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

General
