Snmptrap is an SNMP application that uses the TRAP Request to send
information to a network manager. One or more fully qualified

identifier. Each variable name is given in the format specified in
variables (5).
If any of the required version 1 parameters,
enterprise-oid ,

uptime

1.3.6.1.4.1.3.1.1 (enterprises.cmu.1.1)
hostname ,

For example
snmptrap -v 1 manager public enterprises.spider test-hub 3 0 '' interfaces.iftable.ifentry.ifindex.1 i 1

packet will be returned and a message will be shown, helping to pinpoint in what

the request will be resent without the bad variable.
