[j-nsp] Testing SNMP traps

[Jonathan Call]

Based off this site, there is suppose to be a way to test SNMP traps:

http://juniper.cluepon.net/index.php/ER_SNMP_trap_testing

However, on my 4200EX, no such command is available via the CLI:

me at myrouter> test snmp 
                                 ^
syntax error, expecting <command>.

I'm trying to test a few chassis events (i.e.  jnxFanFailure)

Is this a shell command? If so I can't figure out any sort of syntax to make it work.
