Symptoms

Traffic policies might not respect the 'first-match' strategy. With 'first-match' specified, it is expected that only one rule may trigger its actions. However, in some cases, more than one rule may have its actions executed.

Impact

Unexpected actions may occur.

Conditions

-- A 'first-match' strategy is used. -- Not all first-match policies are affected, but the exact requirements to trigger this issue are complicated.

Workaround

None.

Fix Information

Traffic policies respect the 'first-match' strategy, and only execute the actions corresponding to the one matching rule.
