send BFD control packets for a particular session, regardless
of whether it has received any BFD packets for that session.
A system taking the passive role must not begin sending BFD
packets for a particular session until it has received a BFD
packet for that session, and thus has learned the remote system's
discriminator value. |

well-known value for this port. |
| INT hh3cBfdSessOperMode | 1.3.6.1.4.1.25506.2.72.1.3.1.7 | INTEGER | read-only | This variable defines current operating mode that BFD
session is running in.
The primary mode which the BFD session runs in is known as
Asynchronous mode. In this mode, the systems periodically
send BFD Control packets to one another, and if a number of
those packets in a row are not received by the other system,
the session is declared to be down.
The second mode is known as Demand mode. In this mode, it is
assumed that each system has an independent way of verifying
that it has connectivity to the other system. Once a BFD
session is established, the systems stop sending BFD Control
packets, except when either system feels the need to verify
connectivity explicitly, in which case a short sequence of BFD
Control packets is sent, and then the protocol quiesces.
An adjunct to both modes is the Echo function. When the Echo
function is active, a stream of BFD Echo packets is transmitted
in such a way as to have the other system loop them back through
its forwarding path. If a number of packets of the echoed data
stream are not received, the session is declared to be down.
The Echo function may be used with either Asynchronous or
Demand modes.
The 'asynchModeWOEchoFun' indicates this BFD session operates in
the Asynchronous mode, and doesn't support the Echo Function.
The 'demandModeWOEchoFunction' indicates this BFD session operates in
the Demand mode, and doesn't support the Echo Function.
The 'asyncModeWEchoFun' indicates this BFD session operates in
the Asynchronous mode, and also supports the Echo Function.
The 'demandModeWEchoFunction' indicates this BFD session operates in
the Demand mode, and also supports the Echo Function. |
| IPt hh3cBfdSessAddrType | 1.3.6.1.4.1.25506.2.72.1.3.1.8 | InetAddressType | read-only | This object defines IP address type of the interface
associated with this BFD session.
Only values unknown(0), ipv4(1) or ipv6(2)
have to be supported.
A value of unknown(0) is allowed only when
the outgoing interface is of type point-to-point, or
when the BFD session is not associated with a specific
interface.
If any other unsupported values are attempted in a set
operation, the agent must return an inconsistentValue
error. |
| IP hh3cBfdSessLocalAddr | 1.3.6.1.4.1.25506.2.72.1.3.1.9 | InetAddress | read-only | This variable defines IP address of the local interface
from which the BFD packets is transmitted.
It can also be used to enabled BFD on a specific
interface. The value is set to zero when BFD session is not
associated with a specific interface. |
| IP hh3cBfdSessRemoteAddr | 1.3.6.1.4.1.25506.2.72.1.3.1.10 | InetAddress | read-only | This variable defines IP address of the remote interface
from which the BFD packets is transmitted.
It can also be used to enabled BFD on a specific
interface. The value is set to zero when BFD session is not

| BFD hh3cBfdSessLocalDiag | 1.3.6.1.4.1.25506.2.72.1.3.1.11 | BfdDiag | read-only | The BFD diagnostic code for the BFD session was down with the
neighbor. If no such event happens this object contains a zero
value. |
| INT hh3cBfdSessState | 1.3.6.1.4.1.25506.2.72.1.3.1.12 | INTEGER | read-only | The state of the running BFD session.
There are three states through which a session normally
proceeds, two for establishing a session (Init and Up)
and one for tearing down a session (Down.) This allows
a three-way handshake for both session establishment and
session teardown (assuring that both systems are aware of
all session state changes.) A fourth state (AdminDown)
exists so that a session can be administratively put down
indefinitely.
The Down state means that the session is down (or has just been
created.) A session remains in Down state until the remote
system indicates that it agrees that the session is down by
sending a BFD Control packet with the State field set to
anything other than Up. If that packet signals Down state,
the session advances to Init state; if that packet signals
Init state, the session advances to Up state.
Init state means that the remote system is 0communicating,
and the local system desires to bring the session up, but
the remote system does not yet realize it. A session will
remain in Init state until either a BFD Control Packet is
received that is signaling Init or Up state (in which case
the session advances to Up state) or until the detection time
expires, meaning that communication with the remote system
has been lost (in which case the session advances to Down
state.)
Up state means that the BFD session has successfully been
established, and implies that connectivity between the systems
is working. The session will remain in the Up state until either
connectivity fails, or the session is taken down administratively.
If either the remote system signals Down state, or the detection
time expires, the session advances to Down state.
AdminDown state means that the session is being held
administratively down. This causes the remote system to enter
Down state, and remain there until the local system exits
AdminDown state. |
