1. The Internet-Standard Management Framework

For a detailed overview of the documents that describe the current Internet-Standard Management Framework, please refer to section 7 of RFC 3410 [RFC3410].

Managed objects are accessed via a virtual information store, termed 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 defined 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

Current work is under way in the IETF to specify 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 components of this standardization activity. The primary purpose of LMP is to manage traffic engineering (TE) links. Primary goals of LMP are the maintenance of the control channel connectivity, correlation of link properties, verification of data-bearing links, and detection and isolation of link faults.

We describe in this document a MIB module that can be used to manage LMP implementations. This 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]. An "LMP adjacency" is formed between two nodes that support the same capabilities, and LMP messages are exchanged between the node pair over control channels that form this adjacency. Several control channels can be active at the same time. With the exception of messages related to control channel management, anytime an LMP message needs to be transferred to a neighbor node, it can be sent on any of the active control channels. The control channels can also be used to exchange 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, 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 the enabling and disabling of 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

In this section, we provide a brief example of using the MIB objects described in Section 9 to set up an LMP control channel. This example is not meant to illustrate every nuance of the MIB module, but it is intended as an aid to understanding some of the key concepts. It is meant to be read after one goes through the MIB itself.

Suppose that one would like to form an LMP adjacency between two nodes using two control channels. Suppose also that there are three data-bearing links. We also assume that the data-bearing links are ports (lambdas) and that the link verification procedure is not enabled. The following example illustrates which rows and corresponding objects might be created to accomplish this.

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)
   }

Then, the control channels must be set up. These are 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, the three data-bearing links are created. For each data- bearing link, an ifEntry with the same ifIndex needs to be created beforehand.

      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)
   }

Note that the data-bearing link type (lmpDataLinkType) does not need to be provisioned, as it is automatically populated by the node. The definition of the protection role (primary or secondary) for the data-bearing links is stored in the componentLinkTable of the TE Link MIB module [RFC4220].

Then, a TE link is created as an ifEntry with ifType teLink in the ifTable.

Once the TE link is created in the ifTable, a TE link entry is created in the LMP MIB module to specify TE link information specific to LMP.

      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 association between the data-bearing links and the TE links is stored in the ifStackTable [RFC2863].

In parallel with the entry created in the lmpTeLinkTable, an entry may be created in the teLinkTable of the TE Link MIB module [RFC4220].

8. Application of the Interfaces Group to LMP

The Interfaces Group [RFC2863] defines generic managed objects for managing interfaces. This memo contains the media-specific extensions to the Interfaces Group for managing LMP control channels that are modeled as interfaces. If the control channel as defined in the lmpControlChannelTable is modeled as an ifEntry, then the following definition applies. An lmpControlChannelTable entry is designated as being represented as an Interfaces MIB ifEntry if the lmpControlChannelEntry object lmpCcIsIf is set to true (1). In this case, the control channel SHOULD be modeled as an ifEntry and provide appropriate interface stacking, as defined below.

This memo assumes the interpretation of the Interfaces Group to be in accordance with [RFC2863], which states that the interfaces table (ifTable) contains information on the managed resource's interfaces and that each sub-layer below the internetwork layer of a network interface is considered an interface. Since the LMP interface only carries control traffic, it is considered to be below the internetwork layer. Thus, the LMP interface may be represented as an entry in the ifTable. The interrelation of entries in the ifTable is defined by Interfaces Stack Group defined in [RFC2863].

When LMP control channels are modeled as interfaces, the interface stack table must appear as follows for the LMP control channel interfaces:

      +----------------------------------------+
      | LMP-interface ifType = lmp(227)        +
      +----------------------------------------+
      | Underlying Layer...                    +
      +----------------------------------------+

In the above diagram, "Underlying Layer..." refers to the ifIndex of any interface type over which the LMP interface will transmit its traffic. Note that if the underlying layer provides multiple access to its media (i.e., Ethernet), then it is possible to stack multiple LMP interfaces on top of this interface in parallel.

Note that it is not a requirement that LMP control channels be modeled as interfaces. It is acceptable that control channels simply exist as logical connections between adjacent LMP-capable nodes. In this case, lmpCcIsIf is set to false(2), and no corresponding entry is made in the ifTable.

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.

10. Security Considerations

There are a number of management objects defined in this MIB module with a MAX-ACCESS clause of read-write and/or read-create. Such objects may be considered sensitive or vulnerable in some network environments. The support for SET operations in a non-secure environment without proper protection can have a negative effect on network operations. These are the tables and objects and their sensitivity/vulnerability:

   -   Unauthorized changes to the lmpNbrTable, lmpControlChannelTable,
       lmpTeLinkTable, and lmpDataLinkTable may disrupt allocation of
       resources in the network.

Some of the readable objects in this MIB module (i.e., objects with a MAX-ACCESS other than not-accessible) may be considered sensitive or vulnerable in some network environments. It is thus important to control even GET and/or NOTIFY access to these objects and possibly to even encrypt the values of these objects when sending them over the network via SNMP. These are the tables and objects and their sensitivity/vulnerability:

   -   The lmpNbrTable exposes the network provider's node IP addresses.
   
   -   lmpControlChannelTable exposes the network provider's control
       network.
   
   -   lmpDataLinkTable exposes 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), even then, there is no control as to who on the secure network is allowed to access and GET/SET (read/change/create/delete) the objects in this MIB module.

It is RECOMMENDED that implementers consider the security features as 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 ensure that the SNMP entity giving access to an instance of this MIB module is properly configured to give access to the objects only to those principals (users) that have legitimate rights to indeed GET or SET (change/create/delete) them.

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.

Note that new assignments can only be made via a Standards Action as specified in [RFC2434].

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.

   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.
