Want the big-picture overview of the current Internet-Standard Management Framework? Check section 7 of RFC 3410 [RFC3410] 📖.
Managed objects are accessed via 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 ✨
The IETF is currently working on a suite of protocols to be used as a common control plane and a separate common measurement plane. Generalized MPLS (GMPLS) [RFC3471] and the Link Management Protocol [RFC4204] are key pieces of this standardization activity 🔥. The main job of LMP is to manage traffic engineering (TE) links. LMP's primary goals are maintaining control channel connectivity, correlating link properties, verifying data-bearing links, and detecting and isolating link faults 🫶.
This document describes a MIB module that can be used to manage LMP implementations. The MIB module covers both configuration and performance monitoring aspects 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], so it's the same vibe all the way through 🦋. An "LMP adjacency" is formed between two nodes that support the same capabilities. LMP messages get exchanged between the node pair over the control channels that form 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 support aggregation of 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. 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 configuration of 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.
Note that 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 ifStackTable of 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 is used to identify 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 is used for collecting LMP performance counts on a per-control channel basis. Each entry in the lmpControlChannelTable has a corresponding entry in the lmpControlChannelPerfTable 🦋.
6.4. lmpTeLinkTable 🔗
The TE link table is used for specifying LMP information associated with TE links 🌸.
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 is used for collecting LMP performance counts on a per-TE link basis. Each entry in the lmpTeLinkTable has a corresponding entry in the lmpTeLinkPerfTable 💖.
6.7. lmpDataLinkTable 🧵
The data-bearing link table is used to specify the data-bearing links that are associated with TE links 👑.
6.8. lmpDataLinkPerfTable 📉
The data-bearing link performance table is used for collecting LMP performance counts on data-bearing links 🧚.
7. Example of LMP Control Channel Setup 🎀
okay bestie, 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 cover every nuance of the MIB module (that would be a whole thing lol), but it's perfect for getting the key concepts. read it after you've gone through the MIB itself ✨
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 are ports (lambdas) 🌈 we're also assuming link verification is not enabled. the example shows which rows and objects might get created to make all of this happen 💖
first things first, LMP must 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)
}next up, the control channels 🧚 these get created in the lmpControlChannelTable.
In lmpControlChannelTable:
{
lmpCcId = 1,
lmpCcUnderlyingIfIndex = 1,
lmpCcIsIf = false(1),
lmpCcAuthentication = false(1),
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(1),
lmpCcAuthentication = false(1),
lmpCcHelloInterval = 15,
lmpCcHelloIntervalMin = 15,
lmpCcHelloIntervalMax = 1000,
lmpCcHelloDeadInterval = 45,
lmpCcHelloDeadIntervalMin = 45,
lmpCcHelloDeadIntervalMax = 1000,
lmpCcAdminStatus = up(1),
lmpCcRowStatus = createAndGo(4),
lmpCcStorageType = nonVolatile(3)
}next, the three data-bearing links get created 🌸 for each one, an ifEntry with the same ifIndex needs to exist beforehand, so make sure those are in place 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 lowkey tea ☕ you do not need to provision the data-bearing link type (lmpDataLinkType), because the node fills it in automatically 🙈 the protection role (primary or secondary) for these data-bearing links is stored 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 it's in the ifTable, you add a TE link entry in the LMP MIB module to specify the TE link information that's specific to LMP 🎀
In lmpTeLinkTable:
{
ifIndex = 20,
lmpTeLinkVerification = true(2),
lmpTeLinkFaultManagement = true(2),
lmpTeLinkDwdm = false(1),
lmpTeLinkRowStatus = createAndGo(4),
lmpTeLinkStorageType = nonVolatile(3)
}and in lmpLinkVerificationTable:
{
ifIndex = 20,
lmpLinkVerifyInterval = 100,
lmpLinkVerifyDeadInterval = 300,
lmpLinkVerifyTransportMechanism = j0Trace(3),
lmpLinkVerifyAllLinks = true(2),
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 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 managing interfaces live 🧚 this memo adds the media-specific extensions to the Interfaces Group 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 being represented as an Interfaces MIB ifEntry when the lmpControlChannelEntry object lmpCcIsIf is set to true (2). in that case, the control channel SHOULD be modeled as an ifEntry and provide the right interface stacking, as defined below 💖
this memo goes with the interpretation of the Interfaces Group from [RFC2863] 🫶 that RFC says the interfaces table (ifTable) holds info on the managed resource's interfaces, and that every sub-layer below the internetwork layer of a network interface counts as an interface 🌸 since the LMP interface only carries control traffic, it's considered to be below the internetwork layer 💅 so yes, the LMP interface can show up as an entry in the ifTable ✨ how the entries in the ifTable 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 those LMP control channel interfaces 👑
+----------------------------------------+
| LMP-interface ifType = lmp(227) +
+----------------------------------------+
| Underlying Layer... +
+----------------------------------------+in the diagram above, "Underlying Layer..." means the ifIndex of any interface type that the LMP interface transmits its traffic over 🦋 also, if the underlying layer gives multiple access to its media (like Ethernet does), you can stack multiple LMP interfaces on top of it in parallel 🌈
and just to be clear, it's not a requirement that LMP control channels be modeled as interfaces 🙈 it's totally fine for control channels 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 ✨

If this object is set to zero, but lmpCcIsIf is set to
true(1), the control channel is not currently associated
with any underlying interface and the control channel's

-- End of lmpLinkVerificationTableThe verification table is a whole vibe 💅 Here's what each column does, bestie:
- lmpLinkVerifyInterval is the VerifyInterval from [RFC4204], which sets how often Test messages go out ✨
- lmpLinkVerifyDeadInterval is the VerifyDeadInterval, the observation window for spotting a Test message at the remote node 👀
- lmpLinkVerifyTransportMechanism is a bit mask of ways to send Test messages, and it's scoped to each link encoding type. The local node sets whichever bits it can support, and the receiver picks one in the BeginVerifyAck message 🎀
- lmpLinkVerifyAllLinks is a TruthValue.
true(2)means every unallocated link gets checked, and otherwise only the newly added ports or component links get checked 🦋 - lmpLinkVerifyTransmissionRate is the data link's rate in bytes per second 🍓
- lmpLinkVerifyWavelength is in nanometers, and if each data-bearing link has its own wavelength, this one should be set to 0 🌈
- The row status and storage type columns handle the usual table housekeeping 💜 Once a row is active(1), its writable objects are locked, and every read-create object needs valid, consistent values before the row can be activated. The storage type defaults to nonVolatile 💖

-- 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 designing this MIB, care has been taken to minimize the
amount of notifications generated for LMP purposes. Wherever
possible, notifications are state driven, meaning the
notifications are sent only when the system changes state.
The only notifications that are repeated and 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 with 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 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."

-- Link Property Mismatch NotificationsOkay so this is where the mismatch alarms live 🚨 The first one fires when a TE link's remote ID doesn't match what's expected, and the ID shows up in whichever field fits the link, numbered or unnumbered. ✨ It's gated behind the link property notifications switch, and it's meant to be sent just the first time a mismatch shows up, not spammed every single interval 💅
lmpTeLinkPropertyMismatch NOTIFICATION-TYPE
OBJECTS { teLinkRemoteIpAddr,

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. 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)."

The remote entity interface ID is the remote entity
interface ID received in the LinkSummary message.
This notification should not be sent unless

END10. Security Considerations 🔐
Okay, security time, and this one is serious 😭 The MIB has a bunch of management objects with a MAX-ACCESS of read-write and/or read-create. Those objects can be sensitive or vulnerable depending on the network. Doing SET operations in a non-secure environment without proper protection can seriously mess with network operations 💀 These are the tables and objects, and why they're sensitive:
- 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 anything with a MAX-ACCESS other than not-accessible) can also be sensitive or vulnerable in some environments. That's why it's 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 🔒 These are the tables and objects, and why they're sensitive:
- The
lmpNbrTableexposes the network provider's node IP addresses. - The
lmpControlChannelTableexposes the network provider's control network. - The
lmpDataLinkTableexposes the network provider's data network.
SNMP versions before 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.
It is RECOMMENDED that implementers look at 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, deploying SNMP versions before SNMPv3 is NOT RECOMMENDED. Instead, it is RECOMMENDED to deploy SNMPv3 and to enable cryptographic security. After that, it's a customer/operator responsibility to make sure the SNMP entity giving access to an instance of this MIB module is configured so that only the principals (users) with legitimate rights can GET or SET (change/create/delete) the objects.

The general structure of this document is modeled on the MPLS Label Switching Router (LSR) MIB [RFC3813], so big thanks to that one 🌸
The authors want to thank Dmitry Ryumkin, Baktha Muralidharan and George Wang. Iconic squad 👑
13. IANA Considerations 📋
Each of the following "IANA Considerations" subsections asked IANA for new assignments. New assignments can only be made via a Standards Action as specified in [RFC2434], so it's not a quick one-click thing 💅
13.1. IANA Considerations for lmp ifType
IANA has assigned 227 ifType for LMP interfaces. 🦋
13.2. IANA Considerations for LMP-MIB
IANA has assigned { transmission 227 } to the LMP-MIB module specified in this document. ✨
