FAQ-What Is the Function of the seq-number Parameter When an IPSec Policy Is Created?

Issue Description

What is the function of the seq-number parameter when an IPSec policy is created?

Solution

You can create multiple IPSec policies with the same name on a USG9000 to form an IPSec policy group. In an IPSec policy group, the IPSec policy is uniquely identified by the name (policy-name) and sequence number (seq-number). A smaller seq-number value indicates a higher IPSec policy priority.

When an IPSec policy group is applied to an interface, all IPSec policies in the group are applied. The USG9000 preferentially processes the IPSec policy with a smaller seq-number and establishes an IPSec tunnel for the data flow defined in the policy.
