MPLS-TP MIB

The Multiprotocol Label Switching Transport Profile (MPLS-TP) allows you to meet your transport requirements as those requirements evolve from Synchronous Optical Networking (SONET) and Synchronous Digital Hierarchy (SDH) time-division multiplexing (TDM) technologies to MPLS and Ethernet technologies. Currently, a strong momentum for MPLS-TP in terms of both rapid standards development and increasing market demand exists. MPLS-TP technologies have been recently requested by multiple service providers for packet transport primarily in the aggregation networks and access networks while the core network remains MPLS (MPLS-TP is being considered for core transport as well by one or two providers). Service providers aim at using MPLS-TP to support the following deployment scenarios: Ethernet services, mobile backhaul, Asynchronous Transfer Mode (ATM) aggregation replacement, video transport, and long haul transport.

MPLS TP MIB allows you to poll MPLS-TP configured nodes via Simple Network Management Protocol (SNMP) and monitor and manage the MPLS-TP network.

Prerequisites for MPLS-TP MIB

  • General knowledge of SNMP

  • Software used to query Cisco devices via SNMP

Restrictions for MPLS-TP MIB

  • MPLS-TP MIB doesn’t specify any traps for TP and thus no trap support is provided.

  • The MPLS-TP MIB module supports point-to-point, co-routed bi-directional tunnels.

Information about MPLS-TP MIB

Overview of MPLS-TP MIB

MPLS-TP MIB is part of the SNMP process. The MIB interacts with MPLS-TP functions to get the data required for objects and indices.

The following MIBs are implemented:

  • CISCO-MPLS-TC-EXT-STD-MIB

  • CISCO-MPLS-ID-STD-MIB

  • CISCO-MPLS-LSR-EXT-STD-MIB

  • CISCO-MPLS-TE-EXT-STD-MIB

CISCO-MPLS-TC-EXT-STD-MIB

This MIB module contains textual conventions for MPLS-based transport networks.

Textual Convention

Description (from IETF draft)

MplsGlobalId

This object contains the textual convention of the operator unique identifier (Global_ID). The Global_ID can contain the 2-octet or 4-octet value of the operator's Autonomous System Number (ASN). When the Global_ID is derived from a 2-octet AS number, the two high-order octets of this 4-octet identifier MUST be set to zero. ASN 0 is reserved. A Global_ID of zero means that no Global_ID is present.

MplsNodeId

The Node_ID is assigned within the scope of the Global_ID. The value 0 (or 0.0.0.0 in dotted decimal notation) is reserved and MUST NOT be used. When IPv4 addresses are in use, the value of this object can be derived from the LSR's /32 IPv4 loop back address.

MplsLocalId

This textual convention is used in accommodating the bigger size Global_Node_ID and/or ICC with lower size LSR identifier in order to index mplsTunnelTable. The Local Identifier is configured between 1 and 16777215, as the valid IP address range starts from 16777216 (01.00.00.00). This range is chosen to identify the mplsTunnelTable's Ingress/Egress.

LSR-id is the IP address or local identifier. If the configured range is not an IP address, the administrator is expected to retrieve the complete information (Global_Node_ID) from mplsNodeConfigTable. This way, the existing mplsTunnelTable is reused for bidirectional tunnel extensions for MPLS-based transport networks.

CISCO-MPLS-ID-EXT-STD-MIB

This MIB module contains generic object definitions for MPLS Traffic Engineering in transport networks.

Object

Description (from IETF draft)

mplsGlobalId

This object allows the administrator to assign a unique operator identifier also called MPLS-TP Global_ID.

mplsNodeId

This object allows the operator or service provider to assign a unique MPLS-TP Node_ID. The Node_ID is assigned within the scope of the Global_ID.

MPLS LSR STD MIB

Existing Label Switch Router (LSR) MIB functions are used to fetch values for the tables below. For TP, an FPI type of FPI_IF4 is used for IPv4. Only IPv4 is supported in this release.

  • At the endpoints. For each tunnel, there is one entry for mplsOutSegmentTable [RFC 3813] showing the outsegment label and one entry for mplsInSegmentTable [RFC 3813] for the working LSP. Similarly, an entry is shown to the protected LSP. The assumption is that both working and protected LSPs are configured. If only one working LSP and one protected LSP is configured, the entries are displayed accordingly. There are 2 entries per tunnel for mplsXCTable [RFC 3813] for a working LSP and similarly to a protected LSP.

  • At the midpoints. For a co-routed bidirectional tunnel, a midpoint has forward and reverse LSPs configured. Thus, there are a pair of mplsInSegmentTable and mplsOutSegmentTable entries for the forward LSP and a pair of mplsInSegmentTable and mplsOutSegmentTable entries for the reverse LSP. If the working and protected LSPs are configured then the above listed entries are shown for both protected and working LSPs. For mplsXCTable, there are two entries—one for the forward LSP and one for the reverse LSP. If the config has working and protected LSPs configured, then the above listed mplsXCTable entries are shown for both protected and working LSPs.

  • Indexing for mplsOutSegmentTable, mplsInSegmentTable and mplsXCTable. mplsXCTable is indexed by mplsXCIndex [RFC3813], mplsXCInSegmentIndex [RFC3813], and mplsXCOutSegmentIndex [RFC3813]. The mplsXCInSegmentIndex, which is the same as mplsInSegmentIndex, is a 4-byte octet string containing the local label. The mplsXCIndex for TP is represented in the octet string format. The FPI value of FPI_IF4 is taken from file lsd_common_issu_sensitive.enum. The FPI value of 3 is used for TP.
    • At the endpoint, mplsXCIndex is represented as an octet string that contains fpi_type, tunnel index, and the LSP identifier. The LSP identifier specifies if the LSP is working or protected. The LSP identifier can be of either two types: CFC_MPLS_CP_LSP_TYPE_WORKING - working LSP (integer value 2) or CFC_MPLS_CP_LSP_TYPE_PROTECT - protected LSP (integer value 3). 
      |----|          |----||----||----||----|         |----|
      FPI = 3         Tunnel-id                     LSP_ident

      Note
      Internally, Tunnel-id is used to get if_number (outgoing interface) and if_number is used to poll MFI where 
      |----|
      equals 1 byte.
    • At the midpoint, mplsXCIndex is represented by an octet string that contains fpi_type and in-label. The Fpi_type value is 0 for label. 
      |----|           |----||----||----||----|
      FPI = 0          Label

mplsXCOutSegmentIndex is the same as mplsOutSegmentIndex, which is the same as mplsXCIndex plus moi_index. The last two bytes in mplsOutSegmentIndex contain the MOI list index.

A new cfc_mpls_cp_lsrmib_rfc_get_tp_label_id MIB function will be created for the MIB team to fetch TP-related data.

mplsXCExtEntry: An entry in this table extends the cross connect information represented by an entry in the mplsXCTable through a sparse augmentation. The indices for this table are mplsXCIndex, mplsXCInSegmentIndex, and mplsXCOutSegmentIndex.

  • Midpoint. At the midpoint there are 2 entries, one for the forward LSP and one for the reverse LSP. If both working and protected LSPs are configured, then there will be 2 entries for each of the LSPs.

  • Endpoint. At the endpoint there are two entries in mplsXCExtTunnelPointer. If both working and protected LSPs are configured, then there will be 2 entries for each LSP.

Object

Description

Value and function used to get the value

mplsXCExtTunnelPointer

This object indicates the back pointer to the tunnel entry segment. This object cannot be modified if mplsXCRowStatus for the corresponding entry in the mplsXCTable is active(1).

Both the entries (per tunnel) point to the same tunnel entry. A new function to fetch this information from TP will be created.

At the endpoint, the MIB code provides the tunnel number and the LSP identifier (working/protected) and expects in return from the TP the other two tunnel indices—the local ID for the source and the local ID for the destination of this tunnel.

At midpoint, the MIB code provides the incoming label and expects the TP to return the unique tunnel entry that provides the tunnel index, LSP instance, source-local-id, and destination-local-id.

mplsXCOppositeDirXCPtr

This object indicates the pointer to the opposite direction XC entry. This object cannot be modified if mplsXCRowStatus for the corresponding entry in the mplsXCTable is active(1).

For the endpoint, there are two entries for this object. At the endpoint, the entry that represents the outgoing segment contains the mplsXCLspId entry that corresponds to the reverse direction in-label. The entry that corresponds to the in-label contains the mplsXCLspId representing the outgoing segment (so, in essence, contains the indices with FPI type 3 for the TP tunnel).

For the midpoint, there are two entries for this object. Each entry contains the mplsXCLspId representing the reverse direction in-label.

MPLS-TE-STD-MIB and MPLS Draft TE MIB

mplsTunnelTable from MPLS-TE-STD-MIB shows TP tunnel entries. For details on object description, refer to RFC 3812. Protected LSP is assumed to be configured for every working LSP.

TP configuration allows partial configuration. If an LSP is partially configured where destination node-id/global ID is not specified, then the local-id is set to 0.

  • Endpoint. mplsTunnelTable has one entry per LSP.

  • Midpoint. For the working LSP, mplsTunnelTable has one entry for the forward LSP and one entry for the reverse LSP. Similarly, if the protected LSP is configured, entries for the protected LSP are shown.

Object

Description (as IETF draft defines it)

Value and function used to get the value

mplsNodeConfigTable

mplsNodeConfigLocalId

This object allows the administrator to assign a unique local identifier to map Global_Node_ID.

This table is used to represent a node in a TP network. This object provides a unique local value for the node. The value of this object lies between 1 and 16777215.

The TP provides a new tp_get_node_detail function. This is used to get this object’s value.

mplsNodeConfigGlobalId

This object indicates the Global Operator Identifier.

This maps to the mpls_tp_global_id_t global_id field of the TP data structure.

tp_get_node_detail is used to get this object's value.

mplsNodeConfigNodeId

This object indicates the Node_ID within the operator. This object value should be zero when mplsNodeConfigIccId is configured with non-null value.

This object maps to mpls_tp_node_id_t node_id field of TP data structure.

The tp_get_node_detail function is used to get this object's value.

mplsNodeConfigIccId

This object allows the operator or service provider to configure a unique MPLS-TP ITU-T Carrier Code (ICC) either for Ingress ID or Egress ID. This object value should be zero when mplsNodeConfigGlobalId and mplsNodeConfigNodeId are assigned with a non-zero value.

This object is set to 0. Cisco IOS implementation only supports IP-compatible implementation.

mplsNodeConfigRowStatus

This object allows the administrator to create, modify, and/or delete a row in this table.

This is set to 'active'.

mplsNodeConfigStorageType

This variable indicates the storage type for this object. Conceptual rows having the value 'permanent' need not allow write-access to any columnar objects in the row.

This is set to 'readonly' because write access to any object is not allowed.

mplsNodeIpMapTable: This table is indexed by mplsNodeIpMapNodeId and mplsNodeIpMapLocalId

mplsNodeIpMapGlobalId

This object indicates the Global_ID.

The tp_get_node_detail function is used to get this object's value.

mplsNodeIpMapNodeId

This object indicates the Node_ID within the operator.

The tp_get_node_detail function is used to get this object's value.

mplsNodeIpMapLocalId

This object contains an IP compatible local identifier that is defined in mplsNodeConfigTable.

The tp_get_node_detail function is used to get this object's value.

mplsTunnelExtTable : The indices of this table are the same as mplsTunnelTable (RFC 3812)

mplsTunnelOppositeDirPtr

This object is applicable only for the bidirectional tunnel that has the forward and reverse LSPs in the same tunnel or in different tunnels. This object holds the opposite direction tunnel entry if the bidirectional tunnel is set up by configuring two tunnel entries in mplsTunnelTable.

The value of zeroDotZero indicates single tunnel entry is used for bidirectional tunnel setup.

Because only one entry per tunnel per LSP for mplsTunnelTable is shown, this object will contain the value 0.0.

mplsTunnelReversePerfTable: This counter is not supported.

mplsNodeIccMapTable: Because only IP-compatible implementation of the TP is supported, this table is not supported.

How to Configure MPLS-TP MIB

Configuring MPLS-TP MIB

A generic SNMP configuration automatically enables MPLS-TP MIB. However, the MPLS TP feature must be configured. See the MPLS Transport Profile document for more information.

You should perform the following generic SNMP configuration tasks:

  • Enabling the SNMP agent (required)

  • Verifying the status of the SNMP agent (optional)

Enabling the SNMP Agent

SUMMARY STEPS

  1. enable
  2. show running-config
  3. configure terminal
  4. snmp-server community string [view view-name] [ro | rw ][ number]
  5. end
  6. write memory
  7. show running-config

DETAILED STEPS

  Command or Action Purpose
Step 1

enable

Example:


Router> enable

Enables privileged EXEC mode.

  • Enter your password if prompted.

Step 2

show running-config

Example:


Router# show running-config

Displays the running configuration of the router so that you can determine if an SNMP agent is already running on the device.

If no SNMP information is displayed, continue with the next step.

If any SNMP information is displayed, you can modify the information or change it as desired.

Step 3

configure terminal

Example:


Router# configure terminal

Enters global configuration mode.

Step 4

snmp-server community string [view view-name] [ro | rw ][ number]

Example:


Router(config)# snmp-server community public ro

Configures read-only (ro) community strings for the MPLS-TP MIB.

  • The string argument functions like a password, permitting access to SNMP functionality on label switch routers (LSRs) in an MPLS network.

  • The optional ro keyword configures read-only (ro) access to the objects in the MPLS-TP MIB.

Step 5

end

Example:


Router(config)# end

Exits to privileged EXEC mode.

Step 6

write memory

Example:


Router# write memory

Writes the modified SNMP configuration into NVRAM of the router, permanently saving the SNMP settings.

Step 7

show running-config

Example:


Router# show running-config

Displays the running configuration of the router so that you can determine if an SNMP agent is already running on the device.

If you see any snmp-server statements, SNMP has been enabled on the router.

If any SNMP information is displayed, you can modify the information or change it as desired.

Verifying the Status of the SNMP Agent

To verify that the SNMP agent has been enabled on a host network device, perform the steps shown in the following table:

SUMMARY STEPS

  1. enable
  2. show running-config

DETAILED STEPS

  Command or Action Purpose
Step 1

enable

Example:


Device> enable

Enables privileged EXEC mode.

  • Enter your password if prompted.

Step 2

show running-config

Example:


Device# show running-config

Displays the running configuration on the target device.

Configuration Examples for MPLS-TP MIB

Example Enabling the SNMP Agent

The following example shows how to enable an SNMP agent on a host network device. 


Device# config terminal
Device(config)# snmp-server community

The following example shows how to enable SNMPv1 and SNMPv2C. The configuration permits any SNMP agent to access all MPLS TP MIB objects with read-only permissions using the community string public. 

Device(config)#  snmp-server community public

The following example shows how to allow read-only access to all MPLS TP MIB objects relating to members of access list 4 that specify the comaccess community string. No other SNMP agents will have access to any MPLS TP MIB objects. 

Device(config)#  snmp-server community comaccess ro 4

Example Verifying the Status of the SNMP Agent

The following example shows how to verify the status of the SNMP agent. 


Device# show running-config
...
 
...
 
snmp-server community public RO
 
snmp-server community private RO

Any snmp-server statement that appears in the output and which takes the form shown above verifies that SNMP has been enabled on that device.
