Fixed In:

Opened: Mar 20, 2015
Severity: 3-Major

Symptoms

Existing flows are not re-evaluated against Virtual Server AFM policies in Kill-on-the-fly if a previous Global or Route Domain AFM rule with action = Accept Decisively is modified to action = Accept.

Impact

Existing flows bypass Virtual Server AFM Policy match evaluation in the sweeper under the conditions specified above.

Conditions

AFM provisioned and licensed. Have a Global AFM (or route domain) rule with action = Accept Decisive and also have a virtual server AFM rule. Initial flow will be allowed due to global AFM rule action being Accept-decisively and will not be matched against Virtual Server Rule. Now, modify the global AFM rule action to Accept. This should trigger Kill-on-the-fly to re-evaluate all existing flows against AFM policies.

Workaround

None

Fix Information

With this fix, existing flows will be evaluated against virtual server ACL policy if a previous Global or Route Domain AFM rule with action = Accept Decisively is modified to action = Accept.
