• Secures a port to an individual MAC address group of
up to 132 MAC addresses; addresses can be learned or
manually entered; can prevent unauthorized stations
from accessing the switch.
• Password-protected in-band and out-of-band
management provides protection against unauthorized
configuration changes and secures against unwanted
intruders. Provides administrators the choice of level of
security, notification, and resulting actions.
• TACACS+authentication enablescentralized control of
theswitchandrestrictsunauthorizedusersfromaltering
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.
• Support for the optional Cisco 600-watt redundant
AC power system provides a backup power source
for up to four units for improved fault tolerance and
network uptime.
• Multilevel security on the console access prevents
unauthorized users from altering the switch
configuration.
• Cisco Uplink Fast technology ensures quick failover
recovery, enhancing overall network stability and
reliability.
• Cross-stack Uplink Fast (CSUF) technology provides
increased redundancy and network resiliency through
fast spanning-tree convergance (less than 2 seconds)
across a stack of switches using Gigastack GBICs.
• Redundant stacking connections support a redundant
loopback connection in top and bottom switches in
a stack.
• Command Switch Redundancy allows customers to
designate a backup command switch, which takes over
clustermanagement functionsin theeventof afailure of
the primary command switch.
• Unidirectional Link Detection (UDLD) detects and
disables unidirectional links caused by incorrect wiring
or interface faults, preventing Spanning Tree loops.
