DESCRIPTION
VLANs are logical, or "virtual," network segments that can span multiple physical network segments. A
primary benefit of VLANs is that they can isolate broadcast and multicast traffic by determining which
destinations should receive that traffic, thereby making better use of switch and end-station resources.
The commands described here are for interactive administration of HP-UX virtual LANs (VLANs).
Changes made to VLANs interactively with the
lanadmin -V command will not be preserved between
system reboots. You must either use the
SAM interface or manually edit the
/etc/rc.config.d/vlanconf
configuration file in order for changes to be preserved across reboots.
lanadmin -V lanadmin options to create, modify, delete, and query VLANs.
lanadmin -p lanadmin option to see if upper-layer protocols or applications are running (used
before deleting VLANs)
lanadmin Options
The lanadmin command options for VLANs are described as follows:
lanadmin -V create vlanid vlanid [pri priority ][tos ToS_value][
vppa vppa ][name name]
[
tos_override level ][pri_override level ]
A VLAN ID, vlanid , uniquely identifies the VLAN to which a frame belongs. The valid range for
vlanid is 0-4094.
The
landamin -V create command options are:
pri priority priority is the 802.1p priority in the tag in the frame header. Switches use the
802.1p priority. The valid range for priority is 0-7. The default is 0.
tos ToS_value ToS is the IP precedence in the IP header. Switches ignore ToS. Routers may
use it. The valid range is 0-255. The default is 0.
vppa vppa A virtual PPA (VPPA) is the PPA associated with a VLAN. They are virtual
because they do not have a unique hardware instance.
name name An optional name for the VLAN. The default value of VLAN name is null string
(""). However, lanadmin displays this as UNNAMED.
tos_override level
ToS override provides a mechanism to override the IP level precedence in the
header of an inbound IP packet. ToS override level strings for inbound traffic
are:
IP_HEADER ToS value in the IP header will be used.
ETHER_HEADER Ether header 802.1p priority will be converted to ToS
value.
CONF_TOS Your specified ToS value will be used.
