Advanced QoS and traffic shaping: provides traffic prioritization using IEEE 802.1p Quality of Service (QoS) and Type of Service (TOS) with Differentiated Services Code Point (DSCP) and ingress/egress rate shaping to help ensure that critical time-sensitive traffic like voice receives the priority needed for quality communications

VLANs: segment the network by grouping users based on their data or traffic exchange requirements; help ensure improved use of available bandwidth as traffic flow is directed according to the needs of the business

Link aggregation (trunking): groups together up to 8 ports automatically using Link Aggregation Control Protocol (LACP), or manually, to form an ultra-high-bandwidth connection to the network backbone; helps prevent traffic bottlenecks

Selectable queue configurations: increase performance by selecting the number of queues and associated memory buffering that best meet the requirements of your network applications

Spanning Tree Protocol (STP/RSTP/MSTP): improves network compatibility, scalability, and availability

IGMP snooping: multicast filtering improves network performance, instead of flooding traffic to all ports

Unique voice features: automatic assignment of voice traffic separates VLANs (“auto-voice VLAN”); advanced voice QoS, traffic shaping, multicast filtering, and PoE support delivers the support necessary for quality voice communications

Fiber uplink: provides greater distance connectivity using Gigabit fiber uplinks

PoE support (PWR model only): provides power for IP phones, wireless LAN access points, and other IEEE 802.3af-compliant devices over the same cable used for data; lowers total cost of ownership because there is no need to run additional electrical wiring; supports prestandard PoE plus, allowing the switch to deliver up to 30 W of power

Resiliency and high availability

Spanning Tree/MSTP, RSTP, STP Root Guard: prevents network loops

8K MAC addresses: allows multiple Layer 2 devices to be networked through the switch

Layer 3 services
UDP helper function: allows UDP broadcasts to be directed across router interfaces to specific IP unicast or subnet broadcast addresses and prevents server spoofing for UDP services such as DHCP

ARP: determines the MAC address of another IP host in the same subnet; supports static ARPs; gratuitous ARP allows detection of duplicate IP addresses; proxy ARP allows normal ARP operation between subnets or when subnets are separated by a Layer 2 network

Layer 3 routing
