Managed switches have one or more commutateur cisco to modify the operation of the switch. Common management methods include: Examples of configuration changes that one can do from a commutateur cisco switch include: Two sub-classes of managed switches are smart and enterprise managed switches.


Smart or intelligent switches are managed switches with a limited set of management features. Likewise "web-managed" switches are switches which fall into a market niche between unmanaged and managed. For a price much lower than a fully managed switch they provide a web interface and usually no CLI access and allow commutateur cisco of basic settings, such as VLANs, port-bandwidth and duplex.

They may have additional features to manipulate configurations, such as the ability to display, modify, backup and restore configurations.

These monitoring features are rarely present on consumer-grade switches. Two popular methods that are specifically designed to allow a network analyst to monitor traffic are: Another method to monitor may be to connect a layer-1 hub commutateur cisco the monitored device and its switch port.
