About Cisco EMF Service Pack 4

The Service Pack 4 upgrade has been certified for use with Cisco UGM 2.1 and includes all Cisco EMF patches made available in earlier service packs. For information on Service Pack 4 features and improvements, refer to the Release Notes for the Cisco Element Management Framework v3.2 Service Pack 4 Cisco Element Manager November 2002 Upgrade located at:

http://www.cisco.com/en/US/products/sw/netmgtsw/ps829/products_release_and_installation_notes_chapter09186a008010b5cb.html

Resource Manager Essentials

Service Pack 4 includes the Resource Manager Essentials (RME) feature that can be optionally installed. For more information on RME, refer to this URL:

http://www.cisco.com/en/US/products/sw/cscowork/ps2073/index.html


NoteInstall RME on a separate server from that on which Cisco UGM 2.1 is installed. For system requirements, refer to the Release Notes for the Cisco Element Management Framework v3.2 Service Pack 4 Cisco Element Manager November 2002 Upgrade.

RME does not currently provide software image management support for the Cisco AS5850 Universal Gateway. However, all other RME functions are supported for the Cisco AS5850 device.


About Solaris 2.6 Patches for Operating Cisco UGM 2.1

After installation, Cisco UGM sometimes fails to create objects in the NAS-File-Repository tree. If your Map Viewer shows this condition, check the IOSConfigCtrl.log file for this error message:

IOSConfigMgr::getConfigVersionObjectContents: Could not open the filename file for reading

Where:

filename is similar to <CEMF_ROOT>/config/IOSConfigCtrl/IOSFiles/EnableT38

<CEMF_ROOT>is the directory (usually /opt/cemf) where you installed Cisco EMF


Tip During installation, the EnableT38 configlet is the first file that Cisco UGM attempts to read.


To rectify this condition, install one of these:

Solaris 2.6 patch 101242-11 or later patches

Solaris 2.6 patch 105591

You can download these patches from either of these locations:

Network Configurations Supported by Cisco UGM

Cisco UGM is designed for flexible operation. With Cisco UGM, you can select how often data is polled from the network and where SNMP traps will be forwarded. Performance, scalability, and the number of ports and devices managed all depend on your choices.

The following list describes some variables that affect the performance and scalability of Cisco UGM:

Type and configuration of the server hardware where Cisco UGM is deployed (see the "Cisco UGM System Requirements" section)

MIBs that are polled

Polling frequency for polled objects

Mix of objects polled

Presence polling frequency

Number of concurrent active Cisco UGM clients

Activities performed by the concurrent active Cisco UGM clients (including discovery, viewing performance data, and viewing near real-time displays)

Number and type of Cisco Access Servers in the network

Number of ports in the network

Management bandwidth between the managed device and the Cisco UGM server

Management bandwidth between the Cisco UGM server and client

Volume of event traffic received by Cisco UGM (steady state and burst traffic)

Volume of SNMP event traffic forwarded by Cisco UGM

Volume, storage duration, and frequency of inventory, fault, and performance data exported by Cisco UGM

Uploads and downloads of IOS images, firmware images, and configuration files.

There are many permutations for all the variables listed. The following section describes a scenario that was successfully tested. You can use this scenario as a guide to size a network domain managed by Cisco UGM.

Network Configuration Scenarios

The following table shows tested deployment scenarios for a single management server with the associated qualifying parameters.


Note Performance testing for Cisco UGM 2.1 is ongoing. This release note will be updated as additional test results become available.


Cisco UGM manages high-density systems such as multi-DS3 Cisco AS5800 devices and low-density systems such as 2 x PRI Cisco AS5350 devices. Depending on the mix of devices in your network, different ceilings will be reached for the maximum supported network size. For example, if you have Cisco UGM installed on a Sun Ultra 60 server, you cannot manage 60 Cisco AS5850 devices each with a 2 x CT3 configuration. This would exceed the 75,000 port limit.

1 Option 1 system requirements are described in the "Cisco UGM System Requirements" section.

2 Option 2 system requirements are described in the "Cisco UGM System Requirements" section.

3 These trap rates were maintained for the entire duration of the test. The duration of each test scenario was 96 hours or more.



Note If you are already managing more than 50,000 ports and wish to deploy additional devices, Cisco recommends that you first suspend all performance polling activities on the Cisco UGM server.

The number of ports already managed added to the number of additional ports to be deployed should not exceed the number of ports specified in the table.

Operating Tips

This section contains the following topics:

About Deleting Device Component Objects

About the Event Browser

About Deleting Device Component Objects

The number of device component objects that you can delete at a time depends on the load and activities on your system.

If your network contains 60,000 ports and operates with a load and activities as described in the "Network Configuration Scenarios" section, you can delete up to 2,000 ports at a time.


Tip If you attempt to delete more than 2,000 ports, the Deletion Wizard window may freeze; then, you may have to stop and restart Cisco EMF.


About the Event Browser

Open the Event Browser window before you start performance polling operations. If Cisco UGM has started processing traps, the volume of traps may delay the Event Browser window from opening.

Once the window is open, it is updated in real time.

Caveats

This section contains the following caveats:

Manual Deletion of Device Component Objects Does Not Update Cache (CSCdt57107)

Rediscovery Causes Unnecessary Object Creation and Loss Of Performance Data (CSCdv65454)

CISCO-POP-MGMT-MIB cpmDS0UsageTable does not Contain DS0 Data (CSCdy29558)

RFC1406-MIB dsx1ConfigTable and dsx1CurrentTable do not Contain Data (CSCdx94617)

Manual Deletion of Device Component Objects Does Not Update Cache (CSCdt57107)

Symptom

Manual deletion of device component objects is not detected by the deployment code, and the internal cache is not synchronized with the database. Any operations that use the cache are now unpredictable as they attempt to manipulate non-existent objects. This could result in database corruption including the deletion of objects in ASMainEMSConfig.

Workaround


Caution Do not alter the device component hierarchy by reparenting, renaming, and deleting objects.

To resynchronize the internal cache with the database, complete these steps:


Step 1 To decommission the device in order to start rediscovery choose AS5xxx object> Chassis > Chassis Commissioning.

Step 2 Click Decommission.

Step 3 To decommission and commission the device to trigger a transition into the discovering state, choose AS5xxx object> Chassis > Chassis Commissioning.

Step 4 Click Decommission.

Step 5 Choose AS5xxx object> Chassis > Chassis Commissioning.

Step 6 Click Commission.

Step 7 Check for the state transitions:

decommissioned > commissioned > discovering > normal.

Step 8 Repeat Step 3 through Step 7.

Step 9 Delete the device object and rediscover it.

Step 10 Stop and restart Cisco EMF.


Rediscovery Causes Unnecessary Object Creation and Loss Of Performance Data (CSCdv65454)

Symptom of Unnecessary Object Creation

This condition is seen when this sequence of events occurs:

1. Configuration changes are made to a device object without reloading it.

2. Cisco UGM rediscovers the device and its components.

3. The device is reloaded.

This creates a new set of SNMP indices for the device object.

4. Cisco UGM recreates device and component objects.

The newly created objects operate normally.

Workaround

None.

Symptom of Loss of Performance Data

Universal ports and modems are usually identified by slot number and port number. However, Cisco AS5800 devices also include the dial-shelf-id in this identifier.

Since a configuration change alters the dial-shelf-id, the universal ports and modems on the device get new identifiers as well. Cisco UGM detects the parent device as being new, deletes all the device components, and proceeds to recreate the objects. Performance and alarm data for this device object are lost.

Workaround

Before making configuration changes, export data to file. (In the Map Viewer, choose ASEMSConfig > File Export > Open File Export Properties.)

CISCO-POP-MGMT-MIB cpmDS0UsageTable does not Contain DS0 Data (CSCdy29558)

Symptom

When a managed device, its E1 trunk card, and E1 ports are discovered, no DS0 objects are shown under the port. This condition is seen on the Cisco AS5300, AS5350, AS5400, AS5800, and AS5850 platforms when these requisites are present:

The managed device is running Cisco IOS image 12.2(11)T

The managed device has an E1 trunk card installed

The E1 port in the trunk card is configured as ds0-group

Workaround

None.

This condition will be fixed in a future Cisco IOS image release.

RFC1406-MIB dsx1ConfigTable and dsx1CurrentTable do not Contain Data (CSCdx94617)

Symptom

When the Cisco AS5300 managed device and its T1 or E1 trunk card are discovered, no T1 or E1 ports are shown under the card. This condition is seen when these requisites are present:

The managed device is running Cisco IOS image 12.2(11)T

The managed device has a T1 or E1 trunk card installed

Workaround

None.

This condition will be fixed in a future Cisco IOS image release.
