DESCRIPTION
"The MIB module for management of IP Tunnels,
independent of the specific encapsulation scheme in
use.
Copyright (C) The Internet Society (2005). This
version of this MIB module is part of RFC 4087; see
the RFC itself for full legal notices."
REVISION "200505160000Z" -- May 16, 2005
DESCRIPTION
"IPv4-specific objects were deprecated, including
tunnelIfLocalAddress, tunnelIfRemoteAddress, the
tunnelConfigTable, and the tunnelMIBBasicGroup.
Added IP version-agnostic objects that should be used
instead, including tunnelIfAddressType,
tunnelIfLocalInetAddress, tunnelIfRemoteInetAddress,
the tunnelInetConfigTable, and the
tunnelIMIBInetGroup.
The new tunnelIfLocalInetAddress and
tunnelIfRemoteInetAddress objects are read-write,
rather than read-only.
Updated DESCRIPTION clauses of existing version-
agnostic objects (e.g., tunnelIfTOS) that contained
IPv4-specific text to cover IPv6 as well.
Added tunnelIfFlowLabel for tunnels over IPv6.
The encapsulation method was previously an INTEGER
type, and is now an IANA-maintained textual
convention.
Published as RFC 4087."

value. It can also be used for row creation. Note
that every row in the tunnelIfTable with a fixed IPv4

SYNTAX Integer32 (1..2147483647)
MAX-ACCESS not-accessible
STATUS deprecated
DESCRIPTION
"An identifier used to distinguish between multiple
tunnels of the same encapsulation method, with the
same endpoints. If the encapsulation protocol only
allows one tunnel per set of endpoint addresses (such
as for GRE or IP-in-IP), the value of this object is
1. For encapsulation methods (such as L2F) which
allow multiple parallel tunnels, the manager is
responsible for choosing any ID which does not
conflict with an existing row, such as choosing a
random number.
Since this object does not support IPv6, it is
deprecated in favor of tunnelInetConfigID."
::= { tunnelConfigEntry 4 }
tunnelConfigIfIndex OBJECT-TYPE
SYNTAX InterfaceIndexOrZero
MAX-ACCESS read-only
STATUS deprecated
DESCRIPTION
"If the value of tunnelConfigStatus for this row is
active, then this object contains the value of ifIndex
corresponding to the tunnel interface. A value of 0
is not legal in the active state, and means that the
interface index has not yet been assigned.
Since this object does not support IPv6, it is
deprecated in favor of tunnelInetConfigIfIndex."
::= { tunnelConfigEntry 5 }
tunnelConfigStatus OBJECT-TYPE
SYNTAX RowStatus
MAX-ACCESS read-create
STATUS deprecated
DESCRIPTION
"The status of this row, by which new entries may be
created, or old entries deleted from this table. The
agent need not support setting this object to
createAndWait or notInService since there are no other
writable objects in this table, and writable objects
in rows of corresponding tables such as the
tunnelIfTable may be modified while this row is
active.
To create a row in this table for an encapsulation
method which does not support multiple parallel
tunnels with the same endpoints, the management
station should simply use a tunnelConfigID of 1, and
set tunnelConfigStatus to createAndGo. For
encapsulation methods such as L2F which allow multiple
parallel tunnels, the management station may select a
pseudo-random number to use as the tunnelConfigID and
set tunnelConfigStatus to createAndGo. In the event
that this ID is already in use and an
inconsistentValue is returned in response to the set
operation, the management station should simply select
a new pseudo-random number and retry the operation.
Creating a row in this table will cause an interface
index to be assigned by the agent in an
implementation-dependent manner, and corresponding
rows will be instantiated in the ifTable and the
tunnelIfTable. The status of this row will become
active as soon as the agent assigns the interface
index, regardless of whether the interface is
operationally up.
Deleting a row in this table will likewise delete the
corresponding row in the ifTable and in the
tunnelIfTable.
Since this object does not support IPv6, it is
deprecated in favor of tunnelInetConfigStatus."

tunnelInetConfigTable OBJECT-TYPE
SYNTAX SEQUENCE OF TunnelInetConfigEntry
MAX-ACCESS not-accessible

DESCRIPTION
"The (conceptual) table containing information on
configured tunnels. This table can be used to map a
set of tunnel endpoints to the associated ifIndex
value. It can also be used for row creation. Note
that every row in the tunnelIfTable with a fixed
destination address should have a corresponding row in
the tunnelInetConfigTable, regardless of whether it
was created via SNMP."
::= { tunnel 3 }
tunnelInetConfigEntry OBJECT-TYPE
SYNTAX TunnelInetConfigEntry
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION
"An entry (conceptual row) containing the information
on a particular configured tunnel. Note that there is
a 128 subid maximum for object OIDs. Implementers
need to be aware that if the total number of octets in
tunnelInetConfigLocalAddress and
tunnelInetConfigRemoteAddress exceeds 110 then OIDs of
column instances in this table will have more than 128
sub-identifiers and cannot be accessed using SNMPv1,
SNMPv2c, or SNMPv3. In practice this is not expected
to be a problem since IPv4 and IPv6 addresses will not
cause the limit to be reached, but if other types are
supported by an agent, care must be taken to ensure
that the sum of the lengths do not cause the limit to
be exceeded."
