Networking - Switch

Switch types

Networks play critical roles in supporting business operations, supporting communication, and supporting entertainment. Networking switches are a fundamental building block in networks and help to connect devices for the purpose of sharing resources.

A switch will either work at layer 2, the data link layer in the OSI model, or at layer 3 – the network layer that supports routing. The majority of networking switches use Ethernet ports while the other switches are based on fiber channel, InfiniBand, and asynchronous transfer mode (ATM).

Generally, a networking switch irrespective of type should help network admins and other IT professionals to:

  • Configure settings for bandwidth and duplex.
  • Configure port mirroring to allow traffic monitoring
  • Enable MAC filtering as well as other access control features.
  • Enable or disable specific ports
  • Set up the quality of service levels for specific ports
  • Set up SNMP monitoring of devices

Different Types of Switches

Networking switches vary widely depending on the number of devices it can support, network bandwidth/speed, and form factor. Switches for small offices will have anything between 4 and 8 ports and can fit on a desk. For larger office network implementation, switches may have 24 ports, 48 ports, 96 ports, and 128 ports and are rack-mountable between 1U and 4U. Switches vary depending on network speed and tasks to be supported such as 40/100 Gbps, 10 Gigabit (up to 10000 Mbps), gigabit Ethernet (up to 1000 Mbps), power over ethernet and fast Ethernet (10/100 Mbps).

Unmanaged Switches

The unmanaged switches offer fixed configuration on a plug and play basis. It is the most basic switch and there are a few choices in the market. These switches are affordable, but the basic features make them inappropriate for enterprise applications.

Managed Switches

The number of features and level of functionality improves with managed switches, making them ideal for enterprise and business applications. These switches are built with the command-line interface for ease of configuration. Equally, they support SNMP agents that come in handy when troubleshooting network issues.

The security on managed switches is better and will protect different types of traffic. Other features include support for virtual LANs, IP routing, and quality of service settings. Managed switches are more expensive compared to all other types of switches.

Smart Switches

Smart switches refer to switches that possess more features than those of unmanaged switches but do not have the full features of managed switches. Smart switches are more cost-effective than managed switches.

Some of the limitations of the smart switches are a lack of telnet access support, Web GUIs, and a lack of many features for VLANs. They are affordable compared to a fully managed switch and are suitable for a smaller computer network.

Modular Switches

Modular switches allow the addition of expansion modules as the network expands. The expansion modules allow for more networked devices but are application-specific. They may include wireless access points, firewalls, or network analysis tools. The flexibility of a modular networking switch comes at a higher cost.
