HTTPS Probe on ACE

jason.williams

We have some webserver behind our ACE that use SSL certificates that are issued by an internal CA.

Do I need to do anything special in order to probe HTTPS?  Does the ACE need the internal CA to be trusted?

Thanks.

Hi,

If https server is working properly, only you need to do is configure https probe on ACE like below.

You do not have to anything related certificate on ACE side.

ACE-A327/context02# show running-config
Generating configuration....

probe https HTTPS
  interval 15
  passdetect interval 60
  ssl version all
  expect status 200 200
  open 1

rserver host S1
  ip address 10.1.142.209
  inservice


serverfarm host SF
  probe HTTPS
  rserver S1
    inservice

interface vlan 11
  ip address 10.1.142.1 255.255.255.0
  no shutdown

Additionaly, you can specify cipher in client hello, also you can select ssl/tls version.
