SNMP Traps

A trap is an unsolicited message that is sent from the

E1 NTU to an SNMP manager when the device detects certain, pre-specified conditions. These traps enable the SNMP manager to monitor the state of the network.

The SNMP Trap configuration option must be enabled for trap messages to be sent over the communications link. You must specify the number of SNMP managers that are to receive traps from this device, an IP address for each SNMP manager specified, and the type of traps to be sent from this device. For more information, refer to Appendix C, Configuration Options, and the Configuring SNMP Traps section in Chapter 3, Operation.

Trap types consist of the following:

General traps ± include warmStart and authenticationFailure. The device sends a warmStart trap after it has been reset to indicate that it has just reinitialized itself. The device sends an authenticationFailure trap when it has received an SNMP protocol message that has not been properly authenticated. These traps are set by the Gen Trap configuration option.

Enterprise Specific traps ± signify that the device has recognized an enterprise-specific event. See Table 4-5for enterprise-specific traps. These traps are set by the Entp Trap configuration option.

Link Traps ± identify the condition of the communications interface, either linkDown (one of the communications interfaces has failed) or linkUp (one of the communications interfaces has just come up). These traps are set by the Link Trap configuration option. The communications interfaces for which these traps can be generated are specified by the Trap I/F configuration option. Table 4-6defines traps for each interface.

Enterprise-Specific Trap Definitions

Trap Value

Event

 

 

enterpriseClockFail(1)

The currently configured

 

primary clock source has

 

failed.

 

 

enterpriseSelfTestFail(2)

A device hardware failure

 

is detected at self-test.

 

This trap is generated after

 

device initialization.

 

 

enterpriseDeviceFail(3)

An internal device failure is

 

detected by the operating

 

software.

 

 

enterpriseSecClockFail(4)

The currently configured

 

secondary clock source

 

has failed.

 

 

enterpriseTestStart(5)

A test is initiated.

 

 

enterpriseTestClear(105)

A test is concluded.

Trap Meaning

 

 

HDSL Network

Up = No alarm or test

 

conditions.

 

Down = Alarm or test

 

conditions.

 

 

G.703 DTE

Up = No alarm or test

 

conditions, and the

 

interface is enabled.

 

Down = Alarm or test

 

conditions, or the interface

 

is disabled.

 

 

Synchronous Data Ports

Up = No test conditions,

 

the port is assigned to a

 

network interface, and both

 

CTS and DSR are ON.

 

Down = Test conditions,

 

the port is unassigned, or

 

either CTS or DSR is off.
