Figure 40: eSNMP traps
The eSNMP module can determine the originator of the SNMP trap. For example, in Figure
40: eSNMP traps on page 43, 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 nine
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. See the following figure.
