Fixed In:
15.1.0, 13.1.3
Opened: Apr 29, 2019 Severity: 3-Major
Upon upgrading from 12.1.x, the config fails to load with an error similar to the following: 01071aa6:3: Dos DNS query data bad actor can not be enabled if per-source detection/limit pps is less than 1% of the Dos vector (a) rate threshold setting for sub-profile (PROFILE_DOS_NETWORK_VS-ADIB-GTM-ID177_53_UDP) of Dos profile (/Common/PROFILE_DOS_NETWORK_VS-ADIB-GTM-ID177_53_UDP).
During upgrade, the BIG-IP system fails to convert these thresholds to the new default value of 'infinite'. After upgrade, the configuration fails to load.
-- AFM configured. -- One or more SIP or DNS vectors are configured with the rate_threshold values set to the default in 12.x. + For SIP, the rate_threshold value in 12.x is 30000. + For DNS, the rate_threshold value in 12.x is 50000.
Manually edit the profile to disable bad-actor, or change the DNS and SIP default rate_threshold value to 'infinite', then config can be loaded. For example, in this affected configuration for DNS: dns-query-vector { a { allow-advertisement disabled ... rate-increase 500 rate-limit 250000 rate-threshold 50000 <<--- } Change it to this: dns-query-vector { a { allow-advertisement disabled ... rate-increase 500 rate-limit 250000 rate-threshold infinite } At that point, the configuration should load successfully.
DNS and SIP default rate_threshold value of 50000 and 30000 of 12.1.x are now converted to default value of 'infinite' during upgrade, so the configuration loads as expected.
