Feature	Benefits
Robust Power over Ethernet and VoIP	Standards-based IEEE 802.3af PoE supporting a wide variety of endpoints Independent system and PoE power subsystems allow the addition of PoE without affecting the system power High-availability power design—N+1 PoE power redundancy for B08S and B16S PoE auto-detection enables support for PoE and non-PoE devices without configuration changes Configurable per port PoE priority for power allocation Proven interoperability with popular Voice over IP equipment Advanced QoS and cell-based fabric enable high-quality VoIP service Auto-configuration for VoIP endpoints Voice VLAN feature automatically places IP phones in their own VLAN LLDP/LLDP-MED standards greatly simplify and enhance network management, asset management, and network troubleshooting
Advanced Security	sFlow®-powered automated closed-loop threat detection and mitigation solution Terminal Access Controller Access Control Systems (TACACS/TACACS+) and RADIUS operator authentication Secure Shell, Secure Copy, and SNMPv3 restrict and encrypt communications to the management interface and system IEEE 802.1x authentication including multiple device authentication and dynamic policy configuration for authenticated clients—VLAN and ACL Private VLANs provide security and isolation between switch ports to help ensure that users cannot snoop on other users’ traffic Denial of Service Protection—Monitoring, throttling, and locking out of ICMP and TCP SYN traffic both to the management address of the switch and for transit traffic IP Source Guard, DHCP Snooping, and ARP Inspection protect against snooping and man-in-the-middle attacks ACL-based Port Mirroring enables IP monitoring for CALEA and related law enforcement traffic monitoring Enhanced MAC filtering to include Denial of Service protection
Advanced QOS	Classification, reclassification, policing, and marking the traffic prior to delivery Identification, classification, and reclassification based on specific criteria (ACL-based) including port, source/destination MAC address, 802.1p priority bit, source/destination IP address, Type of Service (ToS), Differentiated Services Control Point (DSCP) fields, or the Transmission Control Protocol/User Datagram Protocol (TCP/UDP) port Flexible queue servicing utilizing configurable Weighted Round Robin (WRR), Strict Priority (SP), or combined SP/WRR Eight hardware queues for flexible QoS management Ingress rate limiting—standard and extended ACL control, per VLAN, per port Egress rate shaping per port
System and Network Resilience	Redundant, hot-swappable management modules Redundant, hot-swappable switch fabric Redundant, hot-swappable, load-sharing and distributed power supplies for system and PoE power Hot-swappable line modules Advanced protocols for topology resilience:
	Hitless Software Upgrade Hitless Controlled Switchover Brocade® Metro Ring Protocol (MRP) Virtual Switch Redundancy Protocol (VSRP) Protected Link Group
	Enhanced VRRP (VRRPE) Rapid Spanning Tree Protocol (RSTP) Multiple Spanning Tree Protocol (MSTP, 802.1s) Per-VLAN Spanning Tree (PVST/PVRST) BPDU Guard and Root Guard STP Protect IEEE 802.3ad (LACP) and static link aggregation
