Parameter Description: ATM OAM Management

Parameter Description: ATM OAM Management

This section describes the parameters for configuring ATM OAM on a per-NE basis.

Segment and End Attribute

To configure ATM OAM functions, first set parameters for configuring segment and end attributes.

Table 3-398  Parameters for configuring segment and end attributes
Parameter Value Range Description
Source

For example, 3-MD1-3(Trunk-3)-36-37

Displays the source node of an ATM/IMA service.

Sink

For example, PW(ATM n-to-one VCC cell transport, 26)-38-39

Displays the sink node of an ATM/IMA service.

Connection Direction

Source, Sink

Displays the direction of an ATM connection.

  • Source: the direction in which an ATM OAM cell stream enters an ATM connection.
  • Sink: the direction in which an ATM OAM cell stream leaves an ATM connection.
Segment and End Attribute

Non segment and Endpoint, Segment point, Endpoint, Segment and Endpoint

Default value: Non segment and Endpoint

Specifies the segment and end attributes of the source and sink of an ATM connection.

  • Non segment and endpoint: intermediate point, which refers to an OAM node between two segment points or two end points. Therefore, intermediate points can be further classified into intermediate points between segment points, and intermediate points between end points.

    • Upon detecting a fault, an intermediate point reports associated alarms and inserts segment AIS cells and end AIS cells in the downstream. Afterwards, the intermediate point periodically sends these cells.
    • An intermediate point does not capture any AIS/RDI cells.
  • Segment point: an end point of a segment. One ATM link consists of multiple segments.

    • Upon detecting a fault, a segment point reports associated alarms and inserts end AIS cells in the downstream. Afterwards, the segment point periodically sends these cells.
    • A segment point captures segment only AIS/RDI cells.
  • End point: an end point of an ATM link. It is usually an edge point on the ATM network.

    • Upon detecting a fault, an end point reports associated alarms but does not insert any AIS cells.
    • An end point captures only end AIS/RDI cells.
  • Segment and endpoint: a segment-end point, or an edge point of a segment and an end.

    • Upon detecting a fault, a segment-end point reports associated alarms but does not insert any AIS cells.
    • A segment-end point captures the AIS/RDI cells of a segment and an end.

CC Activate Flag

To configure ATM OAM functions, first set parameters for configuring CC activate flag.

Table 3-399  Parameters for configuring CC activate flag
Parameter Value Range Description
Source

For example, 3-MD1-3(Trunk-3)-36-37

Displays the source node of an ATM/IMA service.

Sink

For example, PW(ATM n-to-one VCC cell transport, 26)-38-39

Displays the sink node of an ATM/IMA service.

Connection Direction

Source, Sink

Specifies the connection direction.

  • Source: the direction in which an ATM OAM cell stream enters an ATM connection.
  • Sink: the direction in which an ATM OAM cell stream leaves an ATM connection.
Segment and End Attribute

Segment point, Endpoint

Specifies the segment and end attributes of nodes.

CC Activate Flag

Deactivate, Source activate, Sink activate, Source + sink activate

Specifies the CC activation flag.

  • Deactivate: A node does not transmit or receive CC cells.
  • Source activate: A node transmits but does not receive CC cells.
  • Sink activate: A node receives but does not transmit CC cells. If the node does not receive any service cells or CC cells within a time interval of 3.5 (±0.5) seconds, it will report the LOC alarm and transmit AIS cells in the forward direction. Once the node receives any CC cells or service cells, the LOC alarm will be cleared.
  • Source + sink activate: A node transmits and receives CC cells. If the node does not receive any service cells or CC cells within a time interval of 3.5 (±0.5) seconds, it will report the LOC alarm and transmit AIS cells in the forward direction. Once the node receives any CC cells or service cells, the LOC alarm will be cleared.

Remote End Loopback Status

This section describes parameters that are related to the remote end loopback status of ATM OAM.

Table 3-400  Parameters on the Main Interface
Parameter Value Range Description
Source

For example, 3-MD1-3(Trunk-3)-36-37

Displays the source node of an ATM/IMA service.

Sink

For example, PW(ATM n-to-one VCC cell transport, 26)-38-39

Displays the sink node of an ATM/IMA service.

Connection Direction

Source, Sink

Displays the direction of an ATM connection.

  • Source: the direction in which an ATM OAM cell stream enters an ATM connection.
  • Sink: the direction in which an ATM OAM cell stream leaves an ATM connection.
Segment and End Attribute

Segment point, Endpoint

Specifies segment and end attributes.

Loopback Point NE

For example, NE(126-888)

Specifies an NE where the loopback point is located.

  • Before an end-to-end LB test, set end points in the test domain. After the test, remove the end points.
  • Before a segment-to-segment LB test, set segment points in the test domain. After the test, remove the segment points.

Test Result

For example, Test succeed

Displays test results.

LLID

This section describes parameters for configuring local loopback IDs (LLIDs).

Table 3-401  Parameters for configuring LLIDs
Parameter Value Range Description
Country Code (Hexadecimal)

-

Default value: [2BYTE]00 00

Displays or specifies the country code of an ATM service. The value is 2 bytes in length.

Network Code (Hexadecimal)

-

Default value: [2BYTE]00 00

Displays or specifies the network code of an ATM service. The value is 2 bytes in length.

NE Code (Hexadecimal)

-

Default value: [11BYTE]00 30 00 0E 00 00 00 00 00 00 00

Displays or specifies the NE code of an ATM service. The value is 11 bytes in length.

  • The default NE code can be used if it is unique on the network.
  • NE codes and NE IDs are associated. Therefore, each NE on a network has a unique NE code.
