CIENA-CES-LDP-MIB
The CIENA-CES-LDP-MIB extends standard LDP MIB definitions to monitor Label Distribution Protocol session states, label bindings, and LDP neighbor adjacencies on Ciena Carrier Ethernet Services (CES) platforms. This module enables granular visibility into LDP signaling mechanisms and session health specifically for Ciena hardware implementations.

cienaCesLdpHelloHoldTimeThe 16-bit integer value which is the proposed
global hello hold timer (in seconds) for LDP.
An LSR maintains a record of Hellos received
from potential peers. This object represents
the Hold Time in the Common Hello Parameters TLV of
the Hello Message.
A value of 65535 means infinite (i.e., wait forever).
All other values represent the amount of time in
seconds to wait for a Hello Message. Setting the
hold time to a value smaller than 15 is not
recommended, although not forbidden according
to RFC3036.ro Unsigned32 .1.3.6.1.4.1.1271.2.1.17.1.1.3 |

cienaCesLdpGRModeLDP Graceful restart Operational status.ro Enumeration .1.3.6.1.4.1.1271.2.1.17.1.1.6 |
cienaCesLdpReconnectTimeThe period of time that the local node takes to
restart LDP and bring up the LDP sessions.This is
advertised to neighbors in the FT Session TLV
in Initialization messages.
The value chosen should be large enough for LDP to be
terminated and restarted.
For devices which only act as the Helper node, this timer
is unused and will return value 0.ro Unsigned32 .1.3.6.1.4.1.1271.2.1.17.1.1.7 |
cienaCesLdpRecoveryTimeThe period of time that the local node is willing to
retain its MPLS forwarding state, if any,that it
preserved across the restart.
This field is used to calculate the Recovery Time for both
Control Plane and Control Channel restarts. It is used to
calculate the Recovery Time advertised in the FT Session
TLV in the Initialization message sent to the neighbor.
For devices which only act as the Helper node, this timer
is unused and will return value 0.ro Unsigned32 .1.3.6.1.4.1.1271.2.1.17.1.1.8 |
cienaCesLdpMaxPeerReconnectThe maximum period of time that LDP should wait for a
restart capable neighbor to restore an LDP session.
LDP waits for the minimum of this time and the Reconnect
Timeout advertised in the FT Session TLV in the
Initialization message from the neighbor.ro Unsigned32 .1.3.6.1.4.1.1271.2.1.17.1.1.9 |
cienaCesLdpMaxPeerRecoveryThe maximum period of time that LDP should wait for a
restart capable neighbor to refresh Label Mappings
previously received from that neighbor before deleting
the stale bindings.
LDP waits for the minimum of this time and the Recovery
Time advertised in the FT Session TLV in the
Initialization message from the neighbor.
This value is not used to set the Recovery Time advertised
in the FT Session TLV in the Initialization message sent
to the neighbor.ro Unsigned32 .1.3.6.1.4.1.1271.2.1.17.1.1.10 |
cienaCesLdp OBJECT IDENTIFIER .1.3.6.1.4.1.1271.2.1.17.1.2 |
cienaCesLdpSessionTableA table of Sessions between the LDP Entities
and LDP Peers. Each row in this table
represents a single session. SEQUENCE OF CienaCesLdpSessionEntry .1.3.6.1.4.1.1271.2.1.17.1.2.1 |
cienaCesLdpSessionEntryAn entry in this table represents information on a
single session between an LDP Entity and LDP Peer.
The information contained in a row is read-only.
Note: The Path Vector Limit for the
Session is the value that is configured in
the corresponding mplsLdpEntityEntry. The
Peer's Path Vector Limit is in the
mplsLdpPeerPathVectorLimit object in the
mplsLdpPeerTable.
Values that may differ from those configured are
noted in the objects of this table, the
mplsLdpAtmSessionTable and the
mplsLdpFrameRelaySessionTable. A value
differs if it was negotiated between the
Entity and the Peer. Values may or may not
be negotiated. For example, if the values
are the same then no negotiation takes place.
If they are negotiated, then they may differ. CienaCesLdpSessionEntry .1.3.6.1.4.1.1271.2.1.17.1.2.1.1 |
cienaCesLdpEntityLdpIdThe LDP identifier. The first four octets encode an IP
address assigned to the LSR, and the last two octets
identify a specific label space within the LSR. MplsLdpIdentifier (MPLS-TC-STD-MIB) .1.3.6.1.4.1.1271.2.1.17.1.2.1.1.1 |
cienaCesLdpEntityIndexThis index is used as a secondary index to uniquely
identify this row.
A secondary index (this object) is meaningful to some
but not all, LDP implementations. For example,
an LDP implementation that uses PPP would
use this index to differentiate PPP sub-links.
Another way to use this index is to assign it the
value of ifIndex. Unsigned32 .1.3.6.1.4.1.1271.2.1.17.1.2.1.1.2 |
cienaCesLdpPeerLdpIdThe LDP identifier of this LDP Peer. MplsLdpIdentifier (MPLS-TC-STD-MIB) .1.3.6.1.4.1.1271.2.1.17.1.2.1.1.3 |
cienaCesLdpSessionConfiguredHoldTimeThe locally configured keepalive hold time for this
session, in seconds. Note that the value of this field
reflects configuration at the time of session
initialization; this may differ from the configuration
that would apply to a new session, if configuration has
changed since this session was initialized.ro Unsigned32 .1.3.6.1.4.1.1271.2.1.17.1.2.1.1.4 |
cienaCesLdpSessionPeerHoldTimeThe peer's advertised keepalive hold time for this session
in seconds. Note that the value of this field reflects
the peer's configuration at the time of session
initialization; this may differ from the configuration
that would apply to a new session, if the peer's
configuration has changed since this session was
initialized.ro Unsigned32 .1.3.6.1.4.1.1271.2.1.17.1.2.1.1.5 |
cienaCesLdpSessionHoldTimeInUseThe keepalive hold time that is currently in use for this
session, in seconds.ro Unsigned32 .1.3.6.1.4.1.1271.2.1.17.1.2.1.1.6 |

cienaCesLdpHelloAdjacencyEntryEach row represents a single LDP Hello Adjacency.
An LDP Session can have one or more Hello
Adjacencies. CienaCesLdpHelloAdjacencyEntry .1.3.6.1.4.1.1271.2.1.17.1.2.2.1 |
cienaCesLdpHelloAdjacencyIndexAn identifier for this specific adjacency. Unsigned32 .1.3.6.1.4.1.1271.2.1.17.1.2.2.1.1 |
