Integrating Dell PowerConnect W-AirWave 7.4

AMP with Centralized NMS Event Correlation

0511042-01 | December 2011 1

Overview

This document describes AMP’s alert/trap workflow when integrating with a centralized NMS Event Correlation

System, using the following topics:

“Adding NMS Event Correlation Servers to AMP” on page1

“Configuring Alerts/Traps in AMP” on page1

“Viewing Alerts in Various Destinations” on page2

“Acknowledging Alerts” on page3

“Compiling AMP’s MIB on NMS” on page3

“Matching AMP’s Severity in the NMS Event Correlation Servers” on page3

“Enhanced Integration” on page4

“Actual MIB” on page4

Adding NMS Event Correlation Servers to AMP

1. Navigate to AMP Setup > NMS and click Add.

2. Configure server settings, as shown in Figure 1.

Figure 1 AMP Setup > NMS Page Illustration

Configuring Alerts/Traps in AMP

1. Navigate to Systems > Triggers, as shown in Figure 2.

2. Select one of the built-in Alerts/Traps.

OID Breakdown

12028.4.15.1.102 contains Severity Code

2 = Normal

3 = Warning

4 = Minor

5 = Major

6 = Critical

12028.4.15.1.103 contains several fields separated by colons

Object Type {Client, AMP, Device/AP, Group)

Object Name and URL (the URL is optional, if it exist then it will be separated by a dash “-“}

Trap Description and Evaluation Elements

12028.4.15.1.104 contains device IP Address

Group Traps will contain AMP’s IP address.

Acknowledging Alerts

AMP alerts must be manually acknowledge from the System > Alert page. AMP does not currently provide an

external interface to acknowledge alerts from an NMS server.

Compiling AMP’s MIB on NMS

1. Navigate to AMP Setup > NMS.

2. Click on the Download link.

3. Transfer to NMS server.

4. Compile on NMS server.

Matching AMP’s Severity in the NMS Event Correlation Servers

Most NMS Event Correlation systems have the ability to color code and esclate based on information received in

the trap, as shown in Figure 5. The OID 12028.4.15.1.102 contians AMP’s severity code.

Enhanced Integration

AMP has enhanced integration modules with several NMS Event Correlation Systems. These integrations

provide enhanced functionality like quicklink porblem diagnostics, configuration, and WLAN topology views.
