BIGIP LTM SSL offloading statistics

Hi guys,

 

I'd like know statistics about which SSL/TLS suite is used by client in session with ltm.

 

I have many vip for which ltm makes ssl-offload, associated to them there are different ssl profile in which I define the SSL/TLS suite to accept or refuse (e.g. I refuse SSLv2). I'd like encrease the security level accepting TLSv1.1 only, but I don't how many client, now, are connected with SSLv3 or TLSv1.0. If I have a statistic I can be sure about this.

 

Thanks in advance, Andrea

    [root@ve11a:Active:In Sync] config  tmsh show ltm profile client-ssl clientssl | grep -i Protocol

    Thanks nitass,

    I have this output for the command you suggest:

    Protocol                               
  SSL Protocol Version 2                           0
  SSL Protocol Version 3                      231657
  TLS Protocol Version 1.0                   4841104
  TLS Protocol Version 1.1                    154773
  TLS Protocol Version 1.2                   9992868
  DTLS Protocol Version 1                          0

    Now I have new question: when that statistics were reset? During last reboot?

    In addition, I found interesting the output of the entire command "tmsh show ltm profile client-ss", where I can find the explanetion of all statistics? Not only protocol.

    Thanks in advance, Andrea

    you can manually reset it or yes it will be rest when rebooting.

     tmsh reset-stats ltm profile client-ssl clientssl

    I found interesting the output of the entire command "tmsh show ltm profile client-ss", where I can find the explanetion of all statistics? Not only protocol.

    if it is not documented anywhere, you may try to post here (in case someone knows) or open a support case. 🙂
