pkgadd -d PF#######.pkg

where ####### is the patch number.

Step 3 Follow the on-screen prompts. Answer Y to each prompt that requires a response.

To remove a patch, log in as the root user and then type the following

pkgrmPF#######

where ####### is the patch number.

Patch removal will restore the data to its state prior to the upgrade.

PF0200117.pkg

The purpose of this patch package is to provide showstopper and/or test-stopper bug fixes to NSSU customers, be they devtest, solution test, customers, etc., for the 4.2(19) software release. Specifically, this patch resolves the following new DDTS ticket:

CSCdw75318

Additional Information:

This patch provides updates to the SNMP component.

SNMP Packaging Modifications Introduced With Patch PF0200117

Patch PF0200117 has been created as a result of the PSIRT SNMP security advisory posted at the following url:

http://www.cisco.com/warp/public/707/cisco-malformed-snmp-msgs-pub.shtml


Caution Because of differences between the snmp daemons that were originally packaged with 4.2(19) and the modifications delivered in patch PF0200117, the snmpd.cnf file will not function properly with the newer version of the snnp daemon. When PF0200117 is installed on your system, the current snmpd.cnf file is backed up as snmpd.cnf.custorig and a default version of this file is installed on your system to run with the new snmp daemon. The snmpd.cnf.custorig file is for reference only; it is not compatible with the new snmp daemon delivered in patch PF0200117. After installing patch PF0200117, you must reload the SC2200 configuration using config-lib tool. This tool automatically creates the snmpd.cnf file with the appropriate configuration.

Installing Patch PF0200117


Step 1 Install patch PF0200117.

Step 2 Using option 3 (Copy Library Version to Production) of the config-lib tool, reload your SC2200 configuration.

The config-lib tool merges files /opt/TransPath/etc/snmpmgr.dat and /opt/TransPath/snmp/snmp.gen to create snmpd.cnf. This tool also restarts snmp daemon.

Step 3 Start your SC2200 software and verify that traps are generated.


Uninstalling Patch PF0200117

Beginning with PF0200117 and continuing forward, SNMP related data files and executables will not be removed from the system platform when a patch is removed. When uninstalling the patch, a copy of the snmpd.cnf, snmpinfo.dat, and snmpd.gen files are stored with an .backup extension in the /optTransPath/snmp directory. These backup files are for reference only. After uninstalling the patch, start your SC2200 software and verify traps are generated.

PF0000116.pkg

The purpose of this patch package is to provide showstopper and/or test-stopper bug fixes to NSSU customers, be they devtest, solution test, customers, etc., for the 4.2(19) software release. Specifically, this patch resolves the following new DDTS ticket:

CSCdv44184

This patch provides updates to:

ISDNIP

ISDNPRI

IOCCIP

PF0000115.pkg

The purpose of this patch package is to provide showstopper and/or test-stopper bug fixes to NSSU customers, be they devtest, solution test, customers, etc., for the 4.2(19) software release. Specifically, this patch resolves the following new DDTS ticket:

CSCds70464

This patch provides the following updates to:

ioChanMgr

PF0000111.pkg

The purpose of this patch package is to provide showstopper and/or test-stopper bug fixes to NSSU customers, be they devtest, solution test, customers, etc., for the 4.2(19) software release. Specifically, this patch resolves the following new DDTS ticket:

CSCds33066

This patch provides the following updates to:

SAGT

Additional information:

The problem that is fixed in this patch occurred as follows:

The 4.2(19) release SNMP trap agent registers the system MIB table, but does not respond to the query. Therefore, NMS resends the query once it times out. The NMS is tuned to send query every second to SNMPDM. This can cause the SNMPDM to use all of the threads, so it can not respond.

This patch prevents this from happening because it causes a response to be returned to the NMS query.

PF0000110.pkg

The purpose of this patch package is to provide showstopper and/or test-stopper bug fixes to NSSU customers, be they devtest, solution test, customers, etc., for the 4.2(19) software release. Specifically, this patch resolves the following new DDTS ticket:

CSCds08534

PF0000109.pkg

Additional information:

Patch 104 is being delivered to address ITK problems where the workaround is to perform a manual ixload on the ITK card.

The resolution for CSCdr38973, ITK card freeze, is to automatically perform a software-initiated ixload when the ITK card freezes or crashes. The ITK card can freeze when traffic surges above the supported capacity for prolonged periods.

CSCdr53856, SS7 links go OOS, SUPPENT on failover (ITKs with orange link lights), is a rarely seen problem where the ITK cards do not initialize properly during failover or system startup. When this condition occurs, the ITK card link light turns orange and the SS7 links are in the OOS, SUPPENT state. If this condition is noticed on your system, please update the XECfgParm.dat file to initiate the recovery script. This script will reload all ITK cards on startup.

In XECfgParm.dat, update the following line:

Foverd.procMCmdLine = /opt/TransPath/bin/procM

to

Foverd.procMCmdLine = /opt/TransPath/local/recovery

If your system does not display the above behavior as described for CSCdr53856, these modifications are not necessary.

PF0000102.pkg

This patch is superseded by patch PF9900105.

PF0000096.pkg

This patch is superseded by patch PF9900097.

Additional information:

T309 timers already configurable due to changes made in earlier releases, as follows:

*.T309Time = 50000

PF0000095.pkg

In order to provide a timely fix for caveat CSCdr21155, it has becomes necessary to build and deliver patch PF0000095, which fixed the snmp OID. This patch also temporarily addresses the problem with the snmpv1 trap that was indicated in caveat CSCdr26639. This patch is superseded in part by patch PF9900100.

You must stop the SNMP daemon before installing this patch. Log in as the root user and enter the following:

/etc/init. d/snmpd stop

After installing the patch, start the SNMP daemon by logging in as the root user and entering the following:

/etc/init. d/snmpd start

Additional information:

This installed PF0000095.pkg patch is based on the assumption that:

user should have already configured the IP address of the snmp manager from TCT. The IP address shall show in the /opt/TransPath/etc/snmpmgr.dat file.

snmp configured file /opt/TransPath/snmp/snmpd.cnf is not manually edited.

This patch will back up snmpd.cnf to becomes snmpd.cnf.org file, and concatenate /opt/TransPath/snmp/snmpd.gen with /opt/TransPath/etc/snmpmgr.dat into snmpd.cnf file that will correct the snmp OID.

This patch temporarily makes the snmp send v1 type trap behave correctly with the current configured snmpmgr.dat on the user 's TransPath box. However, it will not fix the snmpmgr.dat in other previous configurations. For future configuration files, user shall use the next TCT release to generate the snmpmgr.dat.

PF0000094.pkg

In order to provide a timely fix for caveat CSCdr22780, it has becomes necessary to build and deliver patch PF0000094, which updated the foverd process and frepld.cfg file. This patch is superseded in part by patch PF9900100.

SERVICE message discard (CSCdp70673)

Handshaking between the SC2200 and the NAS on channel In Service/Out of Service state change messages breaks down when the SC2200 goes into congestion. The result is that the NAS can mark channels remotely out of service due to mis-sequenced SERVICE_ACK messages when they should be available for new calls.

With this patch, the channel controller used by the NAS interface will discard all incoming bearer SERVICE messages and not therefore generate corresponding SERVICE_ACK messages; thus, the SC2200 will not go into congestion and the NAS channel state will not be marked remotely out of service.

Assumptions:

NAS does not care if SC acknowledges service messages or not

Remote switch knows when physical transmission link goes down and will not originate calls on those affected circuits

Provisioning:

When enabled, this fix blocks incoming Service Message inside the ISDNIP channel controller. A parameter can be added in properties.dat to turn this action on/off, as follows:

properties.dat

*.notBlockEngServ = false # discard SERVICE messages : default
*.notBlockEngServ = true # pass SERVICE messages through to engine

PropagateSvcMsgBlock Propagation (CSCdp58516)

Propagation of individual SS7 blocking/unblocking messages on systems with large numbers of SS7 bearer channels mated to few NAS signal paths has been noted to cause engine, IO card and switch overload. The changes implemented in this patch control the rate at which BLO/UBL messages may be transmitted so as to avoid overloading any specific part of the system or network.

Specifically, when blocking propagation is turned on in an SS7 Interconnect for Access Servers 2.0 environment (*.PropagateSvcMsgBlock = true), the engine will queue outgoing messages and start sending individual block/unblock messages for all circuits associated with a single span per time interval.

Assumptions:

Blocking propagation (PropagateSvcMsgBlock) is only enabled for SS7 Interconnect for Access Servers 2.0 configurations

Blocking/unblocking messages are always sent for all bearers in a span at the same time

If LOCMAN blocking exists prior to propagation on loss of NAS link, this will be REMOVED when the NAS link is restored. (that is, all channels will be locally unblocked due to propagation of In Service condition)

Queuing of messages is only done for NAS link state change. No attempt will be made to queue individual bearer state changes brought about by reception of SERVICE messages. (See fix for CSCdp70673).

Provisioning:

The time interval and number of spans to send per interval are configurable as follows:

XECfgParm.dat

engine.SysPropagateSpansPerTimer = 1 # number of spans to send per interval
engine.SysPropagateSpansDelay = 500 # milliseconds pause between sending
engine.SysInitialManBlk = true # default CIC state (true = blocked)

properties.dat

*.PropagateSvcMsgBlock = true # perform blocking propagation for TD2.0
*.GRSEnabled = true # send GRS immediately after engine startup

Note Reducing the default interval time interval or increasing the spans/interval count may lead to message loss and engine overload.


Recommended Settings

The following settings were derived during Solution Testing:

Low call volume system (10 cps or less)

Info level: debugging or less

properties.dat:

*.PropagateSvcMsgBlock=true

XECfgParm.dat

engine.SysPropagateSpansPerTimer=1
engine.SysPropagateSpansDelay=500
engine.SysInitialManBlk=true

With these settings, a Netra 1120 should be able to process 10 cps while blocking 15000 circuits over 6:20 minutes with minimal interruption in call processing due to processing of the BLOs from a failure.

High call volume system (<20 cps)

Info level: debugging or less

properties.dat

*.PropagateSvcMsgBlock=true

XECfgParm.dat

engine.SysPropagateSpansPerTimer=1
engine.SysPropagateSpansDelay=800
engine.SysInitialManBlk=true

With these settings, a Netra 1120 should be able to process 20 cps while blocking 15000 circuits over 8:32 minutes with minimal interruption in call processing due to processing of the BLOs from a failure.

Additional information:

The new thresholds value for parameters listed below represent the percentage of engine queue size:

*.Ovl1OnsetThresh = 40

# ovlxOnsetThresh = a percentage of total queue capacity at which

*.Ovl2OnsetThresh = 50

#the overload level will be in effect

*.Ovl3OnsetThresh = 60

 

*.Ovl1AbateThresh = 30

#ovlxAbateThresh = a percentage of total queue capacity at which

*.Ovl2AbateThresh = 35

#the overload level will no longer be in effect

*.Ovl3AbateThresh = 45

#abatement must be less than onset

*.Ovl1RejectPercent = 25

#ovlxRejectPercent = a percentage of new calls that will be rejected

*.Ovl2RejectPercent = 50

#at this overload level. EX: 20% means 1 out of every

*.Ovl3RejectPercent = 100

#five new calls will be rejected at this level


These new sets of overload values need to be implemented to the engine section in the XECfgParm.dat file.

Additional information:

Currently, the ioChanMgr reads the RLM.port property to configure the ISDNIP IOCC. Only one IOCC can bind to the local IP address using the RLM.port. Multiple IOCCs are needed to support the number of d-channels required by customers. If multiple IOCCs are used, the RLM port number must be configurable on a per-IOCC basis. The ioChanMgr changed to read the RLM properties using the IOCC label. If no properties are found prefaced by the IOCC label, ioChanMgr uses RLM as a default. The VSC changes are in properties.dat and sigChanDevIp.dat: (using the IOCC labels from components.dat:; this uses IOCC-PRIIP1, IOCC-PRIIP2, the customer's names and compIds will differ). The configuration must be changed on any NAS that is not configured with 3001 in sigChanDevIp.dat. If you configure the NAS rlm port, it will automatically configure the ISDN port as RLM port + 1. (You can also reconfigure the ISDN port if you want.) Following is an example:

properties.dat:

RLM.port = 3000
IOCC-PRIIP1.port = 3000 (w/compId 30010 )
IOCC-PRIIP2.port = 3002 (w/compId 30011)
IOCC-PRIIP3.port = 3004 (w/compId 30012)
IOCC-PRIIP3.port = 3006 (w/compId 30013)

in sigChanDevIp.dat, change both local and remote ports for 30010 to:

001000xx IP_Addr1 3001 <nas1 ip1> 3001
001000xx IP_Addr2 3001 <nas1 ip2> 3001

for 30011 to:

001000xx IP_Addr1 3003 <nas33 ip1> 3003
001000xx IP_Addr2 3003 <nas33 ip2> 3003

for 30012 to:

001000xx IP_ Addr1 3005 <nas65 ip1> 3005
001000xx IP_Addr2 3005 <nas65 ip2> 3005

for 30013 to:

Installing the ITK Driver

In order to provide enhancements that may impact the resolution of CSCdr48971 bug, it has becomes necessary to build and deliver the ITK Driver package. To install this package, follow these steps:


Step 1 Type the command su

Step 2 Remove the existing ITK driver by typing pkgrm -d ITKP40AA

Step 3 Type Y when prompted

Step 4 Type pkgadd -d ITK-HDLCP40AA.pkg

Step 5 Press Return to accept the default prompt

Step 6 Type Y to install the new patch

The system will reboot automatically after installing the new ITK Driver.

The LED indications on the ITK Card provide comprehensive visual indication of the ITK Card status.

LED
Status
Indication

top

solid green

Layer 1 of the ISDNPRI or SS7 Link terminating into ITK Card is OK

top

solid red

Layer 1 of the ISDNPRI or SS7 Link terminating into ITK Card is broken

bottom

blinking green

Communication Link Between ITK Card and SC2200 software is OK

bottom

blinking red/solid green/solid red

Communication Link Between ITK Card and SC2200 is broken


The blinking rate of the bottom LED is directly proportional to the rate at which the ITK Card processes data. The fix also puts a timestamp on the date the ITK Driver was created. This helps track the version of the ITK software. Use the following command at the UNIX prompt to find out the date:

>modinfo | grep itk

Limitations and Restrictions

The signaling software does not currently support 7-digit dialing in the United States.

General Issues

Addition of Services During System Operation

Release 4.2(19) does not support dynamic reconfiguration during operation (for example, adding new components or making other configuration changes). The application must be shut down to add needed services during routine maintenance.

For instructions on shutting down the telephony controller, see Chapter 3, "Operating Your Telephony Controller," in the Telephony Controller Release 4 Software Operations and Maintenance Guide.

Configuration Tool Client/Browser Session Problems

In release 4.2(19), a configuration tool session that has been inactive for 2 minutes may time out or have other difficulties such as an inability to view existing data. You may also experience problems when resizing your browser window or if the Netscape client hard disk cache is less than 8 MB.

If you experience problems, exit the affected configuration tool session and initiate a new configuration tool session.

The Orbix Web server may experience confusion resulting in a 10191 Orbix not running error message. If this occurs, or if the Orbix daemon fails, stop and restart the system.

Configuration Tool Scroll Bar

The line scroll bar in the configuration tool may lose its position on a list box refresh due to an unresolved situation with the underlying third-party technology.

Configuration Tool Requires Full Host Table Entries When Not Using DNS

On systems that are not using DNS entries or networks where DHCP is being used without DNS entries, you must fully qualify complete host table entries in the C:\winnt\system32\drivers\etc\hosts file as follows:

171.17.193.101 hostname hostname.domain.com

Workaround: Your hosts file on the server must contain the IP address, computer name, and network address of each computer you want to access. For example:

172.29.12.113
your-pc
your-pc.company.com
172.17.192.101
ms-tel1
ms-tel1.company.com
172.17.192.102
ms-tel2
ms-tel2.company.com

Ensure that DNS is enabled on the server (even if you do not have any DNS server entries). Also be sure you give it a host name and domain on the DNS screen. You must have a c:\windows\hosts on your client because you cannot use the IP address as the URL. Then close down the server.bat windows and delete the two files in c:\lightspeed\orbixweb\config\NamingRepository (root and No_0).

Cisco Connection Online

Cisco Connection Online (CCO) is Cisco Systems' primary, real-time support channel. Maintenance customers and partners can self-register on CCO to obtain additional information and services.

Available 24 hours a day, 7 days a week, CCO provides a wealth of standard and value-added services to Cisco's customers and business partners. CCO services include product information, product documentation, software updates, release notes, technical tips, the Bug Navigator, configuration notes, brochures, descriptions of service offerings, and download access to public and authorized files.

CCO serves a wide variety of users through two interfaces that are updated and enhanced simultaneously: a character-based version and a multimedia version that resides on the World Wide Web (WWW). The character-based CCO supports Zmodem, Kermit, Xmodem, FTP, and Internet e-mail, and it is excellent for quick access to information over lower bandwidths. The WWW version of CCO provides richly formatted documents with photographs, figures, graphics, and video, as well as hyperlinks to related information.

You can access CCO in the following ways:

WWW:  http://www.cisco.com

WWW:  http://www-europe.cisco.com

Telnet:  cco.cisco.com

Modem:  From North America, 408 526-8070; from Europe, 33 1 64 46 40 82. Use the following terminal settings: VT100 emulation; databits: 8; parity: none; stop bits: 1; and connection rates up to 28.8 kbps.

Documentation CD-ROM

Cisco documentation and additional literature are available in a CD-ROM package, which ships with your product. The Documentation CD-ROM, part of the Cisco Connection Family, is updated monthly. Therefore, it might be more current than printed documentation. To order additional copies of the Documentation CD-ROM, contact your local sales representative or call customer service. The CD-ROM package is available as a single package or as an annual subscription. You can also access Cisco documentation on the World Wide Web at http://www.cisco.com, http://www-china.cisco.com, or http://www-europe.cisco.com.

If you are reading Cisco product documentation on the World Wide Web, you can submit comments electronically. Click Feedback in the toolbar and select Documentation. After you complete the form, click Submit to send it to Cisco.

You can e-mail your comments to bug-doc@cisco.com.

To submit your comments by mail, for your convenience many documents contain a response card behind the front cover. Otherwise, you can mail your comments to the following address:
