High availability
• 802.1w Rapid Recovery Spanning Tree allows subsecond failover to redundant link
• 802.1d Spanning Tree for loop free topology and link redundancy
• Fast forwarding mode on user ports to bypass 30 second delay for Spanning Tree
• Static and 802.3ad dynamic link aggregation supports automatic configuration of link aggregates with other switches (up to six aggregates with up to eight links per aggregate)
• Broadcast storm control
•
Quality of service
• 4 hardware queues per port and strict priority queue servicing to support mission critical applications
• Layer 2: SA/DA MAC/MAC Group, SA/DA VLAN, SA/DA slot/port/group, SA/DA Interface type
• Layer 3 (IP only): SA/DA IP address/group, Multicast address & Group (accept or deny), IP Protocol
• Layer 4: source/Dest TCP/UDP port & and TCP/UDP Protocol
• 802.1p stamping per port, TOS/DSCP stamping on a packet based on SA/DA (slot/port, IP address, IP protocol, L4 port)
• QoS remapping: 802.1p to 802.1p (per port only)
• IP-TOS to 802.1p (Global rule), DSCP to 802.1p (Global rule)
• Classification per port, 802.1p (CoS) value, MAC SA/DA, ToS precedence, DSCP value, IP SA/DA, TCP/UDP port
• 802.1p (CoS), ToS, DSCP marking to label mission critical packets with QoS information
• Egress flow-based rate limiting
Advanced security
• 802.1x industry standard port-based authentication challenges users with a name and password before allowing network access
• Learned port security or MAC address lockdown allows only known devices to have network access, preventing unauthorized network device access
• RADIUS admin authentication prevents unauthorized switch management
• Secure Shell (SSH), Secure Socket Layer (SSL) and SNMPv3 for encrypted remote management communication
• Access control lists to filter out unwanted traffic, including denial of service attacks (ACLs per MAC SA/DA, IP SA/DA, TCP/UDP port)"
