- Flow-based packet classification (classification based on information in
the MAC, IP, and TCP/UDP headers) for high-performance QoS at the
network edge, allowing for differentiated service levels for different
types of network traffic and for prioritizing mission-critical traffic in the
network
- Support for IEEE 802.1p CoS scheduling for classification and
preferential treatment of high-priority voice traffic
–
Egress policing and scheduling of egress queues – four egress queues on
all switch ports; support for strict priority and weighted round-robin
(WRR) CoS policies
– Source IP/Destination IP (SIP/DIP) address routing.
v
Monitoring
– Switch LEDs that provide visual port and switch status
– SPAN/RSPAN support for local and remote monitoring of the network
– Four groups (history, statistics, alarms, and events) of embedded remote
monitoring (RMON) agents for network monitoring and traffic analysis
– MAC address notification for tracking the MAC addresses that the switch
has learned or removed
– Syslog facility for logging system messages about authentication or
authorization errors, resource issues, and time out events
– Layer 2 trace route to identify the physical path that a packet takes from a
source device to a destination device
