Traffix Manager provides wizards to help you add and edit event rules.
Refining Event Rules When you add or edit an event rule, you can modify it to monitor the
traffic on your network and your network security, according to your own
requirements.
Specifying Devices
You can specify the groups and devices to which an event rule applies. If
a group is specified, the rule applies to all devices in that group, unless
you specifically exclude a device from the group. The list of devices which
you are monitoring through all these rules is therefore dynamic and may
change if the devices in the group change.
By default, the grouping used for a rule is that currently applied in the
Map. However, once created, a rule always uses the same grouping.
Selecting Protocols
Typically an event rule applies to all traffic, regardless of the kind of
protocol being used. You can restrict the scope of a rule by choosing a
specific application or favorite (set of protocols) for a rule to monitor.
Traffic of other protocol types is then ignored. See
Chapter 4 , “Grouping
Network Devices in the Map” for more information about setting up
applications and favorites.
You can select a predefined protocol, or make your own protocol
selection. See
“User-defined Protocols” on page 62 for more information.
