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). How-

ever, it is recommended that you use

nwmgr (see nwmgr_vlan (1M) and nwmgr(1M)) for VLAN adminis-

tration on 11i V3 release and forward. Changes made to VLANs interactively with the

lanadmin -V

command are not preserved between system reboots. See WARNINGS .

VLAN lanadmin Command Summary

lanadmin -V create

Create a VLAN.

lanadmin -V modify

Modify a VLAN.

lanadmin -V delete vppa

Delete a VLAN.

lanadmin -V scan

Identify all VLANs and their properties.

lanadmin -V info vppa

Identify a single VLAN and its properties. The command returns 0 on successful completion

and -1 on failure.

lanadmin -V basevppa

Find the minimum acceptable value for a virtual PPA (VPPA).

lanadmin -V help

Display the usage message for the lanadmin -V options.

lanadmin -p ppa

Display the usage information for the interface corresponding to ppa . Test if upper-layer pro-

tocols or applications are running. Use it before deleting VLANs. See lanadmin (1M) for

details.

VLAN lanadmin Options

The

lanadmin command has the following VLAN options:

name name

Specify an optional name for the VLAN. The default is the null string (""). lanadmin

displays this as UNNAMED. name is a string of 0 to 31 alphanumeric characters.

lanadmin_vlan(1M) lanadmin_vlan(1M) (TO BE OBSOLETED) pri priority Specify 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. pri_override level Priority override provides a mechanism to convert IP level precedence (IPV4 ToS octet) to link level 802.1p user priority. Priority override applies to outbound frames only.

lanadmin_vlan(1M) lanadmin_vlan(1M) (TO BE OBSOLETED) To create VLANs, you use nwmgr, ncweb or the lanadmin -V create command. There are multiple required and optional arguments for creating VLANs. If you don’t specify any or all of the optional arguments, the default values described in VLAN lanadmin Options are used. You can either specify a virtual PPA (VPPA) number greater than the minimum allowed VPPA number (5000) or allow the system to assign a VPPA number.

lanadmin_vlan(1M) lanadmin_vlan(1M) (TO BE OBSOLETED) The other properties which are not visible from the snapshot above but are common between the VPPA and the PPA on which it is created are Station Address, Speed and MTU setting. You can verify this by using the lanadmin commands to find out Station Address, Speed and MTU, respectively: lanadmin -a vppa lanadmin -s vppa lanadmin -m vppa Now let’s explore the outputs of lanadmin -V scan and lanscan -p.
