--
-- Interpretation of the Interface Table for VLANs and encapsulation
-- interfaces:
--
-- OBJECT VALUE/USE
--
-- ifIndex Same interpretation as RFC1573. A unique value,
-- greater than zero for each VLAN interface.
--
-- ifDescr Same interpretation as RFC1573. A textual string
-- containing information anout the interface. This
-- string should include the name of the manufacturer,
-- the product name, the version of the software, and that
-- the interface is a vlan. Example: "3COM LANPlex 2500,
-- version 8.1, VLAN"
--
-- ifType propVirtual(53)
--
-- ifMtu Equivalent to the least common denominator MTU of the
-- set of ports in the VLAN. For example, if the VLAN
-- contains one ethernet port, then the value of this
-- object is 1518. If the VLAN contains all FDDI ports,
-- the value of this object is 4500. If a vlan contains
-- a mix of ethernet and FDDI ports, the value of this
-- object is 1518.
--
-- ifSpeed The value of this object is zero, as defined by RFC1573
-- for sub-layers that have no concept of bandwidth.
--
-- ifPhysAddress The value of this object is always equal to a null octet
-- string.
--
-- ifAdminStatus Always equal to up(1). SetRequest-PDUs fail.
--
-- ifOperStatus The value of this object is equal to up(1) if the
-- ifOperStatus of at least one port in in the set of ports
-- stacked below the VLAN layer is up(1). The value of this
-- object is down(2) if the ifOperStatus of all ports stacked
-- below the vlan layer is down(2). The value of this
-- object is down(2) if there are no ports stacked below the
-- the vlan sublayer.
--
-- ifLastChange Same interpretation as RFC1573. The value of sysUpTime
-- at the time the interface entered its current operational
-- state. If the current state was entered prior to the
-- last re-initialization of the local network management
-- subsystem, then this object contains a zero value.
--
-- ifInOctets These objects return NO_SUCH_NAME on reads and writes.
-- ifInUcastPkts This approach is more desireable than returning zero
-- ifInNUcastPkts on reads because NMS's cannot differentiate between
-- ifInDiscards returning a zero for non-support vs returning a real
-- ifInErrors zero value for the counter. Inability to distinguish
-- ifInUnknownProtos between these two cases would essentially prevent
-- ifOutOctets future implementation of these objects, therefore NO_SUCH_NAME
-- ifOutUcastPkts is returned to indicate no-support. Future implementations
-- ifOutNUcastPkts may choose to return real values for these counters.
-- ifOutDiscards "
-- ifOutErrors "
-- ifLinkUpDownTrapEnable "
-- ifConnectorPresent "
-- ifHighSpeed "
-- ifName "
--
-- ifOutQLen Deprecated in RFC1573. Set to zero if present.
-- ifSpecific Deprecated in RFC1573. Set to { 0.0 } if present.
--
-- linkUp TRAP Not supported for the vlan sublayer
-- linkDown TRAP Not supported for the vlan sublayer

-- 3COM Vlan Type Textual Convention
--
-- vlanLayer2(1) = The globally identified VLAN interface is protocol
-- independent and based on port grouping. The configuration of
-- port grouping is controlled through the ifStackTable.
--
-- vlanUnspecifiedProtocols(2) = The globally identified VLAN interface is
-- known as Explicit Unspecified Protocols. The forwarding behavior
-- of this type of VLAN interface is defined as follows:
--
-- On devices that support layer 3 VLAN interfaces, there is an
-- Implicit Unspecified Protocols VLAN interface defined (See
-- diagram 1 below). The flooding behavior of the Implicit
-- Unspecified Protocols VLAN interface is to forward all
-- broadcast/multicast/unknown DA frames to all non-source
-- ports.

-- +===+===+===+===+===+===+===+===+
-- ^
-- |
-- Any protocol frame sourced on port 1 is flooded to ports 2-8
--
-- To change the above flooding behavior, an NMS can configure
-- an Explicit Unspecified Protocols for a single port or
-- a group of ports by using vlanUnspecifiedProtocols(2) (See
-- Diagram 2).

-- A row must be created in this table for each IP
-- VLAN interface that shares 1 or more ports with
-- with another IP VLAN interface. Entries in this

-- in the a3ComVlanIfTable. The NMS must remove entries
-- in this table, prior to removing the corresponding entry
-- in the a3ComVlanIfTable.
--
-- The information in this table is used to convey additional

The following values may be read:
active(1)
notInService(2)
notReady(3).
Setting this object to createAndGo(4) causes the agent
to attempt to create and commit the row based on
the contents of the objects in the row. If all necessary
information is present in the row and the values are
acceptible to the agent, the agent will change the
status to active(1). If any of the necessary objects
are not available, the agent will reject the creation
request.
Setting this object to createAndWait(5) causes a row
in this table to be created. The agent sets the
status to notInService(2) if all of the information is
present in the row and the values are acceptable to the
agent; otherwise, the agent sets the status to
notReady(3).
Setting this object to active(1) is only valid when
the current status is active(1) or notInService(2).
Row creation to this table is only possible when a
corresponding VLAN entry has been created in the
a3ComVlanTable with an a3ComVlanType set to
vlanLayeredProtocols(16).
Setting this object to destroy(6) will remove the
corresponding VLAN interface to protocol mapping."

-- The 3Com VLAN Encapsulation Interface Table
--
-- VLAN Encapsulation refers to the ability to multiplex
-- several VLANs over a single network segment by explicitly
-- labeling eack packet with a tag that identifies the packet's
-- VLAN membership.
--
-- There exist at least 2 tagging algorithms: a 3Com proprietary tagging
-- scheme developped by PDD ("VLT tagging"), a standard tagging scheme
-- under development in IEEE ("802.1q tagging"). Within a given device
-- (i.e., within a givin agents purview), both tagging schemes may be
-- in use simultaneously, possibly for different segments associated
-- with the same VLAN. Even when only a single tagging scheme is in use, a
-- a single VLAN may be represented with different tags when traffic is
-- transmitted/received through different (tagging) ports. Some ports
-- support tagging, some don't. For ports that support tagging, they may
-- sometimes operate in tagging mode, sometime not in tagging mode.
-- (Conceivably, one could also have ports that handle a mixture of tagged
-- and untagged traffic.)
--
-- The encapsulation interface will be creatable by the NMS using a table
-- similar to the a3ComVlanIfTable. This table will allow the NMS to define
-- certain attributes of the encapsulation including an encapsulation
-- algorithm and a tag value. Using the ifStack table, an encapsulation
-- interface may be stacked underneath a VLAN interface and on top of port(s).
--
-- Example ifTable Stacking:
--
-- +=======================+=======================+
-- | VLAN Xface 9 | VLAN Xface 11 |
-- +=======================+=======================+
-- +=======================+
-- | ENCAPS Xface 10 |
-- +=======================+
-- +=====+=====+=====+=====+=====+=====+=====+=====+
-- | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 |<=== Ports

--
-- A stack that contains a VLAN, encapsulation and a port interface, specifies:
--
-- * For packets received through the given port that use the given encapsulation
-- scheme and contain the given tag, those packets are members of the given VLAN.
--
-- * For unencapsulated packets from the given VLAN that are to be transmitted out
-- the given port, those packets must first be encapsulated using the given
-- encapsulation algorithm and tag.
--
-- This table is implemented by all 3Com network devices that
-- support the encapsulation of multiple VLANs over a single interface.

"The row status for this VLAN encapsulation interface.
This OBJECT can be set to:
active(1)

createAndWait(5)
destroy(6)
The following values may be read:
active(1)
notReady(3).
In order for a row to become active, the NMS must set
a3ComVlanEncapsIfTagType and a3ComVlanEncapsIfTag to
some valid and consistent values.
Setting this object to createAndGo(4) causes the agent
to attempt to create and commit the row based on the
contents of the objects in the row. If all necessary
information is present in the row, the agent will
create the row and change the status to active(1). If
any of the necessary objects are not available, or
specify an invalid configuration, the row will not be
created and the agent will return an appropriate error.
Setting this object to createAndWait(5) causes a row in
in this table to be created. If all necessary objects
in the row have been assigned values and specify a valid
configuration, the status of the row will be set to
notInService(2); otherwise, the status will be set to
notReady(3).
This object may only be set to createAndGo(4) or
createAndWait(5) if it does not exist.
Setting this object to active(1) when the status is
notInService(2) causes the agent to commit the
row. Setting this object to active(1) when its value
is already active(1) is a no-op.
Setting this object to destroy(6) will remove the
corresponding VLAN encapsulation interface, remote the
entry in this table, and remove the corresponding entry
in the ifTable.
In order for a set of this object to destroy(6) to
succeed, all dependencies on this row must have been
removed. These will include any references to this
interface in the ifStackTable."

DESCRIPTION
"The value of the next available virtual ifIndex. This
object is used by an NMS to select an index value
for row-creation in tables indexed by ifIndex. The
current value of this object is changed to a new
value when the current value is written to an agent's
table, that is indexed by ifIndex. Row creation
using the current value of this object, allocates
a virtual ifIndex. Note the following:
1. A newly created row does not have to be active(1)
for the agent to allocate the virtual ifIndex.
2. Race conditions between multiple NMS's end when
a row is created. Rows are deemed created when
a setRequest is successfully committed (i.e.
the errorStats is noError(0)).
3. An agent that exhausts its supply of virual
ifIndex values returns zero as the value of this
object. This can be used by an NMS as an indication
to deleted unused rows and reboot the device."
