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."

A value of -1 indicates that the bits are copied from the payload's header. A value of -2 indicates that a traffic conditioner is invoked and more information may be available in a traffic conditioner MIB module. A value between 0 and 63 inclusive indicates that the bit field is set to the indicated value.

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." ::= { tunnelConfigEntry 6 } tunnelInetConfigTable OBJECT-TYPE SYNTAX SEQUENCE OF TunnelInetConfigEntry MAX-ACCESS not-accessible STATUS current DESCRIPTION "The (conceptual) table containing information on configured tunnels.

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."
