Layer 3
IPv4 routing: Wirespeed routing of IPv4 packets
Up to 990 static routes and up to 128 IP interfaces: IPv6 routing
Wirespeed routing of IPv6 packets: Layer 3 Interface
Configuration of Layer 3 interface on physical port, Link Aggregation (LAG), VLAN interface, or loopback interface: Classless Interdomain Routing (CIDR)
Support for classless interdomain routing: RIP v2
Support for Routing Information Protocol version 2 for dynamic routing: Policy-Based Routing (PBR)Flexible routing control to direct packets to different next hop based on IPv4 or IPv6 Access Control List (ACL): DHCP Server
Switch functions as an IPv4 DHCP server serving IP addresses for multiple DHCP pools/scopes: Support for DHCP options
DHCP relay at Layer 3: Relay of DHCP traffic across IP domains
User Datagram Protocol (UDP) relay: Relay of broadcast information across Layer 3 domains for application discovery or relaying of Bootstrap Protocol (BOOTP)/DHCP packets
Quality of Service
Priority levels: 8 hardware queues
Scheduling: Strict priority and Weighted Round-Robin (WRR)
Rate limiting: Ingress policer; egress shaping and rate control; per VLAN, per port, and flow based; 2R3C policing
Congestion avoidance: A TCP congestion avoidance algorithm is required to minimize and prevent global TCP loss synchronization
iSCSI traffic optimization: A mechanism for giving priority to iSCSI traffic over other types of traffic
Green (power efficiency)
Energy Detect: Automatically turns power off on RJ-45 port when detecting link down. Active mode is resumed without loss of any packets when the switch detects the link up
Cable length detection: Adjusts the signal strength based on the cable length. Reduces the power consumption for shorter cables.
EEE Compliant (802.3az): Supports IEEE 802.3az on all copper Gigabit Ethernet ports
Disable port LEDs: LEDs can be manually turned off to save on energy
Time-based port operation: Link up or down based on user-defined schedule (when the port is administratively up)
Time-based PoE: PoE power can be on or off based on user-defined schedule to save energy
