Benefit

• RSPAN (Remote SPAN) allows network administrators to remotely

monitor ports in a Layer 2 switch network from any other switch in the

same network.

• Domain Name Services (DNS) provide IP address resolution with

user-deﬁned device names.

• Trivial File Transfer Protocol (TFTP) reduces the cost of administering

software upgrades by downloading from a centralized location.

• Network Timing Protocol (NTP) provides an accurate and consistent

timestamp to all switches within the intranet.

• Multifunction LEDs per port for port status, half-duplex/full-duplex, 10BaseT/

100BaseTX/1000BaseT indication, as well as switch-level status LEDs for

system, redundant power supply, and bandwidth utilization provide a

comprehensive and convenient visual management system.
