Configuration options

Unmanaged switches — These switches accept no agreement interface or options. They are bung and play. They are about the atomic big-ticket switches, begin in home, SOHO, or baby businesses. They can be desktop or arbor mounted.

Managed switches — These switches accept one or added methods to adapt the operation of the switch. Common administration methods include: a command-line interface (CLI) accessed via consecutive console, telnet or Secure Shell, an anchored Simple Network Administration Protocol (SNMP) abettor acceptance administration from a bound animate or administration station, or a web interface for administration from a web browser. Examples of agreement changes that one can do from a managed about-face include: accredit appearance such as Spanning Tree Protocol, set anchorage bandwidth, actualize or adapt Virtual LANs (VLANs), etc. Two sub-classes of managed switches are marketed today:

Acute (or intelligent) switches — These are managed switches with a bound set of administration features. Likewise "web-managed" switches are switches which abatement in a bazaar alcove amid unmanaged and managed. For a amount abundant lower than a absolutely managed about-face they accommodate a web interface (and usually no CLI access) and acquiesce agreement of basal settings, such as VLANs, port-bandwidth and duplex.9

Action Managed (or absolutely managed) switches — These accept a abounding set of administration features, including CLI, SNMP agent, and web interface. They may accept added appearance to dispense configurations, such as the adeptness to display, modify, advancement and restore configurations. Compared with acute switches, action switches accept added appearance that can be customized or optimized, and are about added big-ticket than acute switches. Action switches are about begin in networks with beyond amount of switches and connections, area centralized administration is a cogent accumulation in authoritative time and effort. A stackable about-face is a adaptation of enterprise-managed switch.
