SNMP Traps

trap is an unsolicited message that is sent from the

DSU/CSU to an SNMP manager when the device detects

certain, prespecified conditions. These traps enable the

SNMP manager to gauge the state of the network. The

SNMP Trap Enable 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. See Appendix C,

Configuration

Options

for more information about how to set these traps.

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 3-7 for enterprise-specific traps. These traps

are set by the Entp Trap configuration option.

•

Link T

raps

– 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.
