Rate Limiting on Juniper Networks

 This Tech-recipe describes the steps for setting up rate limiting on Juniper networks.The first step in configuring rate-limiting on a Juniper is to configure the firewall filter, under the firewall section of the router.conf file. The firewall section should be located just after the interface configurations. Choose a filter name based on slot-pic-port-unit, e.g. "rate-limit-t3-0-1-1-0". The first set of statements are for the policer which define the bandwidth characteristics of the filter. It will always be called "p1". The bandwidth limit and burst limits are configured under the policer, as well as what to do when limits are reached (in this case "discard"). Note: Bandwidth is configured in bits per second, Burst is configured in bytes per second. You can use k for Kbps 1000, m for Mbps 1,000,000, or g for Gbps 1,000, 000. The next set of statements define the "term", that is, how we are going to use the policer in this filter. Term should be named "slot-pic-port-unit-traffic". Te... Read More
