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
