SNMP Trap configuration

[arnab.roy]

Hi All,

I am trying to get XI to process SNMP traps, can you tell me where I can set the community strings and all the acls I saw a line saying disableAuthorisation yes but the network device requires a comm string to be present.

Many Thanks
Arnab

Arnab.Roy,

To edit the community string you will need to to do in a per service basis in the Core Config Manager. If you need help accessing the Core Config Manager, the following video has been put together:

http://library.nagios.com/training/self ... ng-the-ccm

After you are in there, you will need to edit the service that is utilizing SNMP. The community string is $ARG1$ and should be edited to suit your needs.

Is it required even if I am using the SNMP Trap Wizard..? In the trap documentaion it doesnt talk about comm strings any where...

I am completely confused now...I am reasonably converse with CCM, I am looking for settings related to where a network device is sending snmp traps : I have followed the following documentation http://assets.nagios.com/downloads/nagi ... ith_XI.pdf it doesnt seem to work.....

If you had not set, or incorrectly set the comm string in your initial configuration with the wizard you would need to go into Core Config Manager to change the string to your necessary value. Otherwise you could try deleting the Host or Service (keeping in mind this will destroy the setup you've done thus far to it) and completing the wizard again, otherwise you will have to go into the Core Config Manager. The XI SNMP trap wizard has a Community String field that defaults to 'public'. If you have changed the default in your own network it may not work. When you say trap documentation did you mean this doc?

Also, it may be worth investigating whether or not a firewall is getting in the way somewhere.

Hi NIcholas,

You have got me wrong, it seems the document you have refered me is where nagios is the trap sender, I am talking about when Nagios is trap receiver.. using SNMPTT

Arnab,

I misunderstood your aims.

Could you run this on your Nagios server you're trying to recieve traps on?

Code: Select all

service iptables status | grep 162

and post what it returns?

Community strings should not be necessary when using traps, only in active requests, and we didn't use them when testing and documenting. If you must use them, you may want to look at the notes on http://snmptt.sourceforge.net/docs/snmp ... ringSNMPTT.

OK it has somehow changed from waiting for trap to TRAP Reset , what does this mean ?
