Quality of Service and Class of Service
• IEEE 802.1p class of service (CoS) with two priority queues on the 10/100 and LRE switch ports
and eight priority queues on the Gigabit ports for prioritizing mission-critical and time-sensitive
traffic from data, voice, and telephony applications
• Voice VLAN (VVID) for creating subnets for voice traffic from Cisco IP Phones
Security
• Password-protected access (read-only and read-write access) to management interfaces (CMS and
CLI) for protection against unauthorized configuration changes
• Multilevel security for a choice of security level, notification, and resulting actions
• Dynamic address learning for enhanced security
• MAC-based port-level security for restricting the use of a switch port to a specific group of source
addresses and preventing switch access from unauthorized stations
• Terminal Access Controller Access Control System Plus (TACACS+), a proprietary feature for
managing network security through a TACACS server
Monitoring
• Switch LEDs that provide visual management of port- and switch-level status
• Switch Port Analyzer (SPAN) for complete traffic monitoring on any port
• Four groups (history, statistics, alarm, and events) of embedded remote monitoring (RMON)
agents for network monitoring and traffic analysis
• Syslog facility for logging system messages about authentication or authorization errors, resource
issues, and time-out events
