Technical points:1. The GEO directive defines a whitelist $whiteiplist with a default value of 1, all of which are restricted. If the client IP matches the IP listed in the whitelist, the $whiteiplist value is 0, which is unrestricted.2. The map directive is to map the $whiteiplist value to 1, which is the restricted IP, to the client IP. The

Introduction
As the core network switch of our company, the CISCO3550 has been running stably for many years, and its functions can also meet our needs. However, its port speed limit function is not as easy to implement as some other switches, fortunately, the implementation method has been found recently. After the configuration is complete, it is verified with the iperf software. The result shows that thi
