For a detailed overview of the documents that describe the current Internet-Standard Management Framework, check out section 7 of RFC 3410 [RFC3410] 📚
Managed objects are accessed through a virtual information store called the Management Information Base, or MIB 🗄️ MIB objects are generally accessed through the Simple Network Management Protocol (SNMP) 🛰️ Objects in the MIB are defined using the mechanisms in the Structure of Management Information (SMI) 🧩 This memo specifies a MIB module that is compliant to the SMIv2, which is described in STD 58, RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580 [RFC2580] 💅
2. Introduction 🌈
Right now the IETF is working on a suite of protocols that will act as a common control plane and a separate common measurement plane 🔥 Generalized MPLS (GMPLS) [RFC3471] and the Link Management Protocol [RFC4204] are the key pieces of this standardization effort ✨ The main job of LMP is to manage traffic engineering (TE) links 🛣️ Its primary goals are maintaining control channel connectivity, correlating link properties, verifying data-bearing links, and detecting and isolating link faults 🫶
In this document we describe a MIB module you can use to manage LMP implementations 🎀 It covers both the configuration and the performance-monitoring sides of LMP 📊
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119 [RFC2119] 🙈
3. Terminology 📖
This document uses terminology from the document describing the Link Management Protocol [RFC4204] 🧾 An "LMP adjacency" forms between two nodes that support the same capabilities, and LMP messages get exchanged between the node pair over the control channels that make up this adjacency 🤝 Several control channels can be active at the same time 🦋 Except for messages related to control channel management, whenever an LMP message needs to go to a neighbor node, it can be sent on any of the active control channels 🌸 The control channels can also carry MPLS control plane information or routing information 🧚
LMP is designed to aggregate one or more data-bearing links into a traffic-engineering (TE) link 💜 The data-bearing links can be either component links or ports, depending on their multiplexing capability (see [RFC4204] for the distinction between port and component link) 🍓
Each TE link is associated with an LMP adjacency, and one or more control channels are used to exchange LMP messages for a particular adjacency 👑 In turn, control channels are used to manage the TE links associated with the LMP adjacency 💖
4. Feature Checklist ✅
The Link Management Protocol MIB module (LMP-MIB) is designed to satisfy the following requirements and constraints 💅
- The MIB module supports enabling and disabling LMP capability on LMP-capable interfaces of a photonic switch, optical cross-connect, or router 🔦
- The MIB module is used to provide information about LMP adjacencies 🤝
- Support is provided for configuring the keep-alive and link verification parameters ⏰
- The MIB module is used to express the mapping between local and remote TE links, as well as local and remote interface identifiers for port or component link 🗺️
- Performance counters are provided for measuring LMP performance on a per-control channel basis. Performance counters are also provided for measuring LMP performance on the data-bearing links 📈
Heads up, the LMP MIB module goes hand-in-hand with the TE Link (TE-LINK-STD-MIB) MIB module [RFC4220] 🫶 The TE link table, which is used to associate data-bearing links to TE links, is defined in the TE Link MIB. The TE link table in the LMP MIB module contains TE link information specific to LMP 🎀
5. Outline 🗺️
Configuring LMP through an optical device involves the following steps 🌟
- Enabling LMP on LMP-capable interfaces through control channel configuration.
- Optionally, specifying link verification parameters.
- Configuring the data-bearing links and associating them to the appropriate TE link (this association is stored in the
ifStackTableof the Interfaces Group MIB).
TE links are managed by the control channels that run between the same pair of nodes (LMP adjacency) 💜
6. Brief Description of MIB Objects 🧁
Sections 6.1 - 6.8 describe objects pertaining to LMP 🦋 The MIB objects were derived from the LMP document [RFC4204] ✨
6.1. lmpNbrTable 🤝
The remote node table identifies the pair of nodes that exchange LMP messages over control channels 💌
6.2. lmpControlChannelTable 🔌
The control channel table is used for enabling the LMP protocol on LMP-capable interfaces 🔛 A photonic switch, optical cross-connect, or router creates an entry in this table for every LMP-capable interface in that device 🖥️
6.3. lmpControlChannelPerfTable 📊
The control channel performance table collects LMP performance counts on a per-control channel basis 📈 Each entry in the lmpControlChannelTable has a corresponding entry in the lmpControlChannelPerfTable 🫶
6.4. lmpTeLinkTable 🛣️

6.5. lmpLinkVerificationTable 🔍
The link verification table is used for configuring the LMP link verification parameters of TE links 🧐 For every TE link entry in the lmpTeLinkTable that supports the link verification procedure, there is a corresponding entry in the lmpLinkVerificationTable 💅
6.6. lmpTeLinkPerfTable 📉
The TE link performance table collects LMP performance counts on a per-TE link basis 🔥 Each entry in the lmpTeLinkTable has a corresponding entry in the lmpTeLinkPerfTable 🌈
6.7. lmpDataLinkTable 🧵

6.8. lmpDataLinkPerfTable 📈
The data-bearing link performance table collects LMP performance counts on data-bearing links 👑
7. Example of LMP Control Channel Setup ✨
okay so this section is a little walkthrough of how you'd use the MIB objects from Section 9 to set up an LMP control channel 🦋 it's not trying to show every single nuance of the MIB module, just the key concepts, so read it AFTER you've gone through the MIB itself 💅
Let's say you want an LMP adjacency between two nodes, using two control channels 🫶 there are also three data-bearing links, and we're assuming those data-bearing links are ports (lambdas) and that link verification is not turned on 🌈 the example below shows which rows and objects you'd create to make it happen 🎀
First, LMP needs to be enabled between the pair of nodes 🍓
In lmpNbrTable:
{
lmpNbrNodeId = 'c0000201'H, -- 192.0.2.1
lmpNbrAdminStatus = up(1),
lmpNbrRowStatus = createAndGo(4),
lmpNbrStorageType = nonVolatile(3)
}Then it's time for the control channels, which get created in the lmpControlChannelTable ✨
In lmpControlChannelTable:
{
lmpCcId = 1,
lmpCcUnderlyingIfIndex = 1,
lmpCcIsIf = false(2),
lmpCcAuthentication = false(2),
lmpCcHelloInterval = 15,
lmpCcHelloIntervalMin = 15,
lmpCcHelloIntervalMax = 1000,
lmpCcHelloDeadInterval = 45,
lmpCcHelloDeadIntervalMin = 45,
lmpCcHelloDeadIntervalMax = 1000,
lmpCcAdminStatus = up(1),
lmpCcRowStatus = createAndGo(4),
lmpCcStorageType = nonVolatile(3)
}
{
lmpCcId = 2,
lmpCcUnderlyingIfIndex = 2,
lmpCcIsIf = false(2),
lmpCcAuthentication = false(2),
lmpCcHelloInterval = 15,
lmpCcHelloIntervalMin = 15,
lmpCcHelloIntervalMax = 1000,
lmpCcHelloDeadInterval = 45,
lmpCcHelloDeadIntervalMin = 45,
lmpCcHelloDeadIntervalMax = 1000,
lmpCcAdminStatus = up(1),
lmpCcRowStatus = createAndGo(4),
lmpCcStorageType = nonVolatile(3)
}Next up are the three data-bearing links 🧚 each one needs an ifEntry with the same ifIndex created beforehand, so make sure those exist first!
In lmpDataLinkTable:
{
ifIndex = 41,
lmpDataLinkAddressType = unknown(0),
lmpDataLinkIpAddr = ''H,
lmpDataLinkRemoteIpAddress = ''H,
lmpDataLinkRemoteIfId = 47,
lmpDataLinkRowStatus = createAndGo(4),
lmpDataLinkStorageType = nonVolatile(3)
}
{
ifIndex = 43,
lmpDataLinkAddressType = unknown(0),
lmpDataLinkIpAddr = ''H,
lmpDataLinkRemoteIpAddress = ''H,
lmpDataLinkRemoteIfId = 42,
lmpDataLinkRowStatus = createAndGo(4),
lmpDataLinkStorageType = nonVolatile(3)
}
{
ifIndex = 44,
lmpDataLinkAddressType = unknown(0),
lmpDataLinkIpAddr = ''H,
lmpDataLinkRemoteIpAddress = ''H,
lmpDataLinkRemoteIfId = 48,
lmpDataLinkRowStatus = createAndGo(4),
lmpDataLinkStorageType = nonVolatile(3)
}Quick heads-up 👑 you don't have to provision the data-bearing link type (lmpDataLinkType), because the node fills it in automatically. The protection role for those data-bearing links (primary or secondary) lives in the componentLinkTable of the TE Link MIB module [RFC4220] 💜
Then a TE link gets created as an ifEntry with ifType teLink in the ifTable 🌸 once that's in place, you add a TE link entry to the LMP MIB module, which holds the LMP-specific TE link info ✨
In lmpTeLinkTable:
{
ifIndex = 20,
lmpTeLinkVerification = true(1),
lmpTeLinkFaultManagement = true(1),
lmpTeLinkDwdm = false(2),
lmpTeLinkRowStatus = createAndGo(4),
lmpTeLinkStorageType = nonVolatile(3)
}and in lmpLinkVerificationTable:
{
ifIndex = 20,
lmpLinkVerifyInterval = 100,
lmpLinkVerifyDeadInterval = 300,
lmpLinkVerifyTransportMechanism = j0Trace(3),
lmpLinkVerifyAllLinks = true(1),
lmpLinkVerifyTransmissionRate = 100000,
lmpLinkVerifyWavelength = 0,
lmpLinkVerifyRowStatus = createAndGo(4),
lmpLinkVerifyStorageType = nonVolatile(3)
}The link between the data-bearing links and the TE links is stored in the ifStackTable [RFC2863] 🔥
And in parallel with the entry you made in the lmpTeLinkTable, you may also create an entry in the teLinkTable of the TE Link MIB module [RFC4220] 🦋
8. Application of the Interfaces Group to LMP
The Interfaces Group [RFC2863] is where the generic managed objects for interfaces live 💖 this memo adds the media-specific extensions for managing LMP control channels that are modeled as interfaces 🎀 if the control channel from the lmpControlChannelTable is modeled as an ifEntry, the following definition applies. An lmpControlChannelTable entry counts as represented by an Interfaces MIB ifEntry when its lmpControlChannelEntry object lmpCcIsIf is set to true (1). In that case the control channel SHOULD be modeled as an ifEntry and get proper interface stacking, as described below 🫶
This memo reads the Interfaces Group the way [RFC2863] does 🧠 that RFC says the interfaces table (ifTable) holds info about the managed resource's interfaces, and that every sub-layer below the internetwork layer of a network interface counts as an interface. Since an LMP interface only carries control traffic, it sits below the internetwork layer, so it can show up as an entry in the ifTable 💅 how the ifTable entries relate to each other is defined by the Interfaces Stack Group in [RFC2863] 👑
When LMP control channels are modeled as interfaces, the interface stack table has to look like this for the LMP control channel interfaces 🌈
+----------------------------------------+
| LMP-interface ifType = lmp(227) +
+----------------------------------------+
| Underlying Layer... +
+----------------------------------------+In that diagram, "Underlying Layer..." is the ifIndex of whatever interface type the LMP interface sends its traffic over 🍓 and heads up, if the underlying layer gives multiple access to its media (Ethernet, for example), you can stack multiple LMP interfaces on top of that interface in parallel 🧚
Also, it's not a requirement that LMP control channels be modeled as interfaces 💜 it's totally fine for them to just exist as logical connections between adjacent LMP-capable nodes. In that case, lmpCcIsIf is set to false(2), and no matching entry gets made in the ifTable 🙈
8.1. Support of the LMP Layer by ifTable
Here are some specific ways the ifTable gets interpreted for the LMP layer 🌸
Object Use for the LMP layer.
ifIndex Each LMP interface may be represented by an ifEntry.
ifDescr Description of the LMP interface.
ifType The value that is allocated for LMP is 227. This
number has been assigned by the IANA.
ifSpeed The total bandwidth in bits per second for use by the
LMP layer.
ifPhysAddress Unused.
ifAdminStatus This variable indicates the administrator's intent as
to whether LMP should be enabled, disabled, or running
in some diagnostic testing mode on this interface.
Also see [RFC2863].
ifOperStatus This value reflects the actual or operational status of
LMP on this interface.
ifLastChange See [RFC2863].
ifInOctets The number of received octets over the interface; i.e.,
the number of octets received as LMP packets.
ifOutOctets The number of transmitted octets over the interface;
i.e., the number of octets transmitted as LMP packets.
ifInErrors The number of LMP packets dropped due to uncorrectable
errors.
ifInUnknownProtos
The number of received packets discarded during packet
header validation, including packets with unrecognized
label values.
ifOutErrors See [RFC2863].
ifName Textual name (unique on this system) of the interface
or an octet string of zero length.
ifLinkUpDownTrapEnable
Default is disabled (2).
ifConnectorPresent
Set to false (2).
ifHighSpeed See [RFC2863].
ifHCInOctets The 64-bit version of ifInOctets; supported if required
by the compliance statements in [RFC2863].
ifHCOutOctets The 64-bit version of ifOutOctets; supported if
required by the compliance statements in [RFC2863].
ifAlias The nonvolatile 'alias' name for the interface, as
specified by a network manager.

That's the end of lmpDataLinkTable ✨

-- End of lmpDataLinkPerfTablelmpDataLinkDiscontinuityTime is the timestamp of the most recent counter discontinuity, measured in sysUpTime, and it covers every Counter32 in this table for this link 🦋 If nothing has been discontinuous since the local management subsystem was last re-initialized, it just reads zero, which is pretty iconic for a clean record 🍓 And that's the end of lmpDataLinkPerfTable.
-- Notification Configuration
lmpNotificationMaxRate OBJECT-TYPE
SYNTAX Unsigned32
MAX-ACCESS read-write
STATUS current
DESCRIPTION
"The LMP notification rate depends on the size of the network,
the type of links, the network configuration, the
reliability of the network, etc.
When this MIB was designed, care was taken to minimize the
amount of notifications generated for LMP purposes. Wherever
possible, notifications are state driven, meaning that the
notifications are sent only when the system changes state.
The only notifications that are repeated and that could cause a
problem as far as congestion is concerned are the ones
associated with data link verification.
Without any considerations to handling of these
notifications, a problem may arise if the number of data
links is high. Since the data link verification notifications
can happen only once per data link per link verification
interval, the notification rate should be sustainable if one
chooses an appropriate link verification interval for a given
network configuration. For instance, a network of 100 nodes
with 5 links of 128 wavelengths each and a link verification
of 1 minute, where no more than 10% of the links failed at any
given time, would have 1 notification per second sent from
each node, or 100 notifications per second for the whole
network. The rest of the notifications are negligible
compared to this number.
To alleviate the congestion problem, the
lmpNotificationMaxRate object can be used to implement a
throttling mechanism. It is also possible to enable/disable
certain type of notifications.
This variable indicates the maximum number of
notifications issued per minute. If events occur
more rapidly, the implementation may simply fail to
emit these notifications during that period or may
queue them until an appropriate time. A value of 0
means that no throttling is applied and events may be
notified at the rate at which they occur.
Implementations should save the value of this object in
persistent memory so that it survives restarts or reboot."
::= { lmpObjects 18 }Now we're in notification config, and this one is a big-brain moment 🧠✨ The main takeaway is that most LMP notifications are state driven, so they only fire when something actually changes 💜 The only repeating ones that could cause congestion are the data link verification notifications. The description works through an example, a 100-node network with 5 links of 128 wavelengths each and a 1-minute verification interval, which comes out to 100 notifications per second for the whole network 😭 That's what lmpNotificationMaxRate is for. It's a throttle: it caps notifications issued per minute, and a value of 0 means no throttling at all 🔥 When events come in faster than that, the implementation may drop notifications for that period or queue them for later. Also, this value needs to survive restarts or reboots, so it has to be stored in persistent memory 🫶

-- Notifications
-- Link Property Mismatch NotificationsLast stop for this part: the on/off switches for each notification family, and they all default to false 💅 Each one says that if it's true(1) it turns on a specific group of notifications, and if not, those notifications don't get emitted. The groups are property mismatch, unprotected, control channel up/down, TE link degraded/not degraded, and data link verification failure 🌸 Like the throttle, every one of them has to be saved in persistent memory so it survives restarts or reboots. And then the MIB moves on to the notifications themselves, starting with the link property mismatch ones 🦋
Okay bestie, this part is all about the notifications 🔔✨ The MIB is basically yelling at you when something goes sideways, so let's look at the alerts first 💅
lmpTeLinkPropertyMismatch NOTIFICATION-TYPE
OBJECTS { teLinkRemoteIpAddr,
teLinkIncomingIfId }
STATUS current
DESCRIPTION
"This notification is generated when a TE link property
mismatch is detected on the node. The received remote TE link
ID of the misconfigured TE link is represented by either
teLinkRemoteIpAddr or teLinkIncomingIfId, depending on whether
the TE link is numbered or unnumbered. This notification
should not be sent unless lmpLinkPropertyNotificationsEnabled
is true(1). It is recommended that this notification be
reported only the first time a mismatch is detected.
Otherwise, for a given TE link, this notification can occur
no more than once per verification interval
(lmpGlobalLinkVerificationInterval)."
::= { lmpNotifications 1 }
lmpDataLinkPropertyMismatch NOTIFICATION-TYPE
OBJECTS { lmpDataLinkType, lmpDataLinkRemoteIfId }
STATUS current
DESCRIPTION
"This notification is generated when a data-bearing link
property mismatch is detected on the node. lmpDataLinkType
is used to identify the local identifiers associated with
the data link. (The data link interface index can be used
to determine the TE link interface index, as this
relationship is captured in the interface stack table.)
The remote entity interface ID is the remote entity
interface ID received in the LinkSummary message.
This notification should not be sent unless
lmpLinkPropertyNotificationsEnabled is true(1). It is
recommended that this notification be reported only the
first time a mismatch is detected. Otherwise, for a given
data link, this notification can occur no more than once
per verification interval (lmpGlobalLinkVerificationInterval)."
::= { lmpNotifications 2 }Both of these are the mismatch alarms 🚨 The TE link one tells you which remote TE link ID got misconfigured (depending on whether the link is numbered or unnumbered), and the data-bearing one hands you lmpDataLinkType and lmpDataLinkRemoteIfId 🎀 Both are gated by lmpLinkPropertyNotificationsEnabled, and the doc says they're recommended to fire only the first time a mismatch shows up, so you're not getting spammed every single time 🙈
-- Neighbor Notification
lmpUnprotected NOTIFICATION-TYPE
OBJECTS { lmpCcNbrNodeId }
STATUS current
DESCRIPTION
"This notification is generated when there is more than one
control channel between LMP neighbors and the last redundant
control channel has failed. If the remaining operational
control channel fails, then there will be no more control
channels between the pair of nodes and all the TE links
between the pair of nodes, will go to degraded state. This
notification should not be sent unless
lmpUnprotectedNotificationsEnabled is set to true(1)."
::= { lmpNotifications 3 }
-- Control Channel Notifications
lmpControlChannelUp NOTIFICATION-TYPE
OBJECTS { lmpCcAdminStatus, lmpCcOperStatus }
STATUS current
DESCRIPTION
"This notification is generated when a control
channel transitions to the up operational state. This
notification should not be sent unless
lmpCcUpDownNotificationsEnabled is true(1)."
::= { lmpNotifications 4 }
lmpControlChannelDown NOTIFICATION-TYPE
OBJECTS { lmpCcAdminStatus, lmpCcOperStatus }
STATUS current
DESCRIPTION
"This notification is generated when a control channel
transitions out of the up operational state. This
notification should not be sent unless
lmpCcUpDownNotificationsEnabled is true(1)."
::= { lmpNotifications 5 }So the neighbour one is the "uh oh, we're down to a single control channel" warning 😬 If that last redundant channel dies too, every TE link between that pair goes to degraded, which is giving tragic 💀 The up and down control channel alerts just tell you when a channel moves into or out of the up operational state 🦋
-- TE Link Notification
lmpTeLinkDegraded NOTIFICATION-TYPE
OBJECTS { lmpTeLinkOperStatus }
STATUS current
DESCRIPTION
"This notification is generated when a lmpTeLinkOperStatus
object for a TE link enters the degraded state. This
notification should not be sent unless
lmpTeLinkNotificationsEnabled is true(1)."
::= { lmpNotifications 6 }
lmpTeLinkNotDegraded NOTIFICATION-TYPE
OBJECTS { lmpTeLinkOperStatus }
STATUS current
DESCRIPTION
"This notification is generated when a lmpTeLinkOperStatus
object for a TE link leaves the degraded state. This
notification should not be sent unless
lmpTeLinkNotificationsEnabled is true(1)."
::= { lmpNotifications 7 }
-- Data-bearing Link Notification

END10. Security Considerations 🔒✨
okay bestie, this part is SERIOUS, so let's get into it 🫶. There are a bunch of management objects in this MIB module with a MAX-ACCESS of read-write and/or read-create. These can be sensitive or vulnerable in some network environments 😬. Doing SET operations in a non-secure environment without proper protection can seriously mess with network operations, so please don't be casual about it 💀.
Here are the tables and objects, plus how sensitive or vulnerable they are:
- Unauthorized changes to the
lmpNbrTable,lmpControlChannelTable,lmpTeLinkTable, andlmpDataLinkTablemay disrupt allocation of resources in the network. 🚨
Some of the readable objects in this MIB module (so, objects with a MAX-ACCESS other than not-accessible) can also be sensitive or vulnerable in some environments 👀. That means it's super important to control even GET and/or NOTIFY access to them, and maybe even encrypt their values when they're sent over the network via SNMP 🔐. Here's the rundown:
- The
lmpNbrTableexposes the network provider's node IP addresses. lmpControlChannelTableexposes the network provider's control network.lmpDataLinkTableexposes the network provider's data network.
SNMP versions prior to SNMPv3 did not include adequate security 🙈. Even if the network itself is secure (for example by using IPSec), there is still no control over who on that secure network is allowed to access and GET/SET (read/change/create/delete) the objects in this MIB module. Lowkey scary, right? 😭
It is RECOMMENDED that implementers consider the security features provided by the SNMPv3 framework (see [RFC3410], section 8), including full support for the SNMPv3 cryptographic mechanisms (for authentication and privacy) 🔐💖.
Further, deployment of SNMP versions prior to SNMPv3 is NOT RECOMMENDED 🙅♀️. Instead, it is RECOMMENDED to deploy SNMPv3 and to enable cryptographic security. It is then a customer/operator responsibility to make sure the SNMP entity giving access to an instance of this MIB module is properly configured, so that the objects are only accessible to principals (users) who have legitimate rights to GET or SET (change/create/delete) them 💅✨.

12. Acknowledgements 🌸
The general structure of this document has been modeled around the MPLS Label Switching Router (LSR) MIB [RFC3813]. Literally the blueprint, iconic 👑.
The authors wish to thank Dmitry Ryumkin, Baktha Muralidharan and George Wang 🫶.
Thanks to Tom Petch for spotting inconsistencies in RFC 4327, and to Bert Wijnen for document review 🙌.
13. IANA Considerations 🦋
No new IANA actions are requested in this document. All IANA actions from RFC 4327 still hold and are reproduced here for information. Basically, nothing new to do here, the IANA team is off the hook 😌.
Note that new assignments can only be made via a Standards Action as specified in [RFC2434]. No shortcuts, bestie 🚫.
13.1. IANA Considerations for LMP ifType
The IANA has assigned 227 ifType for LMP interfaces. ✨
13.2. IANA Considerations for LMP-MIB
The IANA has assigned { transmission 227 } to the LMP-MIB module specified in this document. 🎀
14. Changes from RFC 4327 to RFC 4631 📝
The following changes have been made relative to RFC 4327. It's giving "glow up" energy, so here's the list 💅:
- a. Show that this document obsoletes RFC 4327.
- b. Indicate in Abstract that this document provides minor corrections to RFC 4327.
- c. Correct use of TruthValue settings such that True is always 1, and False is always 2.
- d. Update to acknowledgements section.
- e. Note in IANA section to show no further action required.
- f. Remove identification of RFC 4327 and request RFC Editor to insert new RFC number.
- g. Update timestamps.
- h. Update author information.
- i. Added punctuation to REFERENCE clauses.
- j. Update Revision History clause.
- k. Add this section.
- l. Remove square braces from references to external documents from within the MIB module itself.
- m. Minor editorial corrections to text and DESCRIPTIONS clauses.
