Network Management as a Service

Notifications Home

The Notifications Home Screen displays configured traps received from network devices and provides basic trap information (e.g., severity level, date/time received). Click on a trap to display detailed trap information. You can also use this screen to acknowledge/delete specific traps, quickly acknowledge/delete all traps in the Notifications Table, or poll devices for traps.

Viewing Traps

By default, all traps from all devices are displayed in the Notifications Table. However, you can use the filter function to customize the display. Select one or more options from the "Filters" drop-down menus and select search criteria.

Filter By - Select which devices you want to view.
- All - Select "All" to display configured traps from all network devices.
- Map - Select "Map" and select a map(s) to display traps from only the devices contained in the selected map(s).
- Device - Select "Device", select Switch Picker or Topology in the "Select Using" drop-down, then click EDIT in the "Devices Selected" field to view traps from specific devices. You can also select "Quick Select" and select a device(s) from the drop-down menu.
- AP Group - Select "AP Group" and select a group(s) from the drop-down to display traps from a specific AP Group(s).
- NMS Level - Select "NMS Level" to display traps received from the Wireless Intrusion Protection System (WIPS) application.
Trap Names - Enter a trap name to search for a specific trap. To search for multiple traps, enter each trap name separated by a comma, with no space after the comma. (e.g., alasnmptrapup, alasnmptrapdown).
Severity - Select the Severity Level(s) of the traps you want to display: Critical, Major, Minor, Warning, Normal. You can select multiple Severity Levels by clicking on each level and then clicking anywhere outside the field box. De-select a previously-selected level by clicking on it. You can also select all levels by clicking on "Select All at the top of the drop-down menu). If you select "Remove All" levels, all traps are displayed, regardless of Severity Level ("0 Selected" - Default).
Acknowledged - Select whether you want to view all traps (Any), Acknowledged Traps (True), or traps that have not been acknowledged (False).
Time Range - By default, the most recent traps are displayed (Most Recent). To display traps from a specific time range, select the "Custom" radio button and enter the time range.

After setting the view criteria as described above, the table will be filtered based on selected criteria. Click on the X in the right corner of the Filter Configuration window to close the window.

You can also use the "search" function to further filter the current Notifications Table display. Enter any search criteria in the Search Field at the top of the table. The display will update to display only those entries that contain the search criteria. Delete the search criteria or click on the "x" at the far right of the Search Field to reset the display. Note that you do not have to click on the Search icon after entering the search criteria. The display will update as you enter the criteria. If you enter search criteria and click on the Search icon, click on the Search icon again to display the Search Field.

Note: By default, all traps from all devices are displayed and updated in real-time (indicated by the red "Live" icon at the top-right corner of the table. If you apply a filter, live update is disabled. When you return to the default settings, live update is again enabled. Also note that if you scroll through the table and new traps are received, a "New Traps" message will appear. Click on the message to return to the top of the table and view the new traps.

Basic Trap Information

The Notifications Table provides an overview of each trap. Click on a trap to display detailed information.

Severity - The severity level assigned to the trap (Normal/Warning/Minor/Major/Critical). Note that you can edit the severity level of a trap using the Trap Definition Screen.
Agent IP - The IP address of the device that generated the trap.
Agent Name - The name of the device that generated the trap.
Name - The name of the trap as defined in the MIB.
Synopsis - A brief description of the trap.
Date/Time - The date and time the trap was received by OmniVista Cirrus Server using the OmniVista system clock. However, for traps received that are "replays" of previously-generated traps, the date/time will be adjusted to the time that the original trap was sent. This is calculated by adjusting the time received by the difference between the current upTime of the source device and the upTime contained within the trap itself. Therefore, it is possible for new traps to be added to the display with old timestamps. So, if the network was down for hours, you may suddenly see traps appear from hours ago.

Detailed Trap Information

The Detailed Information pane provides detailed information for the selected trap. Click on a trap to display detailed information.

Name - The name of the trap as defined in the MIB.
Severity - The severity level assigned to the trap in the Notifications Application's Trap Definitions Window (Normal/Warning/Minor/Major/Critical). Note that you can edit the severity level of a trap using the Trap Definition Screen.
Group Name - The AP Group of the Stellar AP Series Device (Stellar AP Series Devices only).
Acknowledged - Indicates whether or not the trap has been acknowledged (True) or not acknowledged (False). See Acknowledging/Deleting Traps for more information.
Trap OID - The trap object identifier number.
Description - A detailed description of the trap as it appears in the MIB.
Synopsis - A brief description of the trap. When a trap has variables associated with it, the values of some or all of the variables may appear in the synopsis. For example, in the trap synopsis "Link down on slot 6 port 2," the numbers "6" and "2" are trap variable values for the link down trap.
Source IP - The IP address of the device that forwarded the trap to OmniVista.
Agent IP - The IP address of the device that generated the trap.
Agent Name - The name of the device that generated the trap, if configured.
Uptime - The length of time the device that sent the trap has been up (or the amount of time since the last reset), specified in days, hours, minutes, and seconds.
Date/Time - The date and time the trap was received by the OmniVista server, using the OmniVista server's system clock. However, for traps received that are "replays" of previously-generated traps, the date/time will be adjusted to the time that the original trap was sent. This is calculated by adjusting the time received by the difference between the current upTime of the source device and the upTime contained within the trap itself. Therefore, it is possible for new traps to be added to the display with old timestamps. So, if the network was down for hours, you may suddenly see traps appear from hours ago.

Note: You can click on the "Show More" link at bottom of the pane to display specific MIB variable information contained in the trap.

Acknowledging/Deleting Specific Traps

You may want to temporarily remove traps from the display by "acknowledging" the traps, or permanently delete traps from the OmniVista Cirrus Server. Select a trap(s) and click on the ACK button at the top of the table to remove the trap(s) from the display. (You can also hover the mouse over a trap status and click on ACK to acknowledge single trap.) The traps will still be stored on the OmniVista Cirrus Server, but will now only by displayed when you set the "Acknowledged" filter to "True". To return an "Acknowledged" Trap to the display, select a trap(s) and click on the UNACK button at the top of the table. To permanently a delete trap(s) from the OmniVista Cirrus Server, selecting the trap(s) and click on the CLEAR button at the top of the table.

You can quickly acknowledge or delete specific Severity types at once using the filter to specify a Severity level, selecting all of the traps in the table and clicking on the ACK or CLEAR button at the top of the table.

Note: Once traps are cleared, the traps are permanently removed from OmniVista.

Acknowledging/Deleting All Traps

To acknowledge all traps in the Notifications Table, click on the Actions button at the top of the screen, select Ack All, and click OK at the Confirmation Prompt. The traps will be removed from the display. The traps will still be stored on the OmniVista Server, but will now only by displayed when you set the "Acknowledged" filter to "True". To permanently delete all displayed traps from the OmniVista Server, click on the Actions button at the top of the screen, select Clear All, and click OK at the Confirmation Prompt.

Note: The Ack All and Clear All buttons are grayed out if any traps are selected in the Notifications Table. To enable the buttons, de-select the traps.

Polling Devices for Traps

To poll a device(s) for new traps, click on the Actions button at the top of the screen and select Poll for Traps. Select the device(s) you want to poll and click on the Poll Now button. The device(s) will immediately be polled for traps.
