(Optional) Setting the Global Aging Time of a Reflective ACL

(Optional) Setting the Global Aging Time of a Reflective ACL

Context

If a packet matching a reflective ACL rule passes through the interface within an aging time, the reflective ACL rule on the interface is retained until the next aging time expires. If no packet that matches the reflective ACL rule passes through the interface within the aging time, the reflective ACL rule is deleted on the interface.

If the aging time of a reflective ACL is set in the interface view, the aging time specified in the interface view takes effect. Otherwise, the aging time specified in the system view takes effect.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run traffic-reflect timeout time-value

    The global aging time of a reflective ACL is set.

    By default, the global aging time of a reflective ACL is 300 seconds.
