Hardware Supported by Cisco EMF
The following table provides guidelines for your Cisco UGM installation. In making system hardware choices, consider your network deployment scenario and also see the "Network Configurations Supported by Cisco UGM" section.
Software Requirements
Cisco IOS Compatibility Matrix
Network Configurations Supported by Cisco UGM
Cisco UGM is designed for flexible operation. With Cisco UGM, you 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.
Note
If you are planning to install more than one network management system on a single server, contact your CSE.
Cisco UGM 1.0 has been tested as a standalone product and may have limitations when installed with other network management systems on the same server.Following is a list of variables that affect the performance and scalability of Cisco UGM:
•
•
•
•
•
•
•
•
•
•
•
•
•
•
There are many permutations for all the variables listed. The following section describes a scenario that was successfully tested and can be used as a guide to size a network domain managed by Cisco UGM.
Network Configuration Scenario
The following table shows a tested deployment scenario for a single management server with the associated qualifying parameters.
Note
For example, 250 fully loaded Cisco AS5800 devices cannot be managed from a single server as this would exceed the 50,000 port limit.
About Excessive Incoming Traps
Excessive incoming traps may adversely affect Cisco UGM performance. If this occurs, evaluate incoming traps and disable those that are unnecessary (as shown in the following examples).
Examples of disabling incoming traps:
interface group-async0
no snmp trap link-statusinterface virtual-template 1
no snmp trap link-statusinterface dialer0
no snmp trap link-statusAbout Management Bandwidth
The following table and figure show the minimum bandwidth requirements for managing a 50,000 port network.
About Renaming Objects in Map Viewer
Cisco UGM allows you to rename objects in Map Viewer. However, the new name cannot contain any spaces. Any spaces in the object name affect system IOS operations.
If you assign an object name with spaces and then attempt to perform any IOS operation such as Get Configuration, Send Configuration, Install IOS Image, Install Modem Image, or Install SPE Image, Cisco UGM displays the following message in the IOS Action Report window:
Cannot connect, please check the user name and password.
Discovery and Deployment Caveats
This section contains information about the discovery and deployment function of Cisco UGM.
Deleting Manually Deployed Device Objects (DDTS:CSCdr48990)
Deleting a site object from the Physical view in Map Viewer does not delete the manually deployed device objects in the site object.
Automatically deployed device objects follow the site object/device object relationship. When you manually deploy device objects Cisco UGM does not create the site object, and device objects are deployed without a site. During normal operation, when you delete a site object, the device objects contained in that site are also deleted.
The following procedure describes how to manually deploy device objects, delete the site in which they are contained, and then verify that the device objects themselves are not deleted.
Step 1
Step 2
Step 3
Step 4
Step 5
Step 6
Step 7
Step 8
The devices in the deleted container object are listed.
Working Around the Condition
Step 1
Step 2
Caution
Device Objects Cannot be Created in Region and Bay Containers
(DDTS: CSCdt68717)If you deploy region and bay containers and attempt to deploy device objects in them, the deployment fails.
Working Around the Condition
Create only site containers and name them to represent different areas of your network.
Tips
Rediscovering Identical Cards in a Chassis (DDTS: CSCdv07469)
When a chassis containing two identical cards is deployed, and you insert a third identical card in a chassis slot, the rediscovery fails. The chassis transitions to an errored state and then a normal state. The internal cache in ASMainCtrl is not synchronized with the database, and Cisco UGM may behave erratically.
Working Around the Condition
If you have more than two cards of the same type installed in a chassis and wish to install a third card, follow these recommendations:
Step 1
Step 2
Step 3
Step 4
Note
Rediscovery Fails to Create New Objects (DDTS: CSCdv19501)
This condition can have several symptoms:
•
The workaround is to delete the device object and deploy it again. This erases all performance and alarm information for this device.
•
Rediscovery recreates the subcomponent objects, but all performance and alarm data for the objects is erased.
To work around this condition, export the performance data to file before changing the dial-shelf Id for the device. (Refer to the Cisco Universal Gateway Manager Users' Guide for details.)
•
The workaround is to always reboot the device in order to allow configuration changes to take effect.
•
There is no workaround for this condition.
Memory Leaks During Deployment and Deletion of Objects (DDTS: CSCdu01611)
During the deployment and deletion of subcomponent objects, memory leaks may occur. The memory loss is proportional to the number of subcomponent objects deployed or deleted. For every object that is either deployed or deleted, an estimated 64 bytes of memory are lost.
A symptom of this condition is the accidental exit (and restart) of the ASMainCtrl controller processes. Database corruption usually results from this condition.
Working Around the Condition
After large deployment operations, when your system is stabilized, stop and start Cisco EMF.
Note
Performance Management Caveats
This section contains information about the performance management function of Cisco UGM.
Correcting the Presentation of Performance Polling MIB Variables
(DDTS: CSCdt35957)To view the relevant MIB fields, follow this procedure:
Step 1
Step 2
Step 3
Step 4
Step 5
Step 6
Memory Poll Name
Memory Pool Name
ciscoPingRceivedPackets
ciscoPingReceivedPackets
Note
Missing Interface Data in Performance Polling File (DDTS: CSCds31288)
With the exception of Ethernet ports, other Cisco UGM-managed ports may not have all their data delivered to the performance data export file. This occurs because all relevant data is not always sent to the Cisco UGM system.
The ifTable in Cisco UGM is polled in order to monitor Ethernet port-related performance data. This data is then stored in the Cisco EMF database. Check the performance data export file to verify that Ethernet port-related information is always stored in the ifTable. However, in some cases other interface port data may be missing.
Note
Changing the Performance Polling ON/OFF Flag on a Powered-Down Device (DDTS: CSCdt30825)
To recreate the condition, follow this procedure:
Step 1
Step 2
Step 3
Step 4
Step 5
The following error message appears:
Nothing changed in the dialog, operation was discarded.
Cisco UGM only polls devices that are in a Normal state. Since the device was powered down, it is no longer Normal, and polling has already stopped on the device.
When you attempt to stop performance polling on the device, the error message conveys that your last action did not impact performance polling which was already stopped for the device.
Working Around the Condition
Note
You can check the current state of the device by following this procedure:
Step 1
Step 2
Step 3
The attribute value of CommonEM-MIB.controllerState is the current state of the device.
Performance Polling the First 500 Rows of Multi-Index Tables
(DDTS: CSCdv19475)When performance polling a large table of data, the poller uses a table chunker to split the table into 500-row chunks. Only the first chunk is retrieved successfully.
Working Around the Condition
You can manually change the related object model file and reset the Cisco EMF system as described:
Step 1
<CEMF_ROOT>/config/objectTypes/x_dASMainEM.types
Step 2
Step 3
Old:
"SNMP:CISCO-MODEM-MGMT-MIB.cmSlotIndex,
SNMP:CISCO-MODEM-MGMT-MIB.cmPortIndex"
New:
"SNMP:CISCO-MODEM-MGMT-MIB.cmPortIndex,
SNMP:CISCO-MODEM-MGMT-MIB.cmSlotIndex"

(This second informational message is redundant.)
Note
File Export Caveat
This section contains information about the file export function of Cisco UGM.
Exiting File Export Properties Window (DDTS: CSCdt29344)
The File Export Properties window exits when the Physical tree is empty. To recreate the condition, follow this procedure:
Step 1
Step 2
Step 3
An Action Report window appears with the message that the inventory data export file is created. The File Export Properties dialog box closes and the following error message appears:
Application Exiting, Connection has been lost to the Cisco EMF Manager platform.
