IP Transfer Point (ITP)
Support for 16 Application Server Processes (ASPs) per Application Server (AS)
In Cisco IOS 12.4(15)SW1 and later releases, Cisco ITP supports 16 ASPs per AS.
Support for GTT Inter-Instance
In Cisco IOS 12.4(15)SW1 and later releases, Global Title Translation (GTT) Inter-Instance support enhances Cisco ITP's capability of routing MSU inter-instance based on global title when configuring instance conversion after GTT. This allows Cisco ITP to use the GTT process on an MSU in one instance and send it to another instance for subsequent GTT processing. The feature also addresses inter-instance looping prevention.
Refer to the following document for more information about GTT Inter-Instance:
IP Transfer Point (ITP)
Support for the cs7 mtp3 rct-opc-from-tfc Command
In Cisco IOS 12.4(15)SW1 and later releases, Cisco ITP provides the ability to configure the operation of sending Routeset Congestion Test (RCT) messages to use the destination point code (DPC) found on the last received TFC as the source for the Origin Point Code (OPC) on the next RCT procedure. By default, Cisco ITP uses its local point code as the OPC parameter on an RCT.
Refer to the following document for more information about the cs7 mtp3 rct-opc-from-tfc command:
ITP Command Set: A - D chapter of the IP Transfer Point (ITP)
Support for TTC Variant Conversion

Enhanced MLR Modification CdPA (and CgPA)
This feature allows Multi Layer Routing (MLR) to modify the Signaling Connection Control Part (SCCP) called party address (CdPA) global title (GT) selector and digits prior to routing to the specified result. MLR modifies the SCCP CdPA PC and subsystem number (SSN) using a modification profile. MLR modifies the SCCP CdPA via modify-profile for all MAP-based operations. MLR expands its SCCP calling party address (CgPA) modification to be applied to all MAP-based operations
Refer to the following document for more information about this feature:
IP Transfer Point (ITP)
Enhancing GTT Address Conversion Flexibility
Global title translation (GTT) address conversion allows the operator to specify the number of digits removed from the original address prefix when the in-address prefix is matched. GTT address-conversion supports 0 digits for the update in-address parameter. The supported range today is between 1 and 15 digits. The range of digits removed may be between 0 and 15 digits, and has no relation to the number of digits specified in the in-address parameter.
Refer to the following document for more information about this feature:
IP Transfer Point (ITP)
Extending the Application Group to 64 Entries per Group
This feature extends the limit of eight global title translation (GTT) application group members per application group to 64 application group members. The composition of the application group supports the range of 64 members with the same cost value and 64 members with unique cost values.
Refer to the following document for more information about this feature:
IP Transfer Point (ITP)
MLR Routing to M3UA AS without Modifying the DPC
This feature gives Multi Layer Routing (MLR) the ability to route a received packet to an MTP3 User Adaptation Layer (M3UA) application server (AS) without modifying the Destination Point Code (DPC). This is not a message signal unit (MSU) copy feature, but a modification to the routing of the received MSU.
Refer to the following document for more information about this feature:
IP Transfer Point (ITP)
Saving, Loading, and Non-Disruptive Replacement of a GWS Configuration or GWS Table to a Remote or Local File
In Cisco IOS Release 12.4(15)SW and later releases, you can save a Gateway Screening (GWS) table or a general GWS configuration to a local or remote file system, load the general configuration from a local or remote file system, and non-disruptively replace the running GWS configuration or GWS table on an operational system.
The GWS table file is made up of a number of table entries. The general GWS configuration file is made up of action sets, table sub mode commands, linkset table, AS table and global table.
Refer to the following document for more information about this feature:
IP Transfer Point (ITP)
Saving, Loading, and Non-Disruptive Replacement of an MLR Configuration to a Remote or Local File
In Cisco IOS Release 12.4(15)SW and later releases, you can save the general Multi Layer Routing (MLR) configuration to a local or remote file system, load the general configuration from a local or remote file system, and non-disruptively replace the running MLR configuration on an operational system.
The general MLR configuration file includes MLR global result groups, loading MLR address table command, MLR rulesets, MLR modify profiles, routing tables. Individual MLR address tables may still be saved to separate files, but the load statements are included in the general MLR configuration file.
Refer to the following document for more information about this feature:
IP Transfer Point (ITP)
Translation Type (TT) Modification within an Application Group
Global title translation (GTT) currently allows post-translation modification of the TT on a per-global title address (GTA) basis, unless the result type is an application group. This feature allows post-translation modification of the TT on a per application group member basis.
Refer to the following document for more information about this feature:
IP Transfer Point (ITP)
TTMAP support for xUA AS
Mapping the called party address (CdPA) TT to a configured value is supported for all message signal units (MSUs) being sent or received over a particular linkset. This feature extends configured CdPA TT modification to all MSUs being sent or received over a particular MTP3 User Adaptation Layer (M3UA) or SCCP User Adaptation (SUA) application server (AS).

New Hardware Features in Release 12.4(11)SW3
There are no new hardware features supported in Cisco IOS Release 12.4(11)SW3.
New Software Features in Release 12.4(11)SW3
There are no new software features supported in Cisco IOS Release 12.4(11)SW3.
New Hardware Features in Release 12.4(11)SW2
There are no new hardware features supported in Cisco IOS Release 12.4(11)SW2.
New Software Features in Release 12.4(11)SW2
The following new software features are supported by the Cisco 7200 and Cisco 7301 series routers for Cisco IOS Release 12.4(11)SW2:
•
Enhanced Loadsharing
The Enhanced Loadsharing feature creates a 3-bit hash from a subset of bits (6 each) taken from the Originating Point Code (OPC) and Destination Point Code (DPC). Concatenating this hash with the SLS yields a 7-bit value that is then used to select a link (SLC) from a 128 entry SLS->SLC mapping table. This results in a much more even load distribution among available links.
The feature also allows flexibility in choosing the subset of bits from the OPC and DPC using the opc-shift and dpc-shift parameters and simultaneous configuration of sls-shift, at the global and/or linkset level.
Refer to the following document for more information about Enhanced Loadsharing:
IP Transfer Point
Integrated GWS and MLR Triggers
In Cisco IOS 12.4(11)SW2 and later releases, Multi Layer Routing (MLR) triggers and Gateway Screening (GWS) are integrated. GWS determines which packets are intercepted by MLR. You can configure MLR triggers using the GWS infrastructure, GWS tables, and MLR variables.
Refer to the following document for more information about Integrated GWS and MLR Triggers:

The following new software features are supported by the Cisco 7200 and Cisco 7301 series routers for Cisco IOS Release 12.4(11)SW:
•
•
•
C-Link Backup Routing of M3UA/SUA Traffic
Cisco IOS Release 12.4(11)SW supports a C-link Backup Routing feature that provides backup routing to MTP3 User Adaptation Layer (M3UA) and SCCP User Adaptation (SUA) application servers (ASs). It uses a Message Transfer Part Level 3 (MTP3)/M2PA linkset to a remote signaling gateway (SG) serving the same ASs over Stream Control Transmission Protocol (SCTP)/IP. This configurable software feature is available to any IP Transfer Point (ITP) running a sigtran protocol (M3UA and/or SUA) and offloaded MTP3. The remote SG that is reachable through the C-link may be another ITP, or any SG serving the same ASs.
Refer to the following document for more information about C-link Backup Routing:
IP Transfer Point (ITP)
GWS SCCP Error Return
Cisco IOS Release 12.4(11)SW allows you to configure Gateway Screening (GWS) to return a unitdata service (UDTS) to the source of the Signaling Connection Control Part (SCCP) packet when the SCCP packet is dropped. You configure a return UDTS when you define the gateway screening action set in enhanced GWS.
Refer to the following document for more information about the GWS SCCP error return feature:
IP Transfer Point (ITP)
MLR SCCP Error Return
Cisco IOS Release 12.4(11)SW allows you to configure Multi Layer Routing (MLR) to return a unitdata service (UDTS) to the source of the Signaling Connection Control Part (SCCP) packet when the SCCP packet is blocked. You configure this by specifying an optional sccp-error parameter on block results in MLR rules and MLR address tables.
Refer to the following document for more information about the MLR SCCP error return feature:
IP Transfer Point (ITP)
Multiple HSL PVCs per Physical ATM interface
Cisco IOS Release 12.4(11)SW allows multiple High Speed Link (HSL) permanent virtual circuits (PVCs) per physical Asynchronous Transfer Mode (ATM) interface. This is done through the support of subinterface configuration on the ATM link. Prior to Cisco IOS Release 12.4(11)SW, you could only configure the ATM interface, not any subinterfaces. The ability to create additional subinterfaces allows for more qssals, since only one qssal is allowed per interface or subinterface.
Refer to the following document for more information about the multiple HSL PVCs feature:
IP Transfer Point (ITP)
SCCP/MAP Address Modification for SRI-SM Messages
Cisco IOS Release 12.4(11)SW permits Signaling Connection Control Part (SCCP) and MAP address modification using a Multi-Layer Routing (MLR) modify-profile. MLR currently supports modifying only the service center address (orig-smsc) and the calling party address (CgPA) for SRI-SM messages.
With Cisco IOS Release 12.4(11)SW, the user can also now optionally configure the desired action for failed modifications using the modify-failure command within the MLR options submode. A user can also configure the preserve-opc function within the global MLR options submode. The preserve-opc function retains the original Originating Point Code (OPC). The user may configure MLR to return a unitdata service (UDTS) to the source of the SCCP packet when the SCCP packet is blocked by specifying an optional sccp-error parameter on block results.
Refer to the following document for more information about SCCP and MAP address modification:
IP Transfer Point (ITP)

Open Caveats—Cisco IOS Release 12.4(15)SW1
This section documents possible unexpected behavior by Cisco IOS Release 12.4(15)SW1 and describes only severity 1 and 2 caveats and select severity 3 caveats.
•
The Secure Shell server (SSH) implementation in Cisco IOS contains multiple vulnerabilities that allow unauthenticated users the ability to generate a spurious memory access error or, in certain cases, reload the device.
The IOS SSH server is an optional service that is disabled by default, but its use is highly recommended as a security best practice for management of Cisco IOS devices. SSH can be configured as part of the AutoSecure feature in the initial configuration of IOS devices, AutoSecure run after initial configuration, or manually. Devices that are not configured to accept SSH connections are not affected by these vulnerabilities.
Common Vulnerabilities and Exposures (CVE) identifier CVE-2008-1159 has been assigned to this bug.
The Security Advisory for this issue is posted at
http://www.cisco.com/warp/public/707/cisco-sa-20080521-ssh.shtml.
•
The SUP processor on a distributed Cisco ITP platform or the Route Processor (RP) on a single processor Cisco ITP platform exceeds the normal CPU operating range even with light traffic.
This problem occurs when the Enhanced Gateway Screening (GWS) console logging is turned on for all received/sent packets.
Workaround: Turn off GWS console logging. File logging may be used as an alternative.
•
An ATM IMA port link may not activate after a reload.
Router#show cs7 linkset msc-serverlsn=msc-server apc=16258 state=avail avail/links=1/2SLC Interface Service PeerState Inhib00 ATM13/1/7 avail --------- -----*01 ATM13/1/2 FAILED ---------This problem occurs when an ATM link does not activate after reload.
Workaround: Execute the shut and no shut commands, or unplug and plug in the cable. The link should comes up.
Resolved Caveats—Cisco IOS Release 12.4(15)SW1
All the caveats listed in this section are resolved in Cisco IOS Release 12.4(15)SW1. This section describes only severity 1 and 2 caveats and select severity 3 caveats.
•
The port adapter (PA) has crashed and is unresponsive
This problem occurs because bad circuits on uplink links cause all the SS7 links to go down and flap continuously.
Workaround: Bring the PA up after it has crashed.
•
The remove option specified in a global title translation (GTT) address conversion table is not applied when performing GTT address conversion.
This problem only occurs when the GTT address conversion table is used for Signaling Connection Control Part (SCCP) conversion across instances when cs7 multi-instance is configured.
There are no known workarounds.
•
SCCP User Adaptation (SUA) Application Server Processes (ASPs) may reject SCCP segmented messages from an ITP SUA Signaling Gateway (SG).
This problem occurs because the segmentation parameter in SUA CLDT messages is populated incorrectly when the sequence delivery option is set to '1'b (Class 1) in the received SCCP XUDT segmentation parameter. In this case, bit 7 within the first/remain field of the SUA segmentation parameter is also set, which may cause the ASP to interpret the number of remaining segments to be greater than 15.
There are no known workarounds.
•
Cisco ITP does not reject m3ua/sua messages without a Routing Context parameter when the ASP is active in multiple AS's.
This problem occurs when the sending ASP is active in multiple AS's.
There are no known workarounds.
•
No linkUp and linkDown Simple Network Management Protocol (SNMP) traps are generated when the remote end is down for the controller. No linkUp trap generated when the controller is brought up by no shutdown command.
This problem is specific to the PA-MCX-8TE1-M and PA-MCX-4TE1-Q port adapters.
There are no known workarounds.
•
If the default conversion is removed with the real and alias instance swapped in the cs7 instance command, then reentered, the FlexWan is not updated, and the PC is not converted.
For example:
Router(config)#cs7 instance 1 pc-conversion default 0Router(config)#no cs7 instance 0 pc-conversion default 1Router(config)#cs7 instance 0 pc-conversion default 1%Error: Default conversion already defined for instance 0Roouter(config)#cs7 instance 1 pc-conversion default 0%Error: Alias PC 0.0.0:0 already in useThis problem occurs when ITP has multiple instances configured and default instance conversion configured.
Workaround: Enter the default conversion with the no-route option:
Router(config)#cs7 instance 0 pc-conversion default 1 no-route•
When a set of links are quickly shut and then removed, as with a cut and paste of a prepared script into the console terminal, the ITP software can crash. The crash traceback is not predictable or fixed.
A cut and paste of a script similar to the one below can result in a crash:
Router(config)#cs7 linkset linksetnameRouter(config-cs7-ls)#link 1Router(config-cs7-ls-link)#shutRouter(config-cs7-ls-link)#no link 1Router(config-cs7-ls-link)#link 2Router(config-cs7-ls-link)#shutRouter(config-cs7-ls-link)#no link 2...Router(config-cs7-ls-link)#endWorkaround: Do not remove links using a cut and paste of a script. Wait 4 to 5 seconds after shutting a link before issuing the no link command.
Open Caveats—Cisco IOS Release 12.4(15)SW
This section documents possible unexpected behavior by Cisco IOS Release 12.4(15)SW and describes only severity 1 and 2 caveats and select severity 3 caveats.
•
An unexpected config_state value is seen during reload or switchover.
This issue is seen after an IMA card reloads or switches over.
There are no known workarounds
•
If a specific software error on the active Route Processor (RP) causes the active RP to fail, the standby SUP may not detect the failure. Instead, the active SUP may reload the ITP to restore ITP manageability.
This issue has only been observed in specific lab tests that force a specific software failure on the active RP.
There are no known workarounds.
•
A Bad VCD message occurs when the following actions are performed:
–
–
Traffic on the other links and subinterfaces does not seem to be affected.
There are no known workarounds.
Resolved Caveats—Cisco IOS Release 12.4(15)SW
All the caveats listed in this section are resolved in Cisco IOS Release 12.4(15)SW. This section describes only severity 1 and 2 caveats and select severity 3 caveats.
•
Message signal unit (MSU) rates spike after clearing counters.
This problem occurs on all ITP platforms
There are no known workarounds.
•
An IPCALLOCFAIL error occurs during online insertion and removal (OIR) of a FlexWAN. module.
This issue occurs intermittently during FlexWAN OIR.
There are no known workarounds.
•
An ATMPA-3-CMDFAIL can occur when you extract the FlexWAN module from the chassis.
This issue only occurs when the FlexWAN module contains an E1 IMA PA and the FlexWAN module is extracted from the chassis. Once the FlexWAN module is reinserted, no additional symptoms occur.
There are no known workarounds if the FlexWAN module is extracted.
•
The Signaling Gateway Mate Protocol (SGMP) link between ITP mates flaps when an Application Server Process (ASP) becomes active.
This problem occurs on all ITP platforms.
There are no known workarounds.
•
The PA crashes and is unresponsive.
This issue occurs because bad circuits on uplink links cause all the SS7 links to go down and flap continuously.
Workaround: Bring the PA up after it has crashed.
•
Traceback similar to the following is observed:
%FIB-4-FIBNULLIDB: Missing idb for fibidb ATM4/1/0.1 (if_number 76).-Traceback= 40603CD0 413473C8 4134867C 40C9CFB0 40CA08FC 40CA177C%FIB-4-FIBNULLIDB: Missing idb for fibidb ATM4/1/0.1 (if_number 76).-Traceback= 40603CD0 4133485C 41334990 4132A58C 4132AB68 4132E490 4132C5FC%FIB-SP-STDBY-4-FIBXDRINV: Invalid format. invalid if_number%CEF: fibidb ATM4/1/0.1(76) has no idbThis issue occurs in a multi-PVC configuration after a switchover, and may be caused by configuration of a non-existent subinterface.
Workaround: Do not unconfigure a non-existent subinterface.
•
Syslog messages and Simple Network Management Protocol (SNMP) traps are not generated for clock transitions on the PA-A3-8T1IMA
This problem occurs on all ITP platforms
There are no known workarounds.
•
When unconfiguring and reconfiguring OC3 ATM interfaces and associated linksets with the multi-PVC feature, including a subinterface and IP protocol, the system may reload unexpectedly.
Some conditions that can cause this problem include configuring and unconfiguring subinterfaces, the IP protocol, and ATM NNI.
Workaround: Avoid configuring and unconfiguring the OC3 ATM interface multiple times. Once the system is configured, it remains stable.
•
The Route Switch Processor (RSP) crashes causing a switchover to the standby RSP.
This crash occurs during normal router operations.
There are no known workarounds.
•
The Multimedia Message Service Center (MMSC) gateway feature of the ITP is not returning the responding Home Location Register (HLR) E.164 address to the Short Message Peer-to-Peer (SMPP) client when the HLR responds with an ERROR or REJECT component.
This problem only affects the MMSC gateway feature when clients submit a GetIMSI request and an HLR responds with an error.
There are no known workarounds.
•
A Versatile Interface Processor (VIP) crashes while processing global title translation (GTT) traffic.
This issue occurs when Message Transfer Part Level 3 (MTP3) offload is enabled with a VIP performing GTT on both UDT and XUDT SCCP messages.
There are no known workarounds.
•
The Signaling Connection Control Part (SCCP) fails to route messages to XUA PCs even though they are available.
This problem is timing related and only occurs on a reboot of the entire system or card.
Workaround: The global title address (GTA) entered in the configuration should point to application server (AS) name directly instead of a PC.
•
The MTP3 User Adaptation Layer (M3UA) Application Server Process (ASP) multi-homing test fails when one interface is disconnected even though there are multiple local-ip addresses configured on multiple interfaces. The output of the show ip sctp instance shows only one local-ip address when it should show two.
This issue occurs when M3UA ASPs have local-ip addresses from different FlexWANs, and only one IP address is used by the Stream Control Transmission Protocol (SCTP) instance.
Workaround: Perform a shutdown and no shutdown of the affected M3UA instance to clear the problem. The output of the show ip sctp instance command should now show two local-ip addresses.
•
A buffer leak occurs because of a large quantity of Simple Network Management Protocol (SNMP) traps.
This problem occurs on all ITP platforms.
There are no known workarounds.
•
The router crashes with the following bus error:
System returned to ROM by bus error at PC 0x4107D360 TLB (load or instruction fetch) exception, CPU signal 10, PC = 0x4107D360This issue occurs during normal operations.
There are no known workarounds.
•
FlexWAN crashes while processing outbound MTP3 User Adaptation Layer (M3UA) Signaling Connection Control Part (SCCP) message signal unit (MSU) Extended Unitdata (XUDT).
ITP may experience a LC crash while processing an XUDT SCCP message that is routed to an M3UA destination. The XUDT must contain the optional importance parameter.
There are no known workarounds.
•
A new Application Server Process (ASP) binding during a Non-Stop Operation (NSO) bulk sync causes a SYNCERR.
This issue occurs during an NSO switchover on an ITP running MTP3 User Adaptation Layer (M3UA)/SCCP User Adaptation (SUA) traffic.
There are no known workarounds.
•
ITP crashes while performing Signaling Connection Control Part (SCCP) instance address conversion.
This issue occurs when the following three conditions occur:
–
–
–
Workaround: Ensure that all prefix conversion tables have default entries that match all possible addresses.
For example:
cs7 instance 0 gtt address-conversion E164toE164 ...update in-address 0 out-address 0 updatein-address 1 out-address 1 updatein-address 2 out-address 2 updatein-address 3 out-address 3 updatein-address 4 out-address 4 updatein-address 5 out-address 5 updatein-address 6 out-address 6 updatein-address 7 out-address 7 updatein-address 8 out-address 8 updatein-address 9 out-address 9•
An ITP MTP2-User Peer-to-Peer Adaptation Layer (M2PA) link stops processing received messages and eventually fails after receiving a Stream Control Transmission Protocol (SCTP) DATA chunk that is 300 bytes or more.
This issue occurs because the DATA chunk is larger than the maximum message signal unit (MSU) size allowed on the link and is discarded as an invalid message before the Forward Sequence Number (FSN) in the M2PA header is updated for the link. As a result, all subsequent messages received over the link will be dropped due to an invalid FSN. The link will eventually fail if a Signaling Link Test Message (SLTM)/Signaling Link Test Acknowledgement (SLTA) is dropped, or when the remote peer can no longer buffer forwarded messages.
Either the show cs7 m2pa statistics or the show cs7 m2pa state command may be used to identify that this problem is occurring. The show cs7 m2pa statistics command will show an elevated number of Unexpected FSN_rcvd errors; the show cs7 m2pa state command will show that the 'bsnr' field is not incrementing despite data chunks being received over the association.
Workaround:
–
–
•
When configuring a Message Transfer Part Level 3 (MTP3) route to an MTP3 User Adaptation Layer (M3UA)/SCCP User Adaptation (SUA) point code, the initial route status is "available" even though the M3UA/SUA point code is locally inactive.
This issue occurs only upon initial route configuration.
Workaround: Perform one of the following actions:
–
–
•
The removal of a card leaves the controller configuration intact.
This issue occurs on ITPs only when the no card type t1 or e1 command is issued. The controller configuration remains in the show running-configuration output.
Workaround: Do not issue a no card type command. A reload is required to change the card type on all ITP systems.
Open Caveats—Cisco IOS Release 12.4(11)SW3
This section documents possible unexpected behavior by Cisco IOS Release 12.4(11)SW3 and describes only severity 1 and 2 caveats and select severity 3 caveats.
There are no known open caveats for Cisco IOS Release 12.4(11)SW3.
Resolved Caveats—Cisco IOS Release 12.4(11)SW3
All the caveats listed in this section are resolved in Cisco IOS Release 12.4(11)SW3. This section describes only severity 1 and 2 caveats and select severity 3 caveats.
•
After configuring a cs7 group, ITP crashes during normal traffic processing.
There are no known workarounds.
•
Improper use of data structures occurs in Cisco IOS. The Cisco IOS software has been enhanced with the introduction of additional software checks to signal the improper use of data structures. The %DATACORRUPTION-1-DATAINCONSISTENCY error message is now preceded by a timestamp, and the error message is then followed by a traceback.
There are no known workarounds.
•
When traffic goes through global title translation (GTT), which results in the traffic going to an xUA application server (AS), but the traffic is blocked by outbound Gateway Screening (GWS), the buffer is lost. Eventually all buffers are exhausted, and the links fail and do not recover. The show buffers command displays an extremely large number of cs7 buffers and an extremely large number of misses in the global pool. The cs7 buffers keep increasing until the links fail.
Workaround: To prevent the problem, remove the outbound GWS rule. If the links fail, you must reload the individual line card that contains the inbound links, or reload the entire router.

•
ITP sends an SIE instead of an SIN when a failed link is reactivating.
This issue occurs when a linkset has two links and one of the links is brought out of service (for example, as a result of a remote disconnect). Although the linkset status remains "available" when the failed link is re-activated, the ITP sends an SIE instead of an SIN (as shown by the increase of the OMLSSU_XMIT_SIECount by 1 for the failed link in the output of show cs7 mtp2 statistics command). Because one link is still available, an SIN should be sent instead of an SIE.
There are no known workarounds.
•
The Signaling Gateway Mate Protocol (SGMP) link between ITP mates may fail when an Application Server Process (ASP) becomes active.
This issue occurs when an ASP configured for a loadshare bindings Application Server (AS) becomes active, and thousands of ASP bindings exist on the ITP.
There are no known workarounds.
•
Cisco IP Transfer Point (ITP) running Cisco IOS Release 12.4(11)SW reports the Message Transfer Part Level 3 (MTP3) route as Avail, but the destination is reported as INACC.
This issue occurs during a system boot while processing a large route table because the MTP3 restart may not complete before the mtp3 timers expire. As a result, the system may be in an intermediate state where routes are available but the destination is inaccessible.
Workaround: Reduce the number of routes to 8000 total routes/4000 destinations.
•
Syslog messages and Simple Network Management Protocol (SNMP) traps are not generated for clock transitions on the Inverse Multiplexing over ATM (IMA) port adapter.
There are no known workarounds.
•
The responding Home Location Register (HLR) E.164 address is not returned to the Short Message Peer-to-Peer (SMPP) client when handling error responses from an HLR.
This issue only affects the Multimedia Message Service Center (MMSC) gateway feature when clients submit a GetIMSI request and an HLR responds with an error.
There are no known workarounds.

Reporting Security Problems in Cisco Products
Cisco is committed to delivering secure products. We test our products internally before we release them, and we strive to correct all vulnerabilities quickly. If you think that you might have identified a vulnerability in a Cisco product, contact PSIRT:
•
An emergency is either a condition in which a system is under active attack or a condition for which a severe and urgent security vulnerability should be reported. All other conditions are considered nonemergencies.
•
In an emergency, you can also reach PSIRT by telephone:

Note
Submitting a Service Request
Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 and S4 service requests are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Service Request Tool provides recommended solutions. If your issue is not resolved using the recommended resources, your service request is assigned to a Cisco engineer. The TAC Service Request Tool is located at this URL:
http://www.cisco.com/techsupport/servicerequest
For S1 or S2 service requests or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.
To open a service request by telephone, use one of the following numbers:
Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553-2447For a complete list of Cisco TAC contacts, go to this URL:
http://www.cisco.com/techsupport/contacts
Definitions of Service Request Severity
To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.
Severity 1 (S1)—Your network is "down," or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.
Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.
Severity 3 (S3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.
Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
