lanadmin -p VPPA

This command displays the applications and commands that are presently using the interface. For exam-

ple, if the only thing done to lan5000 is conﬁgure an IP address, the

lanadmin -p command output

would look like:

#lanadmin -p 5000

ifconfig

Since

ifconfig command is used to conﬁgure an IP address the same is displayed. There are two

entries because when an IPv4 address is conﬁgured using ifconfig, it conﬁgures both IP and ARP on

the interface.

To remove the IP and ARP streams, do:

#ifconfig lan5000 unplumb

The lanadmin -p 5000 output will not show any entries now, which means the interface can be

deleted. To delete this VLAN, use the delete option as follows:

#lanadmin -V delete 5000

The lanadmin -p PPA command always displays the commands that use or are conﬁgured on the

interface. Lets take another example, to delete the interface lan5001

#lanadmin -p 5001

ifconfig

mib2agt

scopeux

In addition to IP and ARP being conﬁgured on the interface, two applications,

mib2agt and scopeux,

are using the interface. These applications are started during system bootup via the startup scripts

/sbin/rc2.d/S565SnmpMib2 and /sbin/rc2.d/S810mwa

, respectively. To stop these utilities,

run the stop sequence of the scripts. To delete the lan5001 interface, type the following commands:

#ifconfig lan5001 unplumb

#/sbin/rc2.d/S565SnmpMib2 stop

#/sbin/rc2.d/S810mwa stop

Now,

lanadmin -p 5001 will not display anything, and the interface can be deleted.

Once the interface is deleted, you can restart the script by issuing the start sequence:

#/sbin/rc2.d/S565SnmpMib2 start

#/sbin/rc2.d/S810mwa start

NOTE: The start and stop sequence of the startup scripts will affect all the interfaces on the system, and

they must be restarted once the delete operation is completed.
