Hi Brian,
I'm writing you because there doesn't seem to be that many people on GS who really know Rmon & SNMP that well ( or don't reply to questions about this topic.) So, I'm hoping maybe you could help me better understand this. (True guru's and great persons don't often come in one package.)
I'm trying to understand the inter-dependencies between certain commands and unfortunately the documentation is not that comprehensive and I can't test this in my lab.
Re: the Rmon event command.
Can or does this command do anything if the Rmon alarm command isn't also configured? If yes, what?
If the trap <community> option is used, what happens if no snmp commands are configured? (I assume not much because the device doesn't know where to send the trap, correct?) Is this option needed so that an snmp mgr can poll this device and get the traps that have accumulated, again assuming no snmp commands have been configured?
On the other hand, if the snmp-server community command is configured, is the trap <community> still required? Why?
The command reference says, "This configuration also generates a Simple Network Management Protocol (SNMP) trap when the event is triggered." What does generate an snmp trap actually mean?
What does Rmon (or snmp) do with the other 2 options, description and owner?
Re: the Rmon alarm command.
Can this command be used without the Rmon event command? If yes, what? My guess is that without the Rmon alarm also configured, this command just defines and stores any triggered alarms until an snmp mgr polls for the info. I am close?
I'm sorry for all the questions. I've checked all the Cisco documentation and several books but still I haven't been able to find out much detail about how these various parameters real work and what they actually do. Any help you can provide is greatly appreciated.
Thanks, Tim
