• Domain Name Services (DNS) provide IP address
resolution with user-defined device names
• TFTP reduces the cost of administering software
upgrades by downloading from a centralized location
• Switch Cluster software upgrade allows network
administrators to upgrade the system software of up to
16 interconnected switches through a single CLI
command or through an easy-to-use CMS interface
• Network Time Protocol (NTP) provides an
accurate and consistent timestamp to all switches
within the intranet
• Multi-function LEDs per port for Port Status,
Half-Duplex/Full-Duplex, and 10/100/1000BaseT
indication as well as switch-level status LEDs for
System, RPS and Bandwidth Utilization provide a
comprehensive and convenient visual management
system
• VTP pruning limits broadcast on VTP trunks;
when VTP pruning is enabled, broadcast traffic is
flooded only on trunk links required to reach the
destination devices
Security and Redundancy
• IEEE 802.1x support (planned future
software support)
• Support for HSRP for Router Redundancy
• IEEE 802.1D Spanning-Tree Protocol support for
redundant backbone connections and loop-free
networks simplifies network configuration and
improves fault tolerance
• Cisco Uplink Fast/Backbone Fast technologies ensure
quick fail-over recovery enhancing overall network
stability and reliability
• Cross-Stack Uplink Fast (CSUF) technology provides
increased redundancy and network resiliency through
fast spanning-tree convergence (less than two seconds)
across a stack of switches using GigaStack GBICs
• Redundant stacking connections support for a
redundant loopback connection in top and bottom
switches in a stack
• Spanning Tree Root Guard (STRG) prevents edge
devices not in the network administrator’s control
from becoming STP root nodes
•
Bridge protocol data unit (BPDU)
guard prevents the
device from receiving spanning tree protocol BPDUs
• Data plane Access Control List to prevent
unauthorized data flows
• User-selectable address learning mode simplifies
configuration and enhances security
• Support for the optional Cisco Redundant Power
System 300 (RPS 300) that provides superior internal
power source redundancy for up to six Cisco
networking devices resulting in 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
• 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
• Local Proxy ARP works in conjunction with Private
VLAN Edge to minimize broadcasts and maximize
available bandwidth
