You can use the UserTracking application to update the CWSI database and VMPS server when you have made changes with UserTracking. You can also schedule automatic acquisition of network information.
When you make changes to a screen display table, the changes remain local to the workstation where you are running UserTracking until you send the information on the screen to the CWSI database by clicking the Save button.
To update the CWSI database:
The CWSI database is updated with the data in your screen display table.
If you enter a new MAC address or change an existing one and then update the CWSI database, UserTracking checks to see if the MAC already exists in the database. If the MAC address does not already exist, the MAC address and related fields are added to the CWSI database, provided that the entry also includes a VLAN name and VTP name and that the MAC/VLAN/VTP combination is different from any existing one.
When you download the UserTracking information to VMPS, you send the configuration information stored in the CWSI database to one or more VMPS servers. Because UserTracking is unable to download to a VMPS directly, it uses an intermediate TFTP server. Downloading to a VMPS server therefore requires two steps:
Updating the TFTP servers consists of the following tasks:
To provide login information, you need the username and password for each TFTP server and the name of the directory where the configuration file is stored.
To update the TFTP servers, follow these steps:
Step 1 Select Action>Configure TFTP Servers from the UserTracking main window.
The TFTP Configuration window opens (Figure 5-1). VTP domains for which you might access TFTP and VMPS information are shown in the Select Domain list.
Step 2 Select a VTP domain from the Select Domain list.
The TFTP Servers area displays the IP address or host name and default directory for each TFTP server that provides VMPS information to the selected domain.
Step 3 Take the following steps for each TFTP server you want to update:
(a) Enter the username for the TFTP server in the Login Name field.
(b) Enter the password for the TFTP server in the Login Password One field.
(c) Re-enter the password for verification in the Login Password Two field.
(d) Enter the name of the directory to use for the TFTP file in the Directory field.
Step 4 Click Apply.
UserTracking checks that the password pairs you have entered are identical. If they do not match, an error message is displayed, and you must re-enter the passwords and click Apply again. To discard all the information you have entered in the TFTP Servers area and restore the login information to its state when it was last downloaded or applied, click Restore.
Step 5 Click again on the VTP domain to display the configuration.
Information not generated by UserTracking is displayed in the TFTP Groups and Port Restrictions area. This display includes only the values that you cannot edit in a UserTracking screen display table. It does not include the MAC-VLAN mapping information. If the text area remains blank, there is no information in the configuration file that was generated by anything other than UserTracking.
Step 6 Review and make any needed changes in the displayed configuration file.
Any information you enter will here will be written to the configuration file when you update.
Step 7 Click Apply to save the displayed configuration within UserTracking.
Click Restore to discard all the information you have entered in the TFTP Groups and Port Restrictions area and restore the configuration information to its state when it was last downloaded or applied.
Step 8 Click Download to download the configuration to the TFTP servers in the selected domain.
To update TFTP servers in other VTP domains, repeat Step 2 through Step 8.
Step 9 Click Close.
When you have updated the TFTP servers with the current configuration information, you are ready to update the VMPS servers.
To update the VMPS servers, follow these steps:
Step 1 Select Action>Update VMPS Servers from the UserTracking main window.
The Update VMPS Servers window opens (Figure 5-2).
Step 2 Select the VTP domains in which you want to update VMPS servers.
Step 3 Click Update to update the selected VMPS servers from the TFTP servers.
The configuration file on the TFTP servers updates the VMPS configuration.
Using the UserTracking scheduling feature, you can schedule when UserTracking acquires network information via discovery. You can schedule both full and limited acquisitions.
To schedule when UserTracking discovers network information, take the following steps:
Step 1 Select Action>Acquisition Schedules from the UserTracking main window.
The UserTracking Network Acquisition Schedule window opens (Figure 5-3).
Step 2 Check Perform Minor Acquisition to schedule the frequency of minor network discoveries. If you don't want to schedule minor discoveries, go to Step 4.
A minor acquisition is limited to all IP subnets that are known by ANI to have been active since the last acquisition.
Step 3 Enter a time interval in minutes for the frequency of acquisition.
Step 4 Check Perform Major Acquisition to schedule full network discoveries. If you don't want to schedule major discoveries, go to Step 6.
A major acquisition is a sweep across all IP subnets known to UserTracking. Most of these subnets come from information acquired from switch and router interfaces. If you want to ensure that the switch and router information is current before performing the acquisition, you should enable ping sweeps (see "Using Ping Sweeps with Discovery"). A major acquisition is equivalent to running discovery by selecting Action>Discover>End-User Nodes.
Step 5 Specify a schedule for performing major acquisitions.
You specify a schedule by selecting days, dates, and times to include or exclude from the acquisition schedule. To specify an acquisition schedule, follow these steps:
(a) In the When box, select Every to specify days or dates to always perform major acquisitions, or select Not On to specify days or dates not to perform acquisitions.
(b) In the Day or Date box, select Daily, Weekdays, Day, or Date. Use the popup lists to select a day of the week, or month and date.
(c) In the Time box, use the popup lists to select hour, minute, and AM/PM; select Anytime in combination with the Every option in step (a) when you want to prevent acquisition from being performed at any time on a day or date.
(d) Click Add when you have specified the above items.
You can repeat these steps to configure another time to perform, or a time to exclude from performing, acquisitions. Each time you do this, the scheduling information you have specified appears in the text box.
Step 6 Review the schedule you have made and make any adjustments.
Acquisitions are performed according to the priority in the order of the schedule entries, so the order may make a difference. For example, if you want to schedule daily acquisitions and exclude Sundays, the daily entry should come first, followed by the entry to exclude Sundays. To move an entry up or down, select the entry and click Up or Down. To delete an entry, select the entry and click Delete. You can select multiple, contiguous entries to move or delete.
Step 7 Click Apply to apply your acquisition schedule.
Existing information in routers and switches provides the source for information for UserTracking discovery. To make sure that this information is up to date, UserTracking offers the option of doing a ping sweep, which sends a ping to every IP address in subnets of interest.
You can run UserTracking discovery with or without ping sweeps. If you run the process without ping sweeps, acquisition is made from each router and switch using whatever information is already in their mapping tables. If you run the process with ping sweeps, a ping is sent to every IP address, then the acquisition from the updated tables in the routers and switches is made.
The advantage of using ping sweeps to acquire the most current network information must be weighed against the disadvantage that ping sweeps can degrade the performance of the network.
To enable ping sweeps:
