The switch will automatically detect the speed of connected devices to accommodate 10,
100, 1000Mbps on the RJ45 ports. All RJ45 ports support the Auto MDI/MDIX function.
With the built-in Web-based management functionality, managing and configuring the
switch is easy. From cabinet management to port-level control and monitoring, you can
visually configure and manage your network via your Web Browser. The GSM switch
can be managed via Telnet, Console with either CLI commands or menu driven
commands, or SNMP Management.
Ethernet switching technology dramatically boosted the total bandwidth of a network,
eliminating congestion problems inherent with the carrier sense multiple access with the
collision detection (CSMA/CD) protocol and greatly reduced unnecessary transmissions.
This revolutionized networking. First, by allowing two-way, simultaneous transmissions
over the same port (full-duplex), bandwidth was essentially doubled.
reducing the collision domain to a single switch-port, the need for carrier sensing was
eliminated. Third, by using the store-and-forward technology's approach of inspecting
each packet to intercept corrupt or redundant data, switching eliminated unnecessary
transmissions that slow down network traffic.
Auto-negotiation regulates the speed and duplex of each port, based on the capability of
both devices. Flow-control allows transmission from a 100Mbps node to a 10Mbps node
without loss of data. Auto-negotiation and flow-control may have to be disabled for some
networking operations that involve legacy equipment. Disabling the auto-negotiation is
accomplished by hard setting the speed or duplex mode of a port.
