Associated IP Attributes

HP-UX VLAN interfaces have IP attributes assigned to them the same way that physical interfaces

do. The following IP attributes are associated with HP-UX VLAN interfaces when an IP address

has been assigned to the HP-UX VLAN interface.

• IPv4 attributes

— IPv4 address

— Interface status (enable/up, disable/down)

— Subnet mask

— Broadcast address

— IPv4 alias

• IPv6 attributes

— IPv6 address

— Interface status (enable/up, disable/down)

— Prefix length

— IPv6 alias

Using VLANs with HP Serviceguard

You can create HP Serviceguard failover groups with VLANs as long as the primary and standby

links are both VLAN interfaces with the same VLAN ID. See Figure 1-7 for an example. See the

HP Serviceguard documentation for information about using HP-UX VLANs with HP

Serviceguard.
