Description
|
Application
|
Provides the ability to see which applications are consuming network bandwidth, and reports on the number of packets and bytes for each application protocol.
|

|
Provides an analysis of the traffic for each specific host. These reports display data on the host IP address, in/out packets, in/out bytes, and non-unicast, broadcast, and multicast packets collected.
|

|
Displays data on the conversation traffic between various sources and destinations. Information displayed includes source IP address, destination IP address, packets and bytes.
|
DSCP Group
|
Displays data on specific encoded information related to how packets traverse the network. These reports display data on the Aggregation Group, in/out packets, in/out bytes, application protocols, and host IP addresses.
|
Switch/Router
|
Displays the port name, bytes, packets, broadcast packets, multicast packets, link utilization, and errors collected for switches and routers.
|
VLANs
|
Displays data on the VLAN ID, errors, packets, bytes, non-unicast packets, and non-unicast bytes collected.
|
General Report Formats
All reports contain hyperlinks, which allow drill-down to related reports. For example, the Applications Report contains protocol names as hyperlinks, which jump to the Application Details Report when clicked. Information about using drill-down links is available in both the Monitor and Reports chapters of this guide.
Additionally, tabular reports contain blue "T" and "R" hyperlinks in each table row. These links are used to open the Trend report and Real-Time Chart, respectively, for individual sources, such as protocols or hosts. Information about using Trend reports and Real-Time Charts is available in the Monitor and Reports chapters of this guide.
Finally, column header names in Cisco PVM reports contain sorting arrows that display a new window with data sorted in either ascending or descending order (see Figure B-1).
Figure B-1 Sorting Arrows
Sample Report Views
Report data can be viewed in different ways.
•Current Rates—Displays the statistics collected over the selected time period.
•Cumulative Rates—Displays the statistics collected for the selected report element since the collection was created or within the selected time period.
•TopN—Displays the data collected for the TopN selected report elements, such as Hosts, VLANs, or Hosts, over the selected time period.
The following figures show samples of the Cumulative Rates (Figure B-2), Current Rates (Figure B-3), and TopN (Figure B-4) report views for the Monitor - Applications report.
Note The value of N in TopN reports is configured, under Setup > Preferences, to values from 1—15. See Editing Preferences, page 2-50 for information on configuring the system-wide value of N for all TopN reports.

DSCP Group
The Differentiated Services Code Point (DSCP) suite reports on specific encoded information related to how a packet traverses the network. DSCP monitoring allows you to validate and fine-tune planning and Quality of Service (QoS) allocations.
DSCP reports are based on the data obtained from the DSMON MIB, which is an extension of RMON-2 that looks into the IP header of every packet to identify the code point that defines how that packet should be handled by DiffServ-enabled devices. DSMON MIB allows creation of DSCP counter aggregation profiles for up to 64 values that can be grouped for aggregation. Each DSCP value may be given a different treatment by a forwarding device, affecting which packets get dropped or delayed during periods of network congestion. The DSCP reports show traffic information for the various configured DSCP aggregation groups.
Aggregation Profiles
By monitoring DSCP bits, throughput for different services can be determined. The DSMON MIB allows different DSCP values to be aggregated into aggregation groups, and associates these groups with aggregation profiles for the following reasons:
•To reduce the number of DSCP counters to monitor.
•Some DSCP values may never be used in a network.
•Different DSCP values may have similar packet treatments.
•To reduce the network management station polling data.
Cisco PVM aggregates the DSCP statistics collected from multiple NAMs. For reporting purposes, Cisco PVM assigns each DSCP profile a unique ID in the database. The system distinguishes one profile from another by examining the definition of each profile. Cisco PVM treats profile definitions as follows:
•If two profiles have the same name but differing DSCP groups, the system will assign a new ID to one of the groups, the data will be aggregated separately, and the groups will appear as two different profiles in the reports.
•If two profiles have the same definition but differing names, the system ignores the name of the new profile and aggregates the newly collected data along with other data belonging to the previously existing profile.
In each case, the system sends an alert that Administrators can view under the Cisco PVM Alerts tab.
Note Aggregation profiles and groups are configured and named in the NAM Traffic Analyzer, external to Cisco PVM.
The DSCP Group suite contains the following reports:
•DSCP Report
•DSCP Applications Report
•DSCP Hosts Report

The DSCP Report (Figure B-11) provides details on the Aggregation Index and traffic.
