System classification is enabled whenever you allow the Autoconf characteristic utilizing the autoconf allow world configuration mode command. The gadget detection acts as an occasion set off, which in flip applies the suitable computerized template to the interface. When the Autoconf characteristic is enabled utilizing the autoconf allow command, the default Autoconf service coverage is utilized to all of the interfaces. For extra details about Autoconf. Autoconf and service-policies presently can’t co-exist on the identical interface and so for interfaces which have templates statically assigned to the interface with service-policy attachment for authentication we could make use of different strategies to make the interface Dynamic.

EEM scripts

EEM scripts use some sort of occasion to set off them. Throughout the EEM script, you possibly can reconfigure interfaces, ship occasion notifications by way of electronic mail and rather more. On this lab we use EEM scripts to reconfigure interfaces on a down occasion to a base closed authentication template, and modify them to low affect mode when a PoE Energy up occasion is detected. The makes use of for such a script are quite a few, and this lab covers one particular use case however an imaginative thoughts can give you many different makes use of for such a characteristic.

Self-Destructing EEM scripts

Self-Destructing EEM scripts are people who delete themselves on termination. Throughout the EEM script, code removes the EEM applet from the configuration, after which writes the configuration to NVRAM. The makes use of for such a script are quite a few, and this lab covers one particular use case however an imaginative thoughts can give you many different makes use of for such a characteristic.
