Cisco UGM System Requirements
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.

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:

Cisco IOS Compatibility Matrix for Cisco UGM 2.0
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:
•
•
•
•
•
•
•
•
•
•
•
•
•
•
•
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 Scenarios
The following table shows tested deployment scenarios for a single management server with the associated qualifying parameters.
Note
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.

Trap rates and duration3

15 traps per second for 4 hours; 30 traps per second for 30 minutes.
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
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.
About Management Bandwidth
The following table and figure shows the minimum bandwidth requirements for managing a network.
Operating Tips
This section contains the following topics:
•
•
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.
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.
About Commissioning and Decommissioning Devices
To optimize system performance, commission or decommission no more than three devices at a time.
About Reloading Devices
Even though you can perform the Reload operation on multiple devices, do not reload more than three devices at a time.
Since Reload is a scheduled operation, you can schedule up to three devices to be reloaded at time A, then schedule the next group (up to three devices) at time A + 30 minutes, and follow the same sequence with the remaining devices.
Caveats
This section contains the following caveats:
•
•
•
•
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
To resynchronize the internal cache with the database, complete these steps:
Step 1
Step 2
Step 3
Step 4
Step 5
Step 6
Step 7
decommissioned > commissioned > discovering > normal.
Step 8
Step 9
Step 10
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.
2.
3.
This creates a new set of SNMP indices for the device object.
4.
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:
•
•
•
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:
•
•
Workaround
None.
This condition will be fixed in a future Cisco IOS image release.
