You can use the UserTracking application to acquire network information about end-user nodes, query the CWSI database, and make changes to the entries in the database.
Before using the UserTracking application to query and display information from the CWSI database, you should run the UserTracking discovery process to obtain the most up-to-date network information. When you run UserTracking discovery, ANI queries the agents in switches and routers for information about end-user nodes on the network. UserTracking provides two ways to run discovery:
When you run UserTracking discovery for the entire network, ANI acquires information from switches and routers for all end-user nodes on your network.
To run UserTracking discovery on the entire network:
The discovery process discovers end-user nodes in all VTP domains that are known to ANI and updates the CWSI database. This is equivalent to a major acquisition; see "Scheduling Network Discoveries" in Chapter 5, "Updating Network Information and Scheduling Discoveries."
You can limit UserTracking discovery to a particular subnet. You may want to do this if, for example, you know that changes have been made that affect end-user nodes on a specific subnet.
To discover a subnet, follow these steps:
Step 1 Select Action>Discover>Subnet from the UserTracking main window.
The Discover Subnet window opens (Figure 3-1).
Step 2 In the Host Name or IP Address field, enter the name or IP address of a known end-user node on the subnet you want to discover.
Step 3 Enter the subnet mask for the IP address you specified.
The subnet mask is applied to the IP address to determine the subnet you want to discover.
Step 4 Click Discover.
UserTracking discovery discovers node and user information about the specified subnet and updates the CWSI database.
The UserTracking application provides two ways to display information from the CWSI database:
If you want to display the entries in the database without performing a query, you can do so by using the options under the Action>Display submenu.
To query user information from the CWSI database, you specify one or two query criteria. For example, you may want to find the user of a particular MAC address, or you may want to display all the users on a particular VLAN and subnet. UserTracking responds to your query by displaying the database entries that match your criteria in a screen table. The database contains information gathered through UserTracking discovery or manually entered from the UserTracking application.
To query and display MAC-to-VLAN mapping and related information, follow these steps:
Step 1 In the Query Selector Items box of the UserTracking main window, click on the upper arrow button to display the choice of fields.
Step 2 Select the field that corresponds to the type of information you want to search for. These fields are described in Table 3-1.
Step 3 Enter the first value for your query in the field to the right of the arrow.
A search is successful if the entry contains the search value anywhere in the entry. Searches are case-insensitive. For example, the search value "bank" matches Bank, Interbank, Inter-bank, and BANKERS, but does not match ban-ker.
Step 4 To specify a second query criterion, select a second field to query and enter a value.
If you only want to query one value in one field, leave the second field blank and go to Step 6.
Step 5 Select the And or Or radio button to combine or expand the two query fields.
Step 6 Click Query or select Action>Query.
The results of your query are displayed in the screen display table in the lower part of the main window (Figure 3-2). These results represent the current user information in the CWSI database that matches your query items and include information gathered when UserTracking discovery was last run, as well as any information that has been manually entered using the UserTracking application itself.
You can further customize the table that displays the results of your query by sorting, resizing columns, and designing your own the screen layouts. See "Customizing the Display" in Chapter 4, "Customizing and Saving Screen Display Tables."
Table 3-1 lists the contents of the screen display table and indicates which fields you can modify from the UserTracking interface.
UserTracking provides the option to keep currently displayed data on the screen and add to it the results of a new query.
To append new data to an existing screen display table, follow these steps:
Step 1 Click Append results in the Query Selector Items area of the UserTracking main window.
Step 2 Specify a new query as described in "Constructing a Query."
When you click Query, any new entries that match your query and that are not already displayed are appended to the screen display table. If Append Results is not checked, the currently displayed information is replaced with the results of the new query.
You can locate an entry of interest in the currently displayed table by searching for a string.
To search for a string in the screen display table, follow these steps:
Step 1 Select Edit>Find on Screen.
The Find window opens (Figure 3-3).
Step 2 Enter the string to search for in the Find field.
A value entered in the Find field matches a table entry if the entry contains the search value anywhere in the entry. Searches are case-insensitive.
Step 3 Select Down Columns or Across Rows from the popup menu to specify the direction of the search.
Step 4 Click one of the following buttons to start your search:
Found occurrences of the search string are highlighted in the screen display table.
If you are running UserTracking as a part of CWSI, you can locate and highlight devices on the CWSI network map.
To locate devices on the CWSI map, follow these steps:
Step 1 Select one or more entries in the displayed screen table.
Step 2 Select Action>Highlight Devices on Map.
The selected devices are highlighted on the CWSI network map.
The UserTracking application enables you to add entries to, modify, and delete entries from the screen display tables.
To make changes to an existing screen display table entry, follow these steps:
Step 1 Click to select the cell you want to modify.
Note that you can modify only the following fields:
If you change the MAC address/VLAN name/VTP domain combination such that it matches an existing entry, UserTracking will disallow the change.
Step 2 Enter the new value.
A popup list of available options is displayed when you click in the VLAN and VTP cells. Once you change the value in a cell, it is displayed in boldface type. If you modify a MAC address, UserTracking checks the syntax for correctness.
Step 3 Click Save or select Action>Save to save your changes to the CWSI database.
The CWSI database is updated with all changes and port state is updated on the switch. To update only the port state on the switch, select Action>Update Port State. If you modify only the Notes or User Name fields, only those fields are updated in the database when you click Save.
Before making a new table entry, you should know the MAC address, VLAN name, and VTP domain for the device you want to map. When adding an entry, your changes remain local to UserTracking until you save to the CWSI database.
To add a new entry to the table, follow these steps:
Step 1 Position the cursor in the row below where you want to insert a new row in the screen display table.
Step 2 Select Edit>New Row.
A blank row is inserted into the table above the insertion point.
Step 3 Enter the MAC address for the device you are mapping.
After you enter a value and press Tab or Enter or click in another cell, UserTracking checks the syntax of your entry.
Step 4 Click in the VLAN cell and select from the popup list the VLAN to which you are assigning this device.
Step 5 Click in the VTP Domain cell and select from the popup list the VTP domain for this device.
MAC address, VLAN name, and VTP domain are the minimum items required for a new table entry. UserTracking will disallow an entry in which any of these values is missing. If the MAC address/VLAN name/VTP domain combination already exists, UserTracking will disallow the entry.
You can also enter any notes and a user name of your choice, but you cannot specify values for the remaining fields. For a description of the fields and their formats, see Table 3-1.
Step 6 Click Save or select Action>Save to save the new entry to the CWSI database.
UserTracking allows you to delete entries from the screen display table. Deleting an entry removes it both from the screen display table and from the CWSI database. You can delete a single entry or several at a time.
To delete an entry, follow these steps:
Step 1 Select the row you want to delete by clicking on the tab at the far left of the row.
To select additional contiguous rows, hold down the shift key and click, or drag the cursor over the tabs on the rows you want to select. To select additional non-contiguous rows, hold down the control key and click.
Step 2 Select Edit>Delete Rows.
The selected rows are removed from both the screen display table and the CWSI database.
