- MAX-ACCESS read-only
- STATUS current
- DESCRIPTION
- "The encapsulation method used by the tunnel. The value
- direct indicates that the packet is encapsulated directly
- within a normal IPv4 header, with no intermediate header,
- and unicast to the remote tunnel endpoint (e.g., an RFC 2003
- IP-in-IP tunnel, or an RFC 1933 IPv6-in-IPv4 tunnel). The
- value minimal indicates that a Minimal Forwarding Header
- (RFC 2004) is inserted between the outer header and the
- payload packet. The value UDP indicates that the payload
- packet is encapsulated within a normal UDP packet (e.g., RFC
- 1234). The remaining protocol-specific values indicate that
- a header of the protocol of that name is inserted between
- the outer header and the payload header."

- tunnelIfHopLimit OBJECT-TYPE
- SYNTAX Integer32 (0..255)
- MAX-ACCESS read-write

- DESCRIPTION
- "The method used by the tunnel to secure the outer IP
- header. The value ipsec indicates that IPsec is used
- between the tunnel endpoints for authentication or
- encryption or both. More specific security-related
- information may be available in a MIB for the security
- protocol in use."
- ::= { tunnelIfEntry 5 }

- SYNTAX Integer32 (-2..63)
- MAX-ACCESS read-write
- STATUS current
- DESCRIPTION
- "The method used to set the high 6 bits of the TOS in the
- outer IP header. 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. A value
- between 0 and 63 inclusive indicates that the bit field is
- set to the indicated value."
- ::= { tunnelIfEntry 6 }
- tunnelConfigTable OBJECT-TYPE
- SYNTAX SEQUENCE OF TunnelConfigEntry
- MAX-ACCESS not-accessible
- STATUS current
- 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 tunnelConfigTable, regardless of
- whether it was created via SNMP."
- ::= { tunnel 2 }

- tunnelConfigLocalAddress OBJECT-TYPE
- SYNTAX IpAddress
- MAX-ACCESS not-accessible

- DESCRIPTION
- "The address of the local endpoint of the tunnel, or 0.0.0.0
- if the device is free to choose any of its addresses at
- tunnel establishment time."

- ::= { tunnelConfigEntry 3 }
- tunnelConfigID OBJECT-TYPE
- SYNTAX Integer32 (1..2147483647)
- MAX-ACCESS not-accessible
- STATUS current
- 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."
- ::= { tunnelConfigEntry 4 }
- tunnelConfigIfIndex OBJECT-TYPE
- SYNTAX InterfaceIndexOrZero
- MAX-ACCESS read-only
- STATUS current
- 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."
- ::= { tunnelConfigEntry 5 }
- tunnelConfigStatus OBJECT-TYPE
- SYNTAX RowStatus
- MAX-ACCESS read-create
- STATUS current
- 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."
