Nimbostratusenable tls1.2 on management interface on F5 ltm running version 10.x
Hi Experts ,
Legacy F5 is having below image and we would like to enable tls1.2 for httpd for management interface so that we can access Web using new browsers.
Sys::Version
Main Package
Product BIG-IP
Version 10.2.4
Build 817.0
Edition Hotfix HF7
Date Mon May 20 15:08:56 PDT 2013
We are folllowing stpes mentioned in the "https://my.f5.com/manage/s/article/K40232071" , unfortunately this is for 11.x and above versions.
We are getting below error while changing the ssl to tls1.2.
(Active)(tmos)# modify /sys httpd ssl-ciphersuite 'ALL:!ADH:!EXPORT:!eNULL:!MD5:!DES:!SSLv2:!SSLv3:!TLSv1:!TLSv1.1'

your valuable suggestion helps us to fix GUI issues.
from the Browser we are getting ,

First I would run the following command to see what the configuration is.
list sys httpd
Next when you end the following I would use the question mark to see what configuration options are available to you. Sadly I do not have access to an F5 appliance with this code version so I cannot provide the specific command. Essentially you need to create the appropriate cipher suite command to do what you want and that changes a bit from version to version.
modify sys httpd ssl-ciphersuite
TechHi Paulius ,
Thank you for your reply.
list sys httpd
sys httpd {
allow { 10.41.32.0/255.255.224.0 }

ssl-ciphersuite ALL:!ADH:!EXPORT56:!eNULL:!MD5:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP
}We have tried below commands but no luck as these commands are for 11.x and above .
To restrict Configuration utility access to clients using TLS 1.2 or RC4-SHA ciphers, type the following command:
modify /sys httpd ssl-ciphersuite 'ALL:!ADH:!EXPORT:!eNULL:!MD5:!DES:RC4-SHA:!SSLv2:-TLSv1:-SSLv3:-TLSv1.1'
Alternatively, if you can restrict to only TLS 1.2 cipher, then type the following command instead:
modify /sys httpd ssl-ciphersuite 'ALL:!ADH:!EXPORT:!eNULL:!MD5:!DES:!SSLv2:!SSLv3:!TLSv1:!TLSv1.1'
