—
Filters by Topology Groups in the Map. The filter displays the number of Groups displayed in the Map, in parentheses.
For example, Topology Groups (3).
—
Filters by the service running on the device. For example, Cisco CallManager.
Reachable
Filters based on status of the device (reachable).
Unreachable
Filters based on status of the device (unreachable).
—
Filters by the routers.
For example, RSM/MSFC.
Physical
Filters by physical discrepancy; for example, link speed.
—
Filters based on the protocols supported on the devices. For example, IPv6.
STP Inconsistency
Filters based on STP loop, PVID, device, or type inconsistencies.
—
Filters based on the spanning tree details of devices. Selecting the filter will result in a view listing the VLANs applicable to all the switches in the selected switch cloud.
PoE Devices
PoE Capable Devices
Filters based on the Power over Ethernet (PoE) capability of the device. Selecting the filter will highlight the devices that are PoE capable in the displayed network view.
PoE is the ability of the LAN switching infrastructure to provide power over the ethernet copper wire to an endpoint (device). For more details, see http://www.cisco.com/en/US/netsol/ns340/ns394/ns147/ns412/networking_solutions_white_paper09186a00801f4325.shtml
TDR Links
Filters by the TDR enabled links.

Filters based on the devices running VTP.
Low
Filter for highlighting the links that are in the low utilization range.
Medium
Filter for highlighting the links that are in the medium bandwidth utilization range.
High
Filter for highlighting the links that are in the high bandwidth utilization range.
Step 4
•
This requires that all criteria be met to highlight devices on the Network Topology View. Therefore, only those devices supporting active links of the selected type are displayed.
•
This requires that any criteria be met in order to highlight the selection on the Network Topology View. However, for discrepancy filters, selecting multiple options from the same top level filter will assume an AND operation.
•
However, you must complete the Displaying Service Attributes procedure to determine whether the specified Service (or any other Service) is currently active on the application server.

Enabling RMON to Measure Bandwidth Utilization
Bandwidth Utilization is the measure of traffic flowing across a link. Campus Manager highlights bandwidth utilization across links, in the Topology maps. It computes the bandwidth utilization by taking the best estimate of the mean physical layer network utilization on the links, during the sampling time interval.
In Topology Map, Campus Manager can differentiate the links using colors, based on the bandwidth utilized by them. You can customize the filters to display bandwidth utilization.
For more details, see Customizing Bandwidth Utilization Filters.
Note
To compute bandwidth utilization in Campus Manager, you must enable Remote Monitoring (RMON). Enabling RMON depends on two parameters.
Parameters for Computation of Bandwidth Utilization
Enabling RMON depends on the following parameters:
•
•
The default values for Bucket Size and Interval are 10 and 300 respectively. Though the values are non-editable through the user interface of Campus Manager, you can reconfigure these values through command line interface. For more details see Modifying the Parameters.
Campus Manager computes bandwidth utilization only for those devices which have the same parametric values as configured and displayed in the RMON Settings page. The application restricts you to configure the same parametric values on all link ports to avoid the conflicts in computation.
Enabling RMON on Ports
Campus Manager allows you to enable RMON on:
•
•
Campus Manager highlights links in the Topology Map even if the devices are managed by other applications such as DFM, HPOV, or CiscoView.
This topic contains:
•
•
Modifying the Parameters
The default Bucket Size is 10 and the Interval is 300 seconds. Campus Manager does not compute bandwidth utilization for the links whose ports have different Interval values.
You can configure new values for the parameters in the ANIServer.properties file. To reconfigure the values, you must restart the ANI server so that the file takes the new value.
For computing bandwidth utilization, Campus Manager takes only the latest values in the ANIServer.properties file. You must reconfigure the link ports according to the values set in the properties file for Topology Map to highlight the links.
You must reconfigure the parametric values before you enable RMON on ports.
Note
To reconfigure the values:
Step 1
Step 2
Step 3
The maximum value that you can enter for RMON.interval is 3600 seconds (One hour).
Step 4
After modifying the bucket size and interval, enable RMON in devices as explained in Enabling RMON on All Ports in Selected Devices or Enabling RMON on Selected Ports in Selected Devices.
You can use RMON.percentageTolerance property in the ANIServer.properties file to provide a value for the Interval in a range. This is a hidden property that creates a range for the Interval value.
The property adds a value to the current Interval forming the upper limit and subtracts a value from the current Interval forming the lower limit of the range. The default hidden value is 10 percent of the Interval.
For example, if the value provided in the ANIServer.properties file is 300, the range will be 270-330. Thus, the samples are collected between the range of 270 to 330 seconds.
If you want to change this default value, you must:
Step 1
Step 2
Step 3
Step 4
Step 5
Step 6
Enabling RMON on All Ports in Selected Devices
To enable RMON on all ports in selected devices:
Step 1
The Enable RMON dialog box appears. The Device Selector pane displays a list of all devices.
Step 2
The RMON Settings area displays the default Bucket Size required as 10; and the Interval in seconds as 300.
For a Bucket Size of 10, and interval of 300 seconds, Campus Manager collects 10 samples of bandwidth utilization across links over a period of 50 minutes, with an interval of 5 minutes (300 seconds).
To modify the Bucket Size and Interval, see Modifying the Parameters. If you modify the parameters, repeat all the steps listed in this section, for enabling RMON with the new parameters.
Step 3
Step 4
The following command is configured on the selected ports:
rmon collection history integer owner ownername buckets bucket-number interval seconds
Example:
rmon collection history 4 owner campusmanager buckets 10 interval 300
Enabling RMON on Selected Ports in Selected Devices
To enable RMON on selected ports in selected devices:
Step 1
The Enable RMON dialog box appears. The Device Selector pane displays the list of devices.
Step 2
The RMON Settings area displays the default Bucket Size required as 10; and the Interval in seconds as 300.
For a Bucket Size of 10, and interval of 300 seconds, Campus Manager collects 10 samples of bandwidth utilization across links over a period of 50 minutes, with an interval of 300 seconds (5 minutes).
To modify the Bucket Size and Interval, see Modifying the Parameters. If you modify the parameters, repeat all the steps listed in this section, for enabling RMON with the new parameters.
Step 3

Time Domain Reflectometry Reports
Time Domain Reflectometry (TDR) is used to detect faults in a cable. TDR checks and locates open circuits, short circuits, sharp bends, crimps, kinks, impedance mismatches, and other such defects.
Time Domain Reflectometry is required when the application cannot establish a link, or if the link does not perform as expected.
This usually occurs if you:
•
•
•
In such cases, the nature of the defect in the cables are important. To detect the defects, you can perform a TDR test on the link. The TDR test checks the various aspects of the performance of physical links and its reliability, and reports status and failure.
This topic contains:
•
•
Understanding Time Domain Reflectometry
Time Domain Reflectometry detects the defects by sending a signal through a cable, and reflecting it from the end of the cable. Open circuits, short circuits, sharp bends and other defects in the cable, reflects the signal back, at different amplitudes, depending on the severity of the defect.
The TDR measures the time taken by the signal to reflect back and thus calculates the distance to the defect in the cable. When the signal reaches the end of the cable, it reflects at a very low amplitude.
Using Time Domain Reflectometry Reports
Campus Manager supports TDR Cable Diagnostic Test and generates a report listing the results of the test on Cisco Catalyst 6000 switches.

Topology Groups
The Topology Groups feature in Campus Manager allows you to create customized views, of the network, in which devices are grouped according to various criteria. A view may be considered as a group of devices or device elements.
You can define the criteria (called a rule) that will determine the settings of your custom view. The rule will determine the group of devices to be displayed in the view.
These groups are subsets of Layer 2 maps, the members being defined by a set of rule expressions. In a network with a large number of devices, a Topology Group helps you to perform operations in a subset of the large network.
You can use Topology Groups Administration to manage the Topology Groups in your system.
The following topics provide information about:
•
Understanding Topology Groups
A Topology Group can be thought of as a convenience view that allows you to view a subset of the entire network based on the group rule defined while creating the view.
These views, which are subsets of the Layer 2 views, can be accessed by a user or a set of users. These custom views are generated using a Campus Manager feature called Grouping Services, which helps manage groups of devices.
Grouping Services determines the membership of a group by interpreting and applying the rule associated with the group.
Hence, Topology Groups provides multiple benefits:
•
•
•
See the following sections for a better understanding of Topology Groups concepts:

Supported Protocols
The following concepts are important for understanding how to use Topology Services:
•
You must make sure that the applicable protocols are implemented correctly in your network; otherwise, the information gathered might be incomplete.
Inter-Switch Link (ISL) Protocol
Inter-Switch Link (ISL) is a Cisco-proprietary protocol that allows VLAN trunking by maintaining VLAN information as traffic flows between switches and routers.
You can pass VLAN information between devices by configuring links between the switches. If you want a link to carry more than one VLAN, you must use ISL. To use ISL, you must configure the ports on both sides of the link as trunk ports.
When two VTP domains are interconnected using an ISL trunk between two LAN switches, by default, no VLAN traffic is forwarded. However, you can configure the ports on each switch to receive and forward specific VLANs.
To configure the ports, the VLANs on either side of the ISL trunk must be identical and share the same VLAN characteristics such as VLAN names, VLAN indexes, and so on.
IEEE 802.1Q
IEEE 802.1Q is the industry-standard for trunking. A standard for encapsulation protocol to carry traffic for multiple VLANs over a single link. You can use this standard when you want to interconnect a Cisco device with a trunk link to a non-Cisco device.
You can use the encapsulation dot1q command on Cisco IOS version 12.0.1(t) or higher for the Cisco routers.
Troubleshooting Topology Services
To troubleshoot Topology Services, see Troubleshooting Time Domain Reflectometry Reports
Troubleshooting Time Domain Reflectometry Reports
Time Domain Reflectometry (TDR) report does not display the entries, and provides a blank report when you run TDR Cable Diagnostic Test on devices, which support TDR.
This occurs even when Campus Manager supports the CISCO-CABLE-DIAG-MIB, and if the read and write community strings are correct. For more details on running TDR test on devices, see Running TDR Test for a Link.
When the TDR test fails, an error message appears:
Unable to get TDR related information from one or more devices.Probable CauseOne or more devices:-May not support TDR-May be Unreachable-have incorrect read/write credentials in DCRRecommended ActionDo the following:1. Enter correct credentials in DCR.2. Initiate Data Collection for the devices.3. Run TDR report.In the log file for Data Collection, you can find the error message:
ERROR: Unable to get Running Status of TDR Test.Probable Cause: Time Taken to complete the TDR test in the device takes long time/Mib support is not available/ Device is not SNMP reachableAction : Add the property TDRTestTimeout and set value for the property in ANIServer.properties to value greater than 7000 and restart ANIServer process.Check SNMP reachability/Check TDR Support on the deviceTo view the log file for Data Collection, go to:
•
•
Probable Cause
When you run TDR Cable Diagnostic Test from Campus Manager, the report generation might take longer. The default time value set for generating the report is seven seconds. Hence, when TDR test takes more than seven seconds, the process times out and Campus Manager does not generate the report.
Possible Solution
When the TDR report does not generate data, you must modify the ANIServer.properties file. To modify the file, you must:
Step 1
Enter pdterm ANIServer at the command line to stop the ANI server.
Step 2
Step 3
Step 4
Enter pdexec ANIServer at the command line to start the ANI server.
