Setting the Device Manager properties
Device Manager communicates with the Business Policy Switch using Simple Network Management Protocol (SNMP). The software is shipped with default values set for important communication parameters, such as the polling interval, timeout, and retry count. You may want to set the parameters before you open a device to manage.
To set the Device Manager properties:
1Choose Device > Properties.
The Properties dialog box opens (Figure 4).
