Settings

The Notifications Settings Definition Screen is used to view and configure Notifications and Trap E-Mail settings. After making a change to one or more of the settings as described below, click on the Apply button. Note that the available display and configuration options depend on user type (e.g., User, System User).

Notification Configuration

• Max No. of Notifications to Store at Server (Read Only) - The maximum number of received traps that can be stored on the OmniVista Cirrus Server. When a trap is received that exceeds the value in this field, the newly-received trap overwrites the oldest trap stored on the server.
• Use OmniVista Trap Absorption (Read Only) - Similar traps received from non-AOS devices during the trap absorption period are "absorbed," and a 'trapAbsorbtionTrap' trap is generated similar to existing AOS traps. This trap contains details, such as the total number of 'sufficiently-similar' traps received since the original trap. For example, if OmniVista receives a 'ChassisTrapsAlert' trap from a switch, OmniVista Cirrus will 'absorb' all of the traps it receives from the same switch that are 'sufficiently similar' to 'ChassisTrapsAlert', until the trap absorption period expires. Note that two traps are considered to be "sufficiently similar" when their names, agent IP address, trap OID, severity, and enterprise OID (if defined) are same, and all their trap variables (if any) are also same.
• Absorption Period (Read Only) - The amount of time, in seconds, OmniVista will "absorb" similar traps. OmniVista extends the trap absorption period when a 'trapAbsorbtionTrap' trap is generated. For example, if a trap absorption period is set to 15 seconds and a 'sufficiently-similar' trap is received on the 8th second, the period for that trap is extended for another 15 seconds. If no 'sufficiently-similar' traps for a trap are received during the trap absorption period, the trap absorption period expires for that trap.
• Receive WIPS Traps - Enables(On)/Disables (Off) receiving traps from the Wireless Intrusion Protection System (WIPS) application.

Trap E-Mail Configuration

The Trap E-Mail configuration fields are used to define the default values for OmniVista "trap responder" e-mails. Trap responder e-mails are e-mails that OmniVista generates automatically when specified traps are received from network devices. The Trap Responder Screen is used to configure OmniVista to send an e-mail when a specified trap is received. (Traps can be specified by severity level, or by use of a filter.) However, to prevent e-mail storms that would result from receipt of multiple traps, OmniVista does NOT send one e-mail per trap received. Rather, OmniVista "combines" responder e-mails to prevent storms. By default, OmniVista will send a "combined" responder e-mail when: one minute has passed since the first trap was received for which an e-mail was not generated, OR 100 traps have been received.

• Maximum Trap Limit - The number of received traps that will trigger a trap responder e-mail. Enter the number of received traps that will trigger a trap responder e-mail.
• Maximum Time Limit - The maximum time period, in seconds, that can elapse before a trap responder e-mail is triggered. The time period begins when a trap is received for which an e-mail was not generated.
