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
|
|
