Using lanadmin to Delete 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 example, 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 displays the

applications and commands that use or are conﬁgured on the interface.

Lets take another example. Before deleting, the interface lan5001, check

if there are any applications running on it by typing:

lanadmin -p 5001
