Architecture 41

The SNMP traps are shown under the eSNMP tab. SNMP traps are ASN.1

BER-encoded. In the eSNMP the received data is represented in an

XML-style way to improve readability. See the following figure.

Figure 37

eSNMP traps

The eSNMP module can determine the originator of the SNMP trap. For

example in Figure 37 "eSNMP traps" (page 41), an SNMPv1 trap was

received from 10.128.84.22. The SNMP trap also contains some “header”

information, such as the following.

• community, for example public

• enterprise oid, for example 1.3.6.1.4.1.28088.32.1

• generic trap (value between 0 and 6)

• specific trap (0 or >0)

• a timestamp

Optionally additional parameters can be received. The eSNMP module can

handle up to 9 additional parameters, or varbind parameters. Each varbind

parameter is up to 32 characters long.

When an SNMPv1 or SNMPv2 trap is received, a message is sent to

eKERNEL. eKERNEL considers the eSNMP modules as an input program,

and requires the typical parameters needed for generating a message.
