Receiving SNMP V3 traps

[rajasegar]

Hi,

Does SNMP V3 traps require different setup compared to SNMP V2?
Anyone can confirm this?

Thanks

You need to configure snmptrapd to accept SNMPv3 traps or informs, add something like this to the bottom of your /etc/snmp/snmptrapd.conf:

For SNMPv3 informs:

Code: Select all

createUser snmpv3informuser SHA 'authpass' AES 'privpass'
authUser log,execute,net snmpv3informuser

Now restart snmptrapd:

Code: Select all

service snmptrapd restart

You can then test it out from the command line and you should see it show up in /var/log/messages:

Code: Select all

snmpinform -v 3 -u snmpv3informuser -a SHA -A authpass -x AES -X privpass -l authPriv localhost 42 coldStart

For SNMPv3 traps:

Code: Select all

createUser -e 0x8000000001020304 snmpv3trapuser SHA 'authpass' AES 'privpass'
authUser log,execute,net snmpv3trapuser

Now restart snmptrapd:

Code: Select all

service snmptrapd restart

You can then test it out from the command line and you should see it show up in /var/log/messages:

Code: Select all

snmptrap -v 3 -n "" -a SHA -A 'authpass' -x AES -X 'privpass' -l authPriv -u snmpv3trapuser -e 0x8000000001020304 localhost 0 coldStart

Taken and adjusted from here:
- Read here for more information but you should only put any configuration in /etc/snmp/snmptrapd.conf (ignore the files listed in the guide).

Thanks ssax for the detailed help.
It is working fine using the test scripts.

You can close this up now.
