Virtual server makes distribution. how can I see the forwarding traff in detail

Hello ,

I have one virtual server for distributing traffic to the other virtual server.  I use one policy to select bakc end virtual server. 

Is there any way to see while forwarding traffic, which parameters is sent to backend Vs. 

for example : 

my vs IP 10.11.12.13:443

clientsslprofs : abc.zz.client_ssl_prof

                       ttt.fte.ss.client_ssl_prod

 serverlsslprof: serverssl          

and policy: entry 1: if host is any of: abc.zz forward VS: a.b.c.zz_vs

                  entry 2 if host is any of : ttt.fte forward VS: t.t.t.tfe_vs

 

Traf between Client1  --> abc.zz

                      Client2 --> ttt.tfe

 

  • Hi Ozzy, I'm sorry but I'm getting lost here, where is the traffic policy applied? Is there a total of 3 Virtual Server objects? 

    In a scenario like the one you described, where a single IP resolves multiple FQDNs, I'm used to just applying all client-ssl profiles to a single Virtual Server, paying attention to https://my.f5.com/manage/s/article/K13452 settings : 

    • specifying the SNI on all clientssl profiles,
    • checking only one of them as "default SNI"
    • matching cipher suites on all profiles.

     

    Then, I'd usually use an iRule to perform pool selection, based on the HTTP::host information
