Chapter 2

SNMP

Topics:

• Importing MIB Files to the

SNMP Manager and Trap

Listener

• Configuring the NetScaler to

Generate SNMPv1 and

SNMPv2 Traps

• Configuring the NetScaler for

SNMP v1 and v2 Queries

• Configuring SNMP Alarms for

Rate Limiting

• Configuring the NetScaler for

SNMPv3 Queries

You can use Simple Network Management Protocol (SNMP) to

configure the SNMP agent on the Citrix

NetScaler

appliance

to generate asynchronous events, which are called traps. The

traps are generated whenever there are abnormal conditions

on the NetScaler. The traps are then sent to a remote device

called a trap listener, which signals the abnormal condition

on the NetScaler appliance. Or, you can query the SNMP agent

for System-specific information from a remote device called

an SNMP manager. The agent then searches the management

information base (MIB) for the data requested and sends the

data to the SNMP manager.

The SNMP agent on the NetScaler can generate traps

compliant with SNMPv1 and SNMPv2 only. For querying, the

SNMP agent supports SNMP version 1 (SNMPv1), SNMP version 2

(SNMPv2), and SNMP version 3 (SNMPv3).

The following figure illustrates a network with a NetScaler

that has SNMP enabled and configured. In the figure, each

SNMP network management application uses SNMP to

communicate with the SNMP agent on the NetScaler. The

SNMP agent searches its management information base (MIB)

to collect the data requested by the SNMP Manager and

provides the information to the application.
