• 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
• Support for TACACS+ authentication enables
centralized control of the switch and restricts
unauthorized users from altering the configuration
• MAC-based port-level security prevents unauthorized
stations from accessing the switch
• User-selectable address learning mode simplifies
configuration and enhances security
• Multilevel security on console access prevents
unauthorized users from altering switch configurations
• IEEE 802.1D Spanning-Tree Protocol support for
redundant backbone connections and loop-free
networks simplifies network configuration and
improves fault tolerance
• Support for a redundant loopback cable connecting
the top and bottom switches in a GigaStack stack
• Support for optional Cisco Redundant Power System
300 (RPS 300) provides internal power supply
redundancy and resiliency
• Support for optional Cisco 300 watt redundant AC
power system provides a backup power source for up
to four units for improved fault tolerance and
network uptime
