MAC Address Summary Reporting

The MAC Address Summary report provides a survey of the complement of MACs in the switched network for the defined date range.

Two primary categories comprise the count: Infrastructure and End Station. NetMRI counts End Station MAC addresses by studying the ARP tables or forwarding tables of other networking devices. These end stations count towards the total count.

Port Saturation Summary Reporting

The Port Saturation Summary report analyzes the consumption and usage of ports during a specified time period. It answers such questions as:

"Am I running out of ports?" (port consumption)

"How many ports are available and how many are used?" (port allocation)

"How heavily are ports being used?" (port usage)

"Which switches are underused?" (top N)

"How are ports being used?" (port usage detail)

The Port Saturation Snapshot report displays port consumption and usage for a specific day. It answers such questions as:

"How many ports are available and how many are used?" (port allocation)

"Which switches are underused?" (top N)

"How are ports being used?" (port usage detail)

1. In the Report Gallery tab, hover over the Port Saturation report you want to run.
2. Under the report's thumbnail, click the Run link. The Run Report Wizard opens.
3. Specify the device group(s) to be covered by the report:
4. In the Device Groups list, double-click the group name (or click the group, then click the button).

   Or: click the Clear button to remove all groups from the Selected Device Groups list.
6. Click Next.
7. Specify the Date to be covered by the report (or for the Port Saturation Summary report, the last day of the period covered by the report).

8. (For the Port Saturation Summary report only:) Specify the Period, Interval and Time Window for the report.

   Note

   If you select a date or period that starts before the maximum data retention date (default is 90 days), the report will not show data for the time before the maximum data retention date.

9. In the Top N list, select the number of underused ports to be listed in the report.

10. In the Interface Groups list, click, SHIFT+click or CTRL+click to select the groups to be covered by the report.

11. Click Run.

To run Report Scheduling, do the following:

1. In the Report Gallery tab, hover over the Port Saturation report you want to schedule.
2. Under the report's thumbnail, click the Schedule link. The Report Scheduling Wizard opens.
3. Specify the device group(s) to be covered by the report:
4. To select a group: In the Device Groups list, double-click the group name (or click the group, then click the button).
5. To deselect a group: In the Selected Device Groups list, double-click the group name. Or: click the Clear button to remove all groups from the Selected Device Groups list.
6. Click Next.
7. Specify the Date to be covered by the report (or for the Port Saturation Summary report, the last day of the period covered by the report).
8. Port Saturation Summary report only: Specify the Period, Interval and Time Window for the report.
9. In the Top N list, select the number of ports to be covered by the report.
10. In the Interface Groups list, click, SHIFT+click or CTRL+click to select the groups to be covered by the report.
11. Deactivate the Hide Neighbor Details option (this will increase the time required to generate the report).
12. Click Run. Step 3 of the Wizard appears.
13. Change the Report Name as needed.
14. The To Emails field is pre-populated with your default e-mail address. If needed, you can replace this with another e-mail address. You can also specify multiple e-mail addresses (separated with commas).

19. If the specifications are correct, click Schedule. The job is listed in the Scheduled Reports tab.

Port Saturation Report Definitions

For Port Saturation report definitions, data collected during a reporting time window is displayed as a single bar in the Port Saturation Summary report graphs. You can filter data in the time window by criteria such as business hours, off-hours, etc.

Port: A port is included in the Port Saturation Report if it meets the following criteria:

The device containing the port is a Switch or Switch-Router, and

The port supports Ethernet (i.e., serial ports are not included), and

The port is not a VLAN port, and

The port is not a trunk port.

Port Availability: A port is available (unused) if it has zero neighbors (usually corresponding to no bar in a graph) for the reporting time window.

% Available: The ratio of Available Ports to Total Ports for the reporting time window.

Port Consumption: A port is consumed (used) if it has one or more neighbors at any time during the reporting time window.

% Consumed: The ratio of Consumed Ports to Total Ports for the reporting time window.

Device Usage: The average of all port usages for those ports meeting criteria for port inclusion and belonging to the device during the reporting time window.
