Nortel Ethernet Routing Switch 5510-48T + EU Power Cord AL1001B03-E5 用户手册

IPv6 filtering and classification support for future applications

BayStack 5510 Switches are able to identify, prioritize, classify, and redirect IPv6 traffic to a
router. These switches can address the need for larger addressing and tighter security as the
networks grow.

Jumbo frame support for larger file applications

Jumbo frame support of up to 9,216 bytes is provided on each port for applications requiring
large frames such as graphics and video applications.

The QoS features of the BayStack 5510 Switch allow users to not only utilize bandwidth
more efficiently, optimizing existing network resources and capabilities, but also provide
packet classification and marking at the edge of the network, simplifying the QoS deploy-
ment at the aggregation and core of the network. By classifying, prioritizing, policing, and
marking LAN traffic (based on DiffServ, Code Point, and 802.1p), networks can offer reliable
connectivity and required bandwidth for mission-critical applications, such as IP Telephony, to
specific groups, users, and individual devices.

For each of these applications, advanced QoS features support Internet Engineering Task
Force (IETF), the standard DiffServ QoS architecture—a packet classification based on the
content of IP packet header fields (voice, video, data)—as well as traffic policing.
