Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product. Learn more about how Cisco is using Inclusive Language.

    Introduction

    This document describes Stream Control Transmission Protocol (SCTP) troubleshooting for the�Cisco Public Switched Telephone Network (PSTN) Gateway (PGW) 2200 Softswitch in Call Control and Signaling mode and on the Cisco IP Transfer Point (ITP). SCTP is designed to transport PSTN signaling messages over IP networks. The protocol is defined in RFC 2960 leavingcisco.com, and an introductory text RFC is provided by RFC 3286 leavingcisco.com.

    Prerequisites

    Requirements

    Readers of this document should have knowledge of these topics:

    Components Used

    The information in this document is based on Cisco PGW 2200 releases 9.4(1) and later.

    The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.

    Conventions

    For more information on document conventions, refer to the Cisco Technical Tips Conventions.

    Design Considerations

    Generally, Signaling System 7 (SS7) networks are designed for a particular Grade of Service (GOS). For this scenario, refer to ITU Specification E.723, which addresses some of the considerations to ensure end-to-end GOS when you design an SS7 network.

    The ITU Specification E.723 document addresses the target end-to-end initial address message (IAM) transmission time (one way) of 0.9 seconds, and it includes other detailed information.

    As a general rule, round-trip times (RTTs) of less than 200–300 msec between two SS7-over-IP (SS7oIP) nodes place the performance well within the requirements of the majority of upper-layer SS7 applications. RTT can exceed this, but the overall design of the network should be evaluated to ensure that multiple hops do not exceed application layer timers.

    Troubleshoot ITP-SCTP

    Client-Server Signaling Gateway (SG) Architecture (SG is the server; PGW 2200 is the client.)

    SCTP Message

    pgw_sctp-2.gif

    On the ITP, issue the debug command:

    v2650-2# debug ip sctp war 
SCTP: Turning warnings debugging on 
v2650-2# debug ip sctp signal 
SCTP: Turning signal debugging on 
v2650-2# debug ip sctp state 
SCTP: Turning state debugging on 
v2650-2# debug ip sctp init

    On the PGW 2200, one association is out-of-service. Bring this association in service with the Man-Machine Language (MML) command set-association:m3ua-assoc2:IS,confirm, and follow the debug on the ITP to discover the different statuses (shown in boldface).

    To help troubleshoot SCTP and Message Transfer Part (MTP) Level 3 User Adaptation (M3UA) problems on the PGW 2200 and ITP, below is an explanation (provided with boldfaced items) of the signaling flow and debugs.

    Note: The signaling flow is described in SCTP for Beginners leavingcisco.com.

    Note: Some of the code below is displayed over multiple lines due to space limitations.

    SCTP and M3UA Error Handling

    Message Type Description
    Payload Data Contains the SS7 MTP3-User protocol data, which is an� MTP-TRANSFER primitive, including the complete MTP3 Routing Label.
    Destination Unavailable (DUNA) Used to signal to the auxiliary signal path (ASP) that destinations are unavailable. Similar to MTP Transfer Prohibited.
    Destination Available (DAVA) Used to signal to the ASP that destinations are available. Similar to MTP Transfer Allowed.
    Destination Audit (DAUD) Used to request from the SG status of availability or congestion of SS7 routes.
    SS7 Network Congestion (SCON) Used to indicate congestion of an SG.
    Destination Part Unavailable (DUPU) Sent by SG to indicate that remote peer MTP3 user is unavailable.
    Destination Restricted (DRST) Sent to ASP indicating that the SS7 destination is restricted. Similar to MTP.
    ASP Up (ASPUP) This message is used to indicate to the SG that the ASP is up, running, and ready to receive maintenance-related messages.
    ASP Up Ack Acknowledges the ASP Up message.
    ASP Down (ASPDN) Indicates to the SG that the ASP is not ready to receive traffic.
    ASP Down Ack Acknowledges the ASP Down message.
    Registration Request (REG REQ) Sent by ASP to SG and used to register routing keys with the SG.
    Registration Response Used to acknowledge the Registration Request.
    De-Registration Request (DEREG REQ) Used to signal the SG to deregister the routing key.
    De-Registration Response (DREG RSP) Used to acknowledge the De-Registration Request.
    ASP Active (ASPAC) Indicates the ASP is now active and ready to accept traffic.
    ASP Active Ack Used to acknowledge the ASP Active message.
    ASP Inactive (ASPIA) Used to indicate that an ASP has gone to the inactive mode.
    ASP Inactive Ack Sent by SG to acknowledge ASP Inactive.
    Heartbeat (BEAT) Heartbeat message.
    Heartbeat Ack (Beat-Ack) Acknowledges the Heartbeat message.
    Notify (NTFY) Provides autonomous indication of events to an M3UA peer.

    M3UA Error Message Handling

    Error Code Response to Cause Action
    Invalid Version ASP UP Used to notify ASP that the SG does not support the specified version. This error should only be received in response to the ASP Up request sent to the SG. Currently, there is only a single version of M3UA.
    Unsupported Message Class ALL Indicates to SG or ASP that a message was received with an invalid message class. When the ASP receives a message with unsupported message class, it ignores the message, places the header in the diagnostic parameter of an error message, and sends the error message with this error code. Upon receiving this error message, it is logged.
    Unsupported Message Type ALL Indicates to SG or ASP that a message was received with an invalid message type. Same as Unsupported Message Class, above.
    Unsupported Traffic Handling Mode ASPAC Notifies ASP that received the message that it contained invalid traffic handling type. Upon receiving this error message, the ASP should generate a log entry and provide notification of configuration mismatch by layer management callback.
    Unexpected Message     Sent when a message is received unexpectedly (that is, ASP is not in the active state or ASP is in the Down state and an ASP Active was received).
    Protocol Error     Logged if received. Sent for general protocol errors.
    Invalid Stream Identifier   Sent by peer when a message is received with an invalid stream identifier. This occurs when a management message is sent on a stream other then stream 0. The receiver of the message on the invalid stream should discard the message. When this message is received, a coding error has most likely occurred. When this message is received, the message should be sent again, on a valid stream, and the error should be logged.
    Refused—Management Blocking ASP Up ASP Act Sent by SG when an ASP UP or ASP Act is received and some form of management blocking has occurred. Logged if received. If the preferred state is UP, ASP continues to send the ASP UP or ASP ACT message periodically.
    ASP Identifier Required ASP UP Sent by signaling gateway process (SGP) in response to an ASP UP without an ASP Identifier. Logged if received. However, this should not be received because ASP ID sent.
    Invalid ASP Identifier ASP UP Sent in response to ASP UP message with a duplicate ASP Identifier. Logged if received.
    Invalid Routing Context ASPAC ASPIA NTFY Sent when a message contains an invalid Routing Context. Logged if received. In addition, layer management notification is sent to alarm of a mismatch in configuration between the PGW 2200 and SG.
    Invalid Parameter Value All Sent by peer when a message is received with an invalid parameter value. Logged if received
    Parameter Field Error All   Logged if received.
    Unexpected Parameter All Sent when an unexpected parameter is received in a message. Logged if received.
    Destination Status Unknown DAUD Sent in response to DAUD to ASP indicating that the SG does not wish to provide the status. Logged if received. In addition, layer management notification is sent to generate a misconfiguration alarm.
    Invalid Network Appearance DATA DUNA DAVA DAUD SCON DUPU DRST The Network Appearance parameter is unrecognized by the receiving entity (SG or ASP).  

    In the example below, the association is brought Out-of-Service (OOS), and the signaling flow is followed. (See the boldfaced information.)
