MIB Object Description Read-Write Supported (Yes/No)
tunnelInetConfigEntry

OID: 1.3.6.1.2.1.10.131.1.1.3.1

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. yes

tunnelInetConfigAddressType

OID: 1.3.6.1.2.1.10.131.1.1.3.1.1

The address type over which the tunnel encapsulates packetsunknown(0),ipv4(1),ipv6(2),ipv4z(3),ipv6z(4),

Yes

(not-accessible)

Only GRE is supported. For possible future support for MPLS, other(1) will be used.

tunnelInetConfigID

OID: 1.3.6.1.2.1.10.131.1.1.3.1. 5

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 is1. 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.

Yes

(not-accessible)

tunnelInetConfigIfIndex

OID: 1.3.6.1.2.1.10.131.1.1.3.1. 6

If the value of tunnelInetConfigStatus 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.

Yes

tunnelInetConfigStatus

OID: 1.3.6.1.2.1.10.131.1.1.3.1. 7

The status of this row, by which new entries may be created, or old entries deleted from this table.

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 tunnelInetConfigID of 1, and set tunnelInetConfigStatus 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 tunnelInetConfigID and set tunnelInetConfigStatus 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.

Yes

Since SET is not supported in this release, only 'active' is supported.

tunnelInetConfigStorageType

OID: 1.3.6.1.2.1.10.131.1.1.3.1. 8

The storage type of this row. If the row is permanent (4), no objects in the row need be writable other(1) volatile (2) nonVolatile (3) permanent(4) readOnly (5)
