Extra issues lined within the lab;

Autoconf

In these labs, we use Autoconf, an answer that manages port configurations for knowledge or voice VLAN, high quality of service (QoS) parameters, storm management, and MAC-based port safety on finish gadgets to deploy configuration in an automatic manner within the entry layer of a community. Machine classification is enabled while you allow the Autoconf characteristic utilizing the autoconf allow international configuration mode command. The system 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 at the moment 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. Inside the EEM script, you may reconfigure interfaces, ship occasion notifications through electronic mail and far 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. Inside 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.
