Device Reports and Graphs
With the Device Reports and Graphs page, you can:
Note: You must enable SNMP and set the community string to
"public" to generate reports.
From the drop-down list, select Config Information, System
Information, or Port Information.
- Config Information displays administrative information about the
switch, the state of Cisco Discovery Protocol (CDP), and the state of the Spanning-Tree
Protocol (STP) for VLAN 1. If a member switch has no IP address assigned to it, the IP
address of the command switch is displayed.
Note: The STP state always pertains to VLAN 1, even if you
designate a different VLAN as the management VLAN.
- 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.
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:
- From the drop-down list, select Port Information.
- 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.
- Click List Learned Addresses.
The list box fills with MAC addresses that were learned by the switch.
To generate a graph for the selected port:
- From the Device Report and Graphs page, click Device Report.
- Select Port Configuration from the drop-down list.
- Click the port button and click Graph.
- 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.
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.
To refresh device report information, click Device Report.
You can reconfigure the switch from CVSM. Click Switch Manager to
display the Cisco Visual Switch Manager Home page in a separate browser window.
