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

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

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:

lanadmin -V modify vlanid 53 pri 3 5000

Successfully modified lan5000

Old value: vlanid 454 pri 6

New value: vlanid 53 pri 3

After the modiﬁcation, the lanscan -v output will display:
