KEY FEATURES SUMMARY CONTINUED

Denial of Service Protection—Monitoring, throttling, and locking out of ICMP and TCP SYN

trafc both to the management address of the switch and for transit trafc

Man-in-the-Middle prevention using Dynamic ARP Inspection and DHCP Snooping*

Port Security and MAC Address Locking limits the number MAC addresses learned

on a port. Using Port Security network managers can allow specic MAC addresses

access to the network for specic time periods.

MAC address authentication including multiple device authentication and dynamic

policy conguration

Policy-controlled MAC-based VLANs provide additional control

Advanced Quality of Service

Packet classication, reclassication, policing, marking, and re-marking

Identication, classication, and reclassication of trafc based on specic criteria

such as port, source/destination MAC address, 802.1p priority bit, source/destination

IP address, Type of Service (ToS), Differentiated Services Codepoints (DSCP), or

TCP/UDP port

Flexible queue servicing utilizing congurable Weighted Round Robin (WRR), Strict

Priority (SP), or hybrid SP/WRR

8 hardware queues for exible QoS management

Ingress rate limiting—standard and extended ACL control

ACLs congured on a per-port per-VLAN basis

Egress rate limiting—per-port, per-queue

Support for up to 256 wire-speed ingress trafc policers with each policer supporting

congurable metering with maximum and burst size settings, color aware and out-of-

prole packet remarking or dropping sFlow and port mirroring on the same port

System and Network Resilience

Advanced Layer 2 service protection features: Metro Ring Protocol (versions I and II),

Virtual Switch Redundancy Protocol, Rapid Spanning Tree, Multiple Spanning Tree, Per

VLAN Spanning Tree (PVST, PVST+), Protected Link groups, Link Fault Signaling (LFS),

Remote Fault Notication (RFN)

Digital optical monitoring

Port range with port speed downshift and selective auto negotiation

Port loop detection to detect Layer 1/Layer 2 loops

Image checksum verication

Next boot information

Port ap dampening

Single link LACP as a standards-based bi-directional link detection protocol

Auto-conguration
