Setting up SNMP Traps

When an SNMP agent detects an alarm condition, it generates a trap (also called a notification) that is sent to configured IP addresses. To set up SNMP traps, see Setting up SNMP Traps, page 2-7.

Failover Traps

Cisco CRS failover traps are sent using CvaProcessStart trap with cvaModuleName description as "New Master xxx" where xxx = Process name. Below is a snapshot of a CRS Engine failover trap.

12/8/2006 13.51:28 SERVER-NAME Trap: P3 cvaProcessStart, ent=ciscoVoiceAppsMIBNotifications, comm-public, cvaAlarmSeverity=notice, cvaModuleName=New Master Engine, cvaProcessId=0

Setting up SNMP Traps

To use SNMP traps, you must designate the SNMP trap destination for the trap messages.

You can specify the following security options for the SNMP traps to ensure that only authorized systems have access to SNMP trap information:

•Community strings—Serve as passwords for SNMP information. A system can exchange SNMP information only with systems in the same community.

•Valid sources for SNMP requests.

•Read/write privileges—Whether systems can only read SNMP information or can read and write information.

For additional information about SNMP security, refer to your Microsoft Windows documentation.

To configure the SNMP trap sender, see these sections:

•Setting the SNMP Trap Receiver, page 2-7

•Setting the SNMP Community Names, page 2-8

Setting the SNMP Trap Receiver

The trap receiver is the network management system (NMS) that receives the SNMP traps. This NMS must have the same SNMP community string as the trap sender. The Cisco CRS system sends traps that can be received by CiscoWorks and by standard third-party NMSs.

To set the SNMP trap receiver, follow these steps:

Step 1 From the Windows desktop, choose Start > Settings > Control Panel.

Step 2 Double-clickAdministrative Tools.

Step 3 Double-click Services.

The Services window appears.

Step 4 Right-click SNMP Services and choose Properties.

Step 5 Click the Traps tab.

Step 6 In the Community name field, enter the community name to which this computer will send trap messages.
