manageable and unmanageable

manageable and unmanageable
manageable and unmanageable :
  • Unmanaged switches : These switches have no configuration interface or options. They are typically found in SOHO (small office/home office) or home environments.
  • Managed switches : These are ones which allow access to one or more interfaces for the purpose of configuration or management of features such as Spanning Tree Protocol, Port Speed, VLANS, etc. High-end or “enterprise” switches, provide a serial console and command-line access via telnet and ssh, as well as management via SNMP. More recent devices also provide a web interface. Limited functions, such as a complete reset by pushing buttons on the switch are usually also provided. Managed switches are found in medium/large “enterprise” networks and though more expensive are of higher quality (e.g. with a backplane with higher transfer speeds). The task of managing usually requires understanding of Layer 2 networks (e.g. Ethernet).
  • Smart (or intelligent) switches : These are managed switches with a limited set of features. Likewise “web-managed” switches are switches which fall in 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 configuration of basic settings, such as VLANs, port-speed and duplex.[10]
  • Web-managed switches : Similar in functionality to a Smart switch. A Web-managed switch is configured through a browser instead of via a desktop utility.
