NAME
vdptool - manage the VSI associations and status of lldpad
SYNOPSIS
vdptool <command> [options] [argument]
DESCRIPTION
vdptool is used to query and configure the VSI associations in lldpad. Only the ratified stardard
version of the VDP protocol (also referred to as vdp22) is supported. It connects to the client
interface of lldpad to perform these operations. vdptool will operate in interactive mode if it is
executed without a command. In interactive mode, vdptool will also function as an event listener to
print out events as they are received asynchronously from lldpad(still to be done). It will use
libreadline for interactive input when available (still to be done).
OPTIONS
-i [ifname]
specifies the network interface to which the command applies. Most vdptool commands require
specifying a network interface.
-V [tlvid]
specifies the VDP tlv identifier to be set or queried.
The tlvid is an integer value used to identify specific VDP TLVs. The tlvid value is the type
value for types not equal to 127 (the organizationally specific type). For organizationally
specific TLVs, the tlvid is the value represented by the 3 byte OUI and 1 byte subtype - where the
subtype is the lowest order byte of the tlvid.
The tlvid can be entered as a numerical value (e.g. 10 or 0xa), or for supported TLVs, as a
keyword (such as assoc, deassoc, preassoc, preassoc-rr, etc). Review the vdptool help output to
see the list of supported TLV keywords.
Use option -c to specify the parameters and its values to be set or queried.
-n "neighbor" option for commands which can use it (e.g. get-tlv). Use this flag to retrieve the
last VDP22 data returned from the bridge. (not yet supported).
-c <argument list>
Specifies additional parameters for TLV queries and associations commands. The argument list
varies, depending on the command option (-T) or (-t). To establish a VSI association use the
command option (-T) and specify additional information as arguments in the form of key=value. See
the VSI Parameter subsection and Example section below. To query a VSI specific association use
the command option (-t) and specify the value of the VSI Instance Identifier (keyword uuid
followed be the VSI UUID value) of the VSI association as configuration parameter.
-r show raw client interface messages
-R show only raw Client interface messages
-W Wait for the bridge response message
VSI Parameter
Each VDP22 TLVs contains a command mode, manager identifier, type identifier, type identifier version,
VSI instance identifier, migration hints and filter information. The fields are explained next:
mode (Command Mode):
The command mode determines the type of the VSI association to be established. It is an ascii
string can be one of:
assoc: Create an VSI association.
preassoc:
Create an VSI preassociation. The association is only announced to the switch.
preassoc-rr:
Create an VSI preassociation. The association is only announced to the switch and the
switch should reserve the resources.
deassoc:
Delete an VSI association.
Other strings are not recognized and return an error.
mgrid2 (Manager identifier):
The manager identifier is a string of up to 16 alphanumeric characters. It can also be an UUID
according to RFC 4122 with optional dashes in between.
typeid (Type Identifier):
The type identifier is a number in the range of 0 to 2^24 - 1.
typeidver (Type Identifier Version):
The type identifier version is a number in the range of 0 to 255.
uuid (VSI Instance Identifier):
The VSI instance identifier is an UUID according to RFC 4122 with optional dashes in between.
hints (Migration Hints):
The migration hints is a string aiding in migration of virtual machines:
none: No hints available.
from: The virtual machine is migrating away.
to: The virtual machine is migrating to.
fid (Filter Information Data):
The filter information data can be supplied in four different formats identified by numbers in
parathesis. Multiple filter information fields can be supplied, but all have to be of the same
format.
vlan (1)
A vlan number only, also known as filter information format 1. The vlan identifier is a
number in the range of 1 to 2^16 - 1. The high order 4 bits are used as quality of service
bits. The vlan identifier can be zero, a vlan identifier is then selected by the switch.
Refer to IEEE 802.1 Qbg ratified standard for details.
vlan-mac (2)
A vlan number and MAC address delimited by a slash ('-'), also known as filter information
format 2. The MAC address is specified in the format xx:xx:xx:xx:xx:xx. The colons are
mandatory. For vlan details see (1).
vlan-mac-group (4)
A vlan number, MAC address and group identifier, each delimited by a slash ('-'), also
known as filter information format 4. The group identifier is a 32 bit number. For vlan
and MAC address details see (1) and (2).
vlan--group (3)
A vlan number and group identifier, delimited by two slashes ('--'), also known as filter
information format 3. For vlan and group details see (1) and (4).
oui (Organizationally Unique Identifier):
This defines the optional Organizationally defined information field. This contains the specific
sets of values for this entry. There can be multiple organizational specific fields, in which case
there will be multiple keywords oui= followed by the values. The value is of the following
format:
oui=OUI,[Organization specific values ]
The OUI specifies the name of the Organization that is responsible for defining this content. A
comma is mandatory after the OUI field. The fields following this
is specified by the organization and hence will be decoded based on the value of this OUI field.
Currently, the following values for OUI are supported.
cisco Specifies Cisco defined OUI.

NOTES
This tool is in its early design and development phase. It it buggy, incomplete and most of the ideas
have not even been thought of.... It reflects the current state of development when I had been given
another work assignment. I append it so some else can continue to work on this.
EXAMPLES
