Unable to configure traps in netsight console, getting an message : "unable to find events in log file"


We recently purchased netsight software, and was able to discover all the switches and getting all events messages. But unable to get the traps and syslogs. Followed the procedure mentioned in document, but not helped. I am getting an warning message in traps window "unable to find events in log file" .
Request you to please support for getting the same.

Hi Prasanth,

Welcome to the HUB.

What is the model if the switch?
Can you post a link or the name of the document which you are referring to?

Can you check if the issue mentioned in the article is relevant to your issue?

We are using A4H124-24TX is the model of switch and i referred "b0700ej_c" this document as well as web solutions for resolution.
  1. ssh to the Netsight Appliance
  2. type the command: service nssnmptrapd restart
Should i execute this command in switch or netsight installed station?

Hello,

You need to restart the nssnmptrapd service in the NetSight server.

Thanks

Hello,

Can you turn off the firewall? Sounds like it's NetSight install on a Windows system?

Also, I would install and run wireshark on the NetSight server and trigger a trap. I would be good to verify that the trap is making it to NetSight, and then investigate why NetSight isn't processing the trap.

Thanks

Yes we installed netsight in Windows server 2008 R2, we allowed everthing in firewall (any-any).
It would be any configuration missing? I am communication through SNMPV3 ....

Hi Prasanth,

Yes, the switch should be (enabled/configured) to send traps as well as syslog pointed towards the Netsight IP in case if this is not done yet.

If possible try to trigger a Trap and do a packet capture in Netsight and see if you can see the SNMP traps.

here is an article to help you on the same.

https://gtacknowledge.extremenetworks.com/articles/Solution/No-traps-displayed-in-Netsight-Console

Or the easy way as Ryan stated install Wireshark in the Windows server where Netsight is running and capture the packets and look for the SNMP traps in the packet capture.
"tcpdump -i eth0 port 162" is this port number is same for all services?
Yes, the switch should be (enabled/configured) to send traps as well as syslog pointed towards the Netsight IP in case if this is not done yet. ? how to ensure this one?

set linkflap action fe.1.3 disableInterface
set linkflap action fe.1.3 genSyslogEntry
set linkflap action fe.1.3 genTrap .... "Same for all 28 ports"

set snmp group ABCDEV3@ user ABC6service security-model usm

set snmp notify TVTrapTag tag TVTrapTag
set snmp targetaddr TVABCDservice XXX.XXX.XXX.XXX param TV1ABCDservice mask 0.0.0.0 taglist TVInformTag nonVolatile

Were you able to identify the cause?

Thanks

Hi,

In traps receiver configuration, it is showing that traps are receiving in 17 devices

If the device is configured for SNMP and could be reached from EMC/Netsight the only thing that you'd need to do is to click on "register trap reveiver" in EMC and it's enabled = EMC configures the device to send traps.

Might be that you've messed up because you've configured the trap receiver via switch CLI and then also via EMC.

I'd delete the SNMP trap receiver config from the switch and this time only do it via EMC.

As a example here the commands that where added via EMC after I've selected "register trap receiver".....

set snmp notify TVTrapTag tag TVTrapTag
set snmp targetaddr TVpublic 172.24.24.110 param TV1public mask 0.0.0.0 taglist TVTrapTag
set snmp targetparams TV1public user public security-model v1 message-processing v1 noauthentication nonvolatile

For troubleshooting you'd use the commands....
show snmp targetaddr
show snmp targetparams

I have tried this command line, still traps are not getting, shall i send the snap shot of "show snmp targetaddr" and "show snmp targetparams" ?

Dear Ronald,

We have purchased the netsight software and Extreme switch (more than 100), can you people support us by assigning local resource to resolve the issue?

Sorry for the confusion but I don't work for Extreme.
https://community.extremenetworks.com/extreme/topics/extreme-embassadors-program

Where are you from ?

You'd open a ticket from the GTAC so someone could support you in a remote session - I think in this case that would be the better/easier solution.
