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.
