trap destination that you want to modify, and then click Modify. In the Modify SNMP Trap Destination dialog box,
modify the parameters.

Downloading MIB Files
You must download the following file before you start monitoring a NetScaler SDX appliance.
SDX-MIB-smiv2.mib. This file is used by SNMPv2 managers and SNMPv2 trap listeners.
The file includes a NetScaler enterprise MIB that provides NetScaler SDX-specific events.
To download MIB files
1. Log on to the Downloads page of the NetScaler SDX appliance user interface.
2. Under SNMP Files, click SNMP v2 - MIB Object Definitions. You can open the file by using a MIB browser.
Adding an SNMP Manager Community
You must configure the NetScaler SDX appliance to allow the appropriate SNMP managers to query it. You must also
provide the SNMP manager with the required appliance-specific information. For an IPv4 SNMP manager you can specify a
host name instead of the manager's IP address. If you do so, you must add a DNS name server that resolves the host name
of the SNMP manager to its IP address.
You must configure at least one SNMP manager. If you do not configure an SNMP manager, the appliance does not accept
or respond to SNMP queries from any IP address on the network. If you configure one or more SNMP managers, the
appliance accepts and responds only to SNMP queries from those specific IP addresses.
To configure an SNMP manager
1. On the Configuration tab, in the navigation pane, expand System, and then expand SNMP.
2. Click Managers.
3. In the details pane, click Add.
4. In the Create SNMP Manager Communitypage, set the following parameters:
SNMP Manager— IPv4 address of the SNMP manager. Alternatively, instead of an IPv4 address, you can specify a
host name that has been assigned to an SNMP manager. If you do so, you must add a DNS name server that resolves
the host name of the SNMP manager to its IP address.
Community— T he SNMP community string. Can consist of 1 to 31 characters that include uppercase and lowercase
letters, numbers, and the hyphen (-), period (.) pound (#), at (@), equals (=), colon (:), and underscore (_) characters.
5. Click Add, and then click Close.
Configuring the NetScaler SDX Appliance for SNMPv3 Queries
Simple Network Management Protocol Version 3 (SNMPv3) is based on the basic structure and architecture of SNMPv1
and SNMPv2. However, SNMPv3 enhances the basic architecture to incorporate administration and security capabilities,
such as authentication, access control, data integrity check, data origin verification, message timeliness check, and data
confidentiality.
The Citrix NetScaler SDX appliance supports the following entities that enable you to implement the security features of
SNMPv3:
