SNMP Traps

A trap is an unsolicited message that is sent from the

E1 DSU/CSU 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 4-4 for 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 4-5 defines 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.

Table 4-5

SNMP Trap per Interface

Interface	Trap Meaning
Network E1	Up = No alarm conditions.
	Down = Alarm conditions.
DTE Drop/Insert	Up = No alarm conditions
	and interface is enabled.
	Down = Alarm conditions
	or interface is disabled.
Synchronous Data Ports	Up = Port assigned to a
	network interface and both
	CTS and DSR are ON.
	Down = Port unassigned
	or either CTS or DSR are
	off.
