Features and benets
Quality of service (QoS)
• Trac prioritization (IEEE 802.1p)
Allows real-time trac classication into eight priority levels that are mapped to eight queues
• L4 prioritization
Enables prioritization based on TCP/UDP port numbers
• Class of service (CoS)
Sets the IEEE 802.1p priority tag based on the IP address, IP type of service (ToS), L3 protocol,
TCP/UDP port number, source port, and DiServ
• Rate limiting
Establishes per-port ingress-enforced maximums and per-port per-queue minimums
• Large buers
Provide graceful congestion management
Connectivity
• Flexible 10 Gb/s Ethernet connectivity
Up to four optional 10 Gigabit ports (SFP+ and/or 10GBASE-T)
• Optional two-port stacking module with up to 40 Gb/s per port
Allows stacking of up to four switch units into a single virtual device
• Auto-MDIX
Provides automatic adjustments for straight-through or crossover cables on all 10/100 and
10/100/1000 ports
• IPv6
– IPv6 host
Allows the switches to be managed and deployed at the edge of IPv6 networks
– Dual stack (IPv4/IPv6)
Provides the transition mechanism from IPv4 to IPv6; and supports connectivity for both
protocols
– MLD snooping
Forwards IPv6 multicast trac to the appropriate interface; and helps prevent IPv6 multicast
trac from ooding the network
