Discovering devices on a network

The topology discovery process begins when you supply Optivity Switch Manager with one or more network device seed addresses and the application queries the addresses. The Preferences dialog box specifies the seed address and defines the scope of the discovery process.

To discover a network:

  1. From the Optivity Switch Manager menu bar, choose Edit > Preferences.
    2. The Preferences dialog box opens.
  2. In the Seed Address(es) textbox, type the IP address of one or more devices in the network.
    3. Separate multiple IP addresses with commas.
  3. In the MaxHops textbox, type the maximum number of hops.
  4. Use the Layout slider to indicate whether greater speed or better accuracy is more important.
  5. Select other options in the dialog box to control the appearance of the topology map.
    6. See Preferences dialog box items for a description of the options available.
  6. Click Apply.
  7. Click OK.
  8. From the Optivity Switch Manager menu bar, choose Actions > Discover Map.
    9. The topology map is displayed.

The table below describes the items in the Preferences dialog box.


Section Item Description
Discovery
Seed Address(es)
The IP address(es) of one or more devices that Optivity Switch Manager queries using SNMP to start the discovery process. For a list of supported devices, see Installing Optivity Switch Manager, Release 1.1.0.0.
Note: If the devices you want to monitor and configure are not connected to the same network, you can specify multiple seed addresses, separated by commas. The separate networks do not appear to be connected in the network topology map.
Max Hops
The number of hops, between 1 and 20, that a data packet travels from one router or intermediate point to another in the network. (Default is 5 hops.)
Restrict Discovery
Opens the Restrict Discovery dialog box to restrict device discovery to only the devices in the subnets entered. Refer to Restricting discovery for more information.
Map
Layout
Drag the slider to the right (better) or to the left (faster) to indicate how you want Optivity Switch Manager to lay out devices in the network topology map. Refer to Layout slider for more information.
Show Device by
Determines how a device is identified in the network topology map. The selections are:
  • HostName
  • SysName
  • IP Address (Default)
Trim HostName Domains
Truncates Internet host name domains.
Example: nortelnetworks.com becomes nortelnetworks
Non-highlighted area
Allows you to select an option for viewing inactive devices. The options are:
  • Dimmed-Non-highlighted items are shaded. (Default)
  • Invisible-Removes non-highlighted items from the topology map.
Automatically Save on Exit
If checked, the current network topology map is automatically saved to the default.topo file.
Automatically Relayout after discovery
If checked, the network topology map is adjusted for better viewing as it is loaded in Optivity Switch Manager.
SNMP
Retry Count
The number of times, between 0 and 5, Optivity Switch Manager tries to connect to a device using SNMP. (The default is 1.)
Timeout
The amount of time, between 3 and 10 seconds, Optivity Switch Manager waits before trying to connect to a device again. (The default is 5.)
Max Outstanding Requests
The number of SNMP requests, between 20 and 250, that Optivity Switch Manager maintains as open or outstanding. (The default is 100.)
Trace
If checked, additional SNMP information is written to the Optivity Switch Manager error log, and can provide assistance in troubleshooting.
Note: Selecting Trace could slightly slow down performance as extra information is gathered.
