Device Reports and Graphs

With the Device Reports and Graphs page, you can:

• Generate device reports.
• Display learned addresses and port configuration information.
• Display port statistics.
• Display bandwidth used on the switch.
• Refresh device report information.
• Access Cisco Visual Switch Manager.

Note: You must enable SNMP and set the community string set to "public" to generate reports.

Generating Device Reports

From the drop-down list, select Config Information, System Information, or Port Information.

• Config Information displays the switch host name, description, location, contact name, member IP address and mask, default gateway, domain name, and the state of Cisco Discovery Protocol (CDP) and Spanning-Tree Protocol (STP). If a member switch has no IP address assigned to it, the IP address of the command switch is displayed.
• System Information displays the system uptime, IOS software version, Cisco Visual Switch Manager (CVSM) software version, image (configuration) filename, NVRAM buffer size, Flash memory space (total and available), address capacity, and bandwidth in use.
• Port Information displays a row of colored buttons that represent ports. You can click a port button to display the MAC address, port name, duplex mode, speed, and administrative status. The port color displays the port status; for example, a green port means the link is up, and a blue port means no link is present.

Displaying Learned Addresses and Port Configuration Information

You can display dynamically learned MAC addresses on a switch port. The switch learns the source address of each packet it receives on each port and adds the address and its port number to the address table. As stations are added or removed from the network, the switch updates the address table, adding new entries and aging (removing) those not in use.

To display the learned addresses for a selected port and other port configuration information:

1. From the drop-down list, select Port Information.
2. Click one of the port buttons on the page.
   If you click a green port button, port configuration information is displayed in the fields on the page.
3. Click List Learned Addresses.
   The list box fills with MAC addresses that were learned by the switch.

Displaying Port Statistics

To generate a graph for the selected port:

1. From the Device Report and Graphs page, click Device Report.
2. Select Port Configuration from the drop-down list.
3. Click the port button and click Graph.
4. In the drop-down list, select one of the graph types: % Utilization, Total Bytes, Total Packets, or Total Errors.
   For more information, review the graph descriptions.
   Note: You can change the graph polling interval by clicking User Settings in any view. To make the new settings take effect, close the graph window. Then in Netscape, click Reload (in Internet Explorer, click Refresh) to reload the page. Reopen the graph window. For more information, click Help on the User Settings page.

Displaying Bandwidth Used on the Switch

The bandwidth graph measures in Mbps the bandwidth used on the switch. The graph provides an estimate of the traffic flowing through the switch.

To generate a graph from the Device Reports and Graphs page, click Graph to see the bandwidth used in Mbps on the selected switch.

Note: You can change the graph polling interval by clicking User Settings in any view. For more information, click Help on the User Settings page.

Refreshing Device Report Information

To refresh device report information, click Device Report.

Accessing Cisco Visual Switch Manager

You can reconfigure the switch from CVSM. Click Switch Manager to display the Cisco Visual Switch Manager Home page in a separate browser window.
