  Here's an example of my agent configuration:

trapcommunity public
createUser _internal MD5 "<none of your beeswax>"
rouser _internal
iquerySecName _internal
notificationEvent linkUpTrap linkUp ifIndex ifAdminStatus ifOperStatus
notificationEvent linkDownTrap linkDown ifIndex ifAdminStatus ifOperStatus
monitor -r 5 -e linkUpTrap "Generate linkUp" ifOperStatus != 2
monitor -r 5 -e linkDownTrap "Generate linkDown" ifOperStatus == 2
authtrapenable 1
sysLocation RLR desk
sysContact dunbugme
sysName CEP10_CEP1.4
rocommunity "rocommunity"
rocommunity "rocommunity2"
trap2sink 192.168.1.145

  I just restarted the agent, it generated nsNotifyShutdown and coldStart almost immediately (as expected).  About 10-15 seconds later, it generated authenticationFailure, and a whole host of linkUp/Down traps for all interfaces in the stack.

  I don't see any obvious problem with the configuration.

  Ah ha, that looks juicy, didn't notice that before.  I'll give it a try:

"-S   indicates that the monitor expression should _not_ be evaluated when the agent first starts up."

  I see.  Does snmpd.conf handle any comment delimiters?  I'd like to comment the trap2sink lines when necessary in our application, if that's possible.  Couldn't see anything about comments in the man page.

  Thanks, Dave.
