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
-h host
parameter is not specified, so the trap will be sent to
the local host.
