Citrix Systems CITRIX NETSCALER 9.3 manual Configuring Traps

Citrix NetScaler Administration Guide

To configure SNMP alarms by using the configuration utility

1.In the navigation pane, expand System, expand SNMP, and then click Alarms.

2.In the details pane, select an alarm (for example, Login-Failure), and then click Open.

3.In the Configure SNMP Alarm dialog box, specify values for the following parameters, which correspond to parameters described in "Parameters for configuring SNMP alarms" as shown:

•Severity—severity

•Logging—logging

4.Click OK.

A message appears in the status bar, stating that the alarm has been configured successfully.

Configuring Traps

After configuring the alarms, you need to specify the trap listener to which the NetScaler appliance sends the trap messages. Apart from specifying parameters such as IP address and the destination port of the trap listener, you can specify the type of trap (either generic or specific) and the SNMP version.

You can configure a maximum of 20 trap listeners for receiving either generic or specific traps.

You can also configure the NetScaler to send SNMP trap messages with a source IP, other than the NetScaler IP address (NSIP), to a particular trap listener. You can set the source IP to either a mapped IP address (MIP) or a subnet IP address (SNIP) configured on the NetScaler appliance.

You can also configure the NetScaler to send trap messages to a trap listener on the basis of a severity level. For example, if you set the severity level as Minor for a trap listener, all trap messages of the severity level equal to or greater than Minor (Minor, Major, and Critical) are sent to the trap listener.

If you have defined a community string for the trap listener, you must also specify a community string for each trap that is to be sent to the listener. A trap listener for which a community string has been defined accepts only trap messages that include a community string matching the community string defined in the trap listener. Other trap messages are dropped.

To add an SNMP trap by using the NetScaler command line

At the NetScaler command prompt, type the following commands to set the parameters and verify the configuration:

wadd snmp trap <trapClass> <trapDestination> -version ( V1 V2 ) -destPort <port> - communityName <string> -srcIP <ip_addr> -severity <severity>
