HP-UX VLAN Administrator's Guide, February 2007

• Direct attributes: Direct attributes are configurable attributes specific to the VLAN interface.
• Derived attributes: Derived attributes are inherited attributes of the physical interface on
which the VLAN is created.
• Associated IP attributes: Associated IP attributes are IP attributes associated with the VLAN
interface.
The following sections describe each of these types of attributes.
Direct Attributes
Table 1-5 lists the direct attributes configurable on HP-UX VLAN interfaces and their associated
values.

1 VLAN ID =0: Packets are not sent on a VLAN, but are regulated by a policy that specifies a VLAN priority. They are
given a VLAN header that contains a VLAN ID of zero (0). Switches used with HP-UX VLANs must support VLAN
ID = 0.

Default is an empty string, which displays as UNNAMED.
Derived Attributes
The following attributes of an HP-UX VLAN interface are derived from the related interface(the
physical interface) on which the HP-UX VLAN exists. These attributes are configurable not as
part of the HP-UX VLAN interface, but as part of the physical interface on which the HP-UX
VLAN interface is created.
• Interface state (up, down)
• Speed/duplex
• MAC address
• MTU
