The ideal rate value depends on how much traffic you use; a good tip is to use values above 200 and monitor your router&#8217;s CPU usage. <\/p>\n\n<pre class=\"wp-block-preformatted\">## Setting the Rate value to 500<br\/>set forwarding-options sampling input rate 500<br\/><br\/>## How to view Juniper settings without \"display-set\"<br\/>forwarding-options {<br\/> sampling {<br\/> input {<br\/> rate 500;<br\/> }<br\/><\/pre>\n\n<p class=\"wp-block-paragraph\">3.
