4.2.1.3 Trap Sender Examples

In the following snmp_trapsnd command examples:

•The first line is the snmp_trapsnd command.

•The remainder is the display received when running the trap receiver program (snmp_traprcv) without flags included.

1.The following example generates a trap that originated on the localhost (specified by the agent parameter) using the default SNMP version (SNMP Version 1). The -hhost parameter is not specified, so the trap will be sent to the local host.

$ snmp_trapsnd 0.0 local 0 0 0
Message received from 127.0.0.1
SNMPv1-Trap-PDU:
community - 7075626C 6963	public
enterprise - 0.0
agent address - 0.0.0.0
trap type - Cold Start (0)
timeticks - 51938978

2.The following example generates the same trap as in example 1, except that it specifies the use of SNMP Version 2.

$ snmp_trapsnd 0.0 local 0 0 0 "-v2c"

Message received from 127.0.0.1

SNMPv2-Trap-PDU:

sysUpTime.0 - 51938968 = 6 d 0:16:29 snmpTrapOID.0 - 0.0

3.The following example sends values to the node mynode with the community name special.

$ snmp_trapsnd 1.2.3 marley.dec.com 6 33 100 -c special -h mynode Message received from 16.20.208.68
