Using Protocol Zoom

Protocol Zoom lets you see protocol information that is collected by a specific agent in more detail.

The following sections contain information about working with Protocol Zoom:

Before using Protocol Zoom, you would typically first use a multisegment, multidomain tool (such as the Protocol Monitor application) to get a basic idea of which segment of your network you want to monitor, then use the single-agent, multidomain Protocol Zoom application to examine that segment more closely. With Protocol Zoom, you can see how different components within a protocol family (children and grandchildren) are being used on a selected segment.

Protocol Zoom lets you change how the protocol information is displayed (for example, pie chart or 2-D bar chart), but you cannot change any of the information in the display. You can also start other applications directly from Protocol Zoom, making it easier to monitor your network.

Note To begin working with Protocol Zoom, you must be logged into the TrafficDirector application, and the main window must be open.

Starting Protocol Zoom

To start Protocol Zoom, follow these steps:

Step 1 From the TrafficDirector main window, click the Protocol radio button.

Step 2 Click the Agent, Switch, or Frame Relay radio button.

Step 3 Do one of the following:

If you selected Agent, select an agent name in the list box.
If you selected Switch, select a switch name in the switch list box. Select a switch port name in the interface list box (lower left of screen).
If you selected Frame Relay, select a Frame Relay agent name in the Frame Relay list box. If necessary, select a DLCI interface in the interface list box (lower left of screen).

Step 4 Select a Domain Name from the list under the Domain Name heading.

If you do not select a domain name, the default domain RMON is used.

Step 5 Click the Protocol Zoom icon.

The Protocol Zoom window opens (Figure 23-1).

Working With the Protocol Zoom Window

The Protocol Zoom window provides two separate but related displays:

Children area---Displays selected statistics for the children of the domain (protocol) for which Protocol Zoom was started (children of the parent domain).
Grandchildren area---Displays selected statistics in terms of the children of the protocols displayed in the children area (grandchildren of the parent domain).

By default, information displayed in the Grandchildren display corresponds to the first protocol on the graph in the Children display. To view information in the Grandchildren display for a different protocol, click the box to the left of the protocol name, or click directly on the graph. The Grandchildren display will refresh to show the Grandchildren that correspond to the selected protocol. If Grandchildren are not defined for a particular protocol, the following message is displayed:

Changing the Protocol Zoom Display Options

By default, the Protocol Zoom window displays the utilization and the agent name; however, other display options are available. To select a different viewing option, select an option from the View menu.

Table 23-1 describes the Protocol Zoom viewing options.

Changing Protocol Zoom Format Options

By default, the Protocol Zoom window displays a 3-D vertical bar graph; however, you can change the format of the information displayed. When you select a format option, the graph changes to display the information differently. To select a format option, select an option from the Format menu.

Table 23-2 describes the Protocol Zoom format options.
