CTS-Manager snmpInBadCommunityNames increasing

I have a security alarm I can't remove on a CTS-Manager


By digging the logs and capture traffic, it seems there is an internal snmp mecanism in the device using / generating bad snmp community names

There are about 163 bad requests per 5 minutes ...


Please see attached some informations or logs / analysis retrieved from the CTS-Manager server

Hardware Model: 7835H2
Software Version: (167)


How to solve internal requests to not generate snmp bad community issues?

Hello Oliver

Certificate name 'mxcorporatetp'. Unit 'CTM-trust'. Type 'trust-cert'. Expiration: 'Fri Apr 8 06:35:16:000 UTC 2011'.||Please delete this certificate and uplaod a valid certificate.

Also please try this link:

The total number of SNMP PDUs delivered to the SNMP protocol entity which used a SNMP community name not
known to said entity.

Can you attach full CTS MAN logs?

Hello Rafal

many thanks for your reply!!! I have attached the full logs and it is currently being queued for virus analysis.

The attachment is added to the first message of this thread.

I have also attached some picture related to the certificate alarms seen on the web administrator page

I am going to check on that direction to see how to solve this ...

No problem Oliver.

I will look it up. I think best would be if you could open a TAC case in parallel.
