Querying for a Base VPPA Value You can determine the minimum acceptable value for a Virtual PPA using the following command:

lanadmin -V basevppa Example: lanadmin -V basevppa 5000

 

Using a VLAN

 

Once a VLAN is created, its VPPA can be used to configure protocols,

 

send commands, and transmit and receive data just like a physical point

 

of attachment (PPA). For example, to configure an IP address on the

 

VLAN, type:

 

ifconfig lan5000 inet 100.2.1.1 netmask 255.255.255.0 up

 

You cannot change physical link properties such as speed, duplexity, or

NOTE

 

maximum transmission unit (MTU) over a VLAN. If you make changes

 

to a physical interface, those changes will be reflected in the VLANs on

 

that interface.

 

 

Using lanadmin to Modify a VLAN

The properties of a VLAN can be modified using lanadmin. For example, to change the VLAN ID to 53 and priority to 3, on lan5000, type:
