Global Bandwidth Limit Consideration
Traffic shaping rules can be useful in limiting the amount of bandwidth that various applications and traffic types consume. Global limits can also be used to enforce bandwidth limits on a per device basis. A global bandwidth limit applies not only to outbound traffic, but all routed traffic on an MX security appliance or MR access point unless overridden by other configuration settings. This knowledge base article will describe certain considerations that should be taken into account when configuring the global bandwidth limit and how to use traffic shaping rules to override the global bandwidth limit when necessary.
