• Switch Port Analyzing (SPAN) port monitors traffic of a
single port from a single network analyzer or RMON
probe
• Autoconfiguration eases deployment of switches in
the network by automatically configuring multiple
switches across a network via a boot server
• 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 Time Protocol (NTP) provides an accurate and
consistent timestamp to all switches within the intranet
• Spanning Tree Root Guard (STRG) prevents edge devices
that are not in the network administrator’s control from
becoming STP root nodes
• Multi-function LEDs per port for Port Status, half-duplex/
full-duplex, 10BaseT/100BaseTX/1000BaseT indication
as well as switch-level status LEDs for system, RPS, and
bandwidth utilization provide a comprehensive and
convenient visual management system
Security and Redundancy
• IEEE 802.1x support (planned future software support)
• Cisco Uplink Fast technology ensures quick fail-over
(typically fewer than 3 seconds) recovery enhancing
overall network stability and reliability
• Private VLAN Edge provides security and isolation
between ports on a switch, ensuring that voice traffic
travels directly from its entry point to the aggregation
device through a virtual path and cannot be directed to a
different port
• MAC-based port level security prevents unauthorized
stations from accessing the switch
• User-selectable address learning mode simplifies
configuration and enhances security
• IEEE 802.1D STP support for redundant backbone
connections and loop-free networks simplifies network
configuration and improves fault tolerance
• Support for the Cisco Redundant Power System 300 (RPS
300), which provides a backup internal power supply for
up to six units, provides improved fault tolerance and
network uptime
• Multilevel security on console access prevents
unauthorized users from altering the switch configuration
• Support for TACACS+ authentication enables centralized
control of the switch and restricts unauthorized users from
altering the configuration
