When session tracking actions are enabled in ASM policy, an HTTP request may be blocked based on HTTP session or username and illegal traffic that has been sent from this session. The blocked request is reported in the security events log, but there is no option to release the username using the Configuration utility.
Usernames and HTTP sessions are blocked by ASM without an option to release them from the Configuration utility.
High availability (HA) setup, and ASM with Session tracking actions enabled.
Stop and start tmm on all devices in the HA group by running the following commands: -- bigstart stop tmm -- bigstart start tmm
Using the Configuration utility, BIG-IP system administrators can now release blocked usernames and sessions. This is done on the Session Tracking Status screen.
