CirrostratusHi,
I did the same test (13.1.0.6 on VE) as Chase and no live update :-(
Steps:
- Client SSL profile with cache disbaled
- Group with only f5-ecc assigned
- Rule with only ECDHE:ECDHE_ECDSA created and assigned to Restrict in group
- nmap test - TLSv1.0, 1.1 and 1.2 ciphers listed
- Edited rule with :!TLSv1:!TLSv1_1
- nmap test - still ciphers for all protocols listed (but when checking in group not TLSv1.0 and 1.1 ciphers present)
- Edited VS by changing client ssl profile to some other and then back to original
- nmap test - now only TLSv1.2 cipher listed.
