SNMP_TRAP: SSL cert EXPIRED

Getting heaps of these messages in my syslog server:

 

 

SNMP_TRAP: SSL cert EXPIRED from IP ::ffff:203.42.xx.xx:62255

 

 

THe problem is that none of my SSL certs are expired and the public IP it lists is not even one that my company owns... its a random IP.

 

 

Any thoughts?

    Hi Luca,

     

     

    Can you run tcpdump or something like it on your syslog server to see what the source IP is for the trap?

     

     

    How many LTMs do you have? Can you run checkcert -v on your LTMs to see if there are any expired certs? Maybe it's a default cert for the GUI?

    We have numerous LTMs. This error is comming from two LTMs that are in a HA cluster.

     

     

    We have about 10 certs on this device, the earliest one expires in 2013.

    Actually just looking around a bit under "System ›› Device Certificates ›› Trusted Device Certificates" there are a few certs that have exipred but i don't know what they are.

     

     

    There is one names - DHCP-217, My company

     

     

    and

     

    localhost.localdomain, my company.

    Anyone got any other suggestions here?

     

    I can't see anything else that would be causing this.

     

     

    Might log a case with F5 anyway.

    i understand you are correct. the message could be caused by device certificate.
