Software Release History
Release 2.4(1) Enhancements
Release 2.4(1) supports Cisco MGC Release 9.4(1) software.
Cisco MNM 9.4(1) adds support for managing the features new in Cisco MGC Release 9.4(1), as shown in Table 1. Enhancement identification numbers are listed where applicable.
Table 1 New Features for Software Release 2.4(1)
Enhancement Identifier Description
Bundles the Provisioning Tool (formerly known as the Voice Services Provisioning Tool or VSPT) for tighter integration.
Adds support for a cluster of Cisco MGC nodes operating in concert with a cluster of two or more Internet Transfer Points (ITPs). In this configuration, one or more ITPs, rather than an SLT, serve as the signaling gateway to the SS7 network. The farm of Cisco PGW hosts appears as a single point code to the Public Switched Telephone Network (PSTN). Supports farm deployment through wizard or seedfile, and related functions.
Change in switch deployment: The LAN switch is no longer deployed under the node object but instead under the MGC-Node-View.
Support for new and modified MML components.
Secure communications (SSH) can be installed on the Cisco PGW, BAMS, and HSI servers, and Cisco MGC Node Manager supports secure communication with these components with an optional CEMF SSH add-in. If you are implementing SSH on the Cisco PGW, BAMS, or HSI servers, you should implement SSH on the Cisco MGC Node Manager by installing the CEMF SSH add-in. This is described in the Installation Guide: http://www.cisco.com/univercd/cc/td/doc/product/access/sc/rel9/emins/index.htm
The seed file value for securityPolicy can be either ssh or none.
Adds support for SGP and Association Performance measurements.

Table 2 lists open caveats for this release.
Release 2.4(1) Resolved Caveats
The following caveats were resolved in this release:
Table 3 Caveats Resolved in Software Release 2.4(1)
Enhancement Identifier Description
Cisco MGC Node Manager now supports VNC.
Problem interpreting IPFAS measurement from PGW.
The following is the minimum hardware and software you need to install and run Cisco MNM:
•Sun Fire 280R (UltraSPARC III) supporting two hard drives in a single rack-mount package; other Sun platforms in the UltraSPARC II and III families are also supported (two CPUs at 440 MHz or faster)
•Sun Solaris 8 operating system
–April 2001 release recommended
–Open Windows with the Common Desktop Environment (CDE)
•2.0 GB of RAM (or greater)
•9 GB SCSI drives properly configured. The database drives should be configured as rawdevices and connected to a separate SCSI controller for maximum performance.
•The tmpfs file system must be mounted to /tmp for maximum performance.
Detailed system requirements are documented in Chapter 1 of the Cisco MGC Node Manager Installation Guide at http://www.cisco.com/univercd/cc/td/doc/product/access/sc/rel9/emins/index.htm.
Review this chapter prior to installing or configuring the software.
Note Installing drives greater than 9 GB does not result in performance gains. The main bottleneck of the CEMF application is hard disk input/output (i/o) speed, not capacity. Maximum performance is achieved using many drives of lower capacity instead of a few, larger capacity drives.
These configurations are supported:
•Cisco MGC Node Manager and Cisco MNM PT installed together on a network management server. (Recommended)
•Cisco MGC Node Manager installed on a network management server and Cisco MNM-PT installed on a Cisco PGW host machine.
•Cisco MGC Node Manager installed on a network management server and Cisco MNM-PT installed on a separate server.
Note Other element managers may be installed on the network management server.
Caution Cisco MGC Node Manager should not be installed on a Cisco PGW 2200 host machine.

Known Issues and Operational Recommendations
This section contains information about known issues and the corresponding workarounds.
Note For more information about Cisco IOS issues and workarounds, see the Cisco IOS release notes for your platform.
Cisco MGC Node Manager Checks for Available Disk Space For Installation
During installation, Cisco MGC Node Manager detects how much disk space is available for installation. If the system does not have enough available disk space, you are prompted whether you want to continue the installation routine. If you enter 'N' to stop the Cisco MGC Node Manager installation, the installation continues.
The workaround is to ensure that enough free disk space is available before Cisco MGC Node Manager is installed. The amount of disk space required is detailed in the Cisco MGC Node Manager installation guide.
Cisco MGC Node Manager Cannot Discover an Interface or IP Address for BAMS
Sometimes Cisco MGC Node Manager reports that it cannot discover an interface or IP address for BAMS. This might be caused by the mib2agt getting into a strange state. You can restart the mib2agt by stopping the current process. The new process mib2agt is restarted automatically.ps -ef | grep mib2agt kill -9 <PID>
Hints and Tips
Initial Cisco MGC Node Manager Configuration
Cisco MGC Node Manager is initially configured with one user:id: admin password: admin
Installing CEMF/Cisco MGC Node Manager on a Server
If you have installed CEMF/Cisco MGC Node Manager on a server and need to change the IP address/hostname, you must make the changes shown in the following procedudre:
Note The following example uses the hostname CMNM and the IP address 10.1.1.1.
Step 1 #cd <CEMF Directory>/bin
Step 2 #./cemf stop
Step 3 Edit /var/adm/Atlantech/system/info to reflect the following hostname and ip address:MGRHOSTNAME=ramblerMGRIPADDRESS=10.1.1.1COREHOSTNAME=rambler
Step 4 Edit <CEMF Directory>/config/env/avCore.sh to reflect the hostname in the lines below, and save the file.MgrSystemManager=rambler1270; export MgrSystemManagerPortAllocator=rambler1270; export PortAllocatortransRouter=rambler1271; export transRouter;
Step 5 Edit /var/sadm/pkg/CSCOcemfm/pkginfo to reflect the following values:MGRIPADDRESS=10.1.1.1MGRHOSTNAME=10.1.1.1COREHOSTNAME=10.1.1.1LOCALHOSTNAME=10.1.1.1
Step 6 You will also need to make these same changes for each Element Manager. To do so, edit the following files:/var/sadm/pkg/hostEM/pkginfo/var/sadm/pkg/mgcEM/pkginfo/var/sadm/pkg/mgxEM/pkginfo
Step 7 Rename <CEMF Directory>/ODI/OS5.1/ostore/<hostname>_server_parameter to reflect the new hostname.
Note You must obtain a new CEMF license. For information on obtaining a new CEMF license, refer to "CEMF Licensing" in the "Troubleshooting" section.
Step 8 <CEMF Direcory>/bin/cemf start
Configuring the CEMF Software for Maximum Performance
The following are guidelines for installing CEMF:
•Use the primary drive for the Solaris operating system and the ObjectStore transaction log.
•The second drive should contain the CEMF software (that is, /opt/cemf).
•Configure the ObjectStore database for Raw FileSystems. The remaining hard drives should contain the RAW FileSystem partitions for the CEMF database (preferably on a separate SCSI controller).
Mount the tmpfs file system to /tmp so the ObjectStore cache files can be kept in memory. ObjectStore is the database program included with CEMF. Keeping the cache files in memory provides for an enormous performance boost for CEMF. Here is how the tmpfs line should read in the /etc/vfstab file (the blank areas between the keywords are spaces):swap - /tmp tmpfs - yes -
Viewing Core Files Generated by CEMF and Cisco MGC Node Manager
Use the /opt/cemf/bin/listCores command to view all core files generated by CEMF and Cisco MGC Node Manager.
If you are having problems with CEMF licensing, you might need to stop and restart the license manager daemon. To do so, execute the following commands:#> /etc/rc2.d/S98alvm stop #> /etc/rc2.d/S98alvm start
Note The CEMF licenses are fixed for a particular machine. You cannot copy the license file from one machine to another. If you want to install the CEMF software on another machine, you must contact Cisco TAC and ask for a new license. You will need the hostname and hostid of the new machine.
Viewing the Most Recently Changed Log Files
Cisco MGC Node Manager log files are stored in <CEMF Directory>/logs. You can view the most recently changed log file with ls -lt command.
Interesting Cisco MGC Node Manager Log Files
Some interesting Cisco MGC Node Manager log files are:
•hostController.log [MGC Host]
•mgcController.log [MGC Node]
•trapLog.log Incoming traps are logged here, to separate them from CEMF log messages collected in mgcTrapProcessor.log.
Error Messages That Are Safe to Ignore
Most of the entries in the Cisco MGC Node Manager log files are created by the CEMF platform and are of limited value. The following error messages are safe to ignore:
•SNMP and MIB parsing errors (which display when an EM controller starts):
–SNMP : ERROR mib.cc:1283 Mib Object is already on the tree for .
–SNMP : ERROR mibDependencyMgr.cc:191 mibDependencyMgr.cc:196 Mib . not defined
–SNMP : ERROR mibParser.y:359 EXPORTS are currently ignored (;, line 8)
–SNMP : WARN mibParser.y:1154 Name and number form OIDs are not properly implemented ().
•Database warning (which display when an EM controller is first installed):
general : WARN Creating Database /opt/AV3/db/mgcController.db
•General errors (which display when the EM controller starts up):
–general : ERROR Unable to get event channel ID for channel ' '
–general : ERROR EventChannelManager : Failed to find location for event channel
–general : WARN OGManager::OGManager - Unable to get deleteEventChannel from .ini file
–general : ERROR OGManager::processGroupClass - invalid class id
–general : ERROR EventChannelManager : Failed to find location for event channel ERROR OGManager::processGroupClass - invalid class id
–general : ERROR OGChangeEventHandler::process - could not find drep!
–general : ERROR IdAllocatorOS : Deprecated constructor called
–Task : WARN PerfPollTask::createGroupsResult : group . already exists.
–mgcController : WARN Controller::initialiseController Controller is configured NOT to auto populate tech tree on autodiscover
•Other misc errors:
–general : WARN CommsBuffer::serialize - resizing buffer size
–general : ERROR PersistentAttributeStore::PersistentAttributeStore() nameInit = 'xxx. is longer than 16 characters. All Objectstore segment comments will be truncated to use the first 16 characters.
Resetting the User Password
If you forget your password, you can reset the CEMF user IDs and passwords. The following command removes all passwords, and resets the admin user ID's password to admin.<CEMF Directory>/bin/cemf shell <CEMF Directory>/bin/partitioningTool -r
Backing Up and Restoring the CEMF/Cisco MGC Node Manager Databases
The following command backs-up the CEMF/Cisco MGC Node Manager databases. By default the backup files are placed in /opt/AVBackup./opt/CSCOcemf/bin/cemf stop /opt/CSCOcemf/bin/cemf backup /opt/CSCOcemf/bin/cemf start
The following command will restore a CEMF/Cisco MGC Node Manager database./opt/CSCOcemf/bin/cemf stop /opt/CSCOcemf/bin/cemf restore -t mm-dd-yyyy /opt/CSCOcemf/bin/cemf start
For more information on backing up and restoring CEMF/Cisco MGC Node Manager Databases refer to the "Cisco EMF Database Backup and Restore Procedures" section of the Installing, Licensing, and Configuring Cisco EMF Manual.
Forcing an Uninstall of an Element Manager
The CEMF daemons must be running for the Element Managers (EMs) to uninstall. There are two ways to force an uninstall of an EM; both cause loss of all CEMF/Cisco MGC Node Manager data. Before running these commands, it is recommended that you back up your databases.
The uninstallCSCOcmnm script can be invoked with an undocumented option to force the removal of all or one EM. From a command line, as root, type the command:
/opt/CSCOcemf/uninstall/uninstallCSCOcmnm -force [-em <EM>]
You can specify only one EM to remove or all EMs by omitting that parameter. The list of EMs includes hostEM, mgcEM, andmgxEM.
/opt/CSCOcemf/uninstall/uninstallCSCOcmnm -force -em mgxEM -em mgcEM
After you run this command, the CEMF databases are corrupted. To correct this problem, reset the CEMF databases by running the following command. You must do this before using CEMF again, even using CEMF to reinstall Cisco MGC Node Manager./opt/CSCOcemf/bin/cemf stop /opt/CSCOcemf/bin/cemf reset /opt/CSCOcemf/bin/cemf start
After you have successfully reset the database and restarted CEMF, you must reinstall Cisco MGC Node Manager. If you want to restore a CEMF/Cisco MGC Node Manager database after you have reinstalled Cisco MGC Node Manager, refer to "Backing up and restoring the CEMF/CMNM Databases" in the preceding section.
If the above method doesn't remove the EMs, then you can try another method. When the EMs are installed, Solaris package information is placed in subdirectories of /var/sadm/pkg. The subdirectory is the name of the packge, as specified above (that is, hostEMm, mgcEMm, and so on.). As the root user, complete the following steps for each EM that you want to remove./opt/CSCOcemf/bin/cemf stop touch /var/sadm/pkg/<EM>/install/.avload pkgrm <EM> /opt/CSCOcemf/bin/cemf reset /opt/CSCOcemf/bin/cemf start
Example:/opt/CSCOcemf/bin/cemf stop touch /var/sadm/pkg/mgcEMm/install/.avload pkgrm mgcEMm /opt/CSCOcemf/bin/cemf reset /opt/CSCOcemf/bin/cemf start
To restore a CEMF/Cisco MGC Node Manager database after you have reinstalled Cisco MGC Node Manager, refer to the preceding "Backing Up and Restoring the CEMF/CMNM Databases".
Managing Network Devices Over a Slow Link
If you are managing network devices over a slow link (T1 or slower), you might need to alter SNMP parameters used by Cisco MGC Node Manager for SNMP Get Requests. You can change these parameters for any existing objects by accessing the States dialog. You can also change these parameters in the Advanced tab of the Seed File Deployment dialog.
The default number of SNMP retries is 2. You might need to increase this value when the Cisco MGC Node Manager workstation is connected to network devices over a slow link.
The default SNMP timeout value is 5000 milliseconds (5 seconds). You may need to increase this value when the Cisco MGC Node Manager workstation is connected to network devices over a slow link.
Maximizing Logfile Output
By default Cisco MGC Node Manager logs only warning and error messages. If you want to turn on debug messages in all log files, complete the following steps, as the root user:
Step 1 cd <CEMF Direcory>/bin
Step 2 ./cemf stop
Step 3 cd <CEMF Direcory>/config/init
Step 4 Edit loggercommon.include and add or change the following line:
loggingLevelMask = 12
Step 5 cd <CEMF Direcory>/bin
Step 6 ./cemf start
Step 7 To set the logging level back to warning, add or change the following line:
loggingLevelMask = 10
