net snmp - Issue sending SNMPv3 trap with the command snmptrap

Question

I need to send a trap using the snmptrap command.

1. If I use SNMPv1 the trap is sent:

snmptrap -v 1 -c public localhost EXAMPLE-MIB::MyTestFFAlarmTrap  localhost 4 0 '' EXAMPLE-MIB::trapType i 1 
EXAMPLE-MIB::trapTimeStamp t 500 
EXAMPLE-MIB::trapID s "device-1" 
EXAMPLE-MIB::trapCode i 3 
EXAMPLE-MIB::trapDescription s "Power alarm"

2. If I use SNMPv3 the trap is not sent. I know the configuration is correct because I am sending these same traps from an SNMP agent using SNMPv3 and it works.

I only have the problem when sending them with the snmptrap command.

• Option 1:

snmptrap -v3 -e 0x0102030405 -u usr1 -a SHA -A "12345678" -x DES -X "12345678" localhost   1000 EXAMPLE-MIB::MyTestFFAlarmTrap  localhost 4 0 '' EXAMPLE-MIB::trapType i 1 
EXAMPLE-MIB::trapTimeStamp t 500 
EXAMPLE-MIB::trapID s "device-1" 
EXAMPLE-MIB::trapCode i 3 
EXAMPLE-MIB::trapDescription s "Power alarm"

The screen shows the error:

localhost: Unknown Object Identifier (Sub-id not found: (top) -> localhost)

• Option 2:

snmptrap -v3 -e 0x0102030405 -u usr1 -a SHA -A "12345678" -x DES -X "12345678" localhost 4 0 '' EXAMPLE-MIB::MyTestFFAlarmTrap  localhost 4 0 '' EXAMPLE-MIB::trapType i 1 
EXAMPLE-MIB::trapTimeStamp t 500 
EXAMPLE-MIB::trapID s "device-1" 
EXAMPLE-MIB::trapCode i 3 
EXAMPLE-MIB::trapDescription s "Power alarm"

The screen shows the error:

: Unknown Object Identifier (Sub-id not found: (top) -> )

• Option 3:

snmptrap -v3 -e 0x0102030405 -u usr1 -a SHA -A "12345678" -x DES -X "12345678" localhost '' EXAMPLE-MIB::MyTestFFAlarmTrap  localhost 4 0 '' EXAMPLE-MIB::trapType i 1 
EXAMPLE-MIB::trapTimeStamp t 500 
EXAMPLE-MIB::trapID s "device-1" 
EXAMPLE-MIB::trapCode i 3 
EXAMPLE-MIB::trapDescription s "Power alarm"

The screen shows the error:

localhost: Unknown Object Identifier (Sub-id not found: (top) -> localhost)

• Option 4:

snmptrap -v3 -e 0x0102030405 -u usr1 -a SHA -A "12345678" -x DES -X "12345678" 127.0.0.1 '' EXAMPLE-MIB::MyTestFFAlarmTrap  localhost 4 0 '' EXAMPLE-MIB::trapType i 1 
EXAMPLE-MIB::trapTimeStamp t 500 
EXAMPLE-MIB::trapID s "device-1" 
EXAMPLE-MIB::trapCode i 3 
EXAMPLE-MIB::trapDescription s "Power alarm"

The screen shows the error:

localhost: Unknown Object Identifier (Sub-id not found: (top) -> localhost)

I have checked the syntax of the snmptrap command in a tutorial or forum that I have found on the internet and I do not see the reason for the error.

I appreciate any help.
