networks (MANs), and can also be used for connecting server groups in data centers.

The feature-rich S5500-SI series switches support the following services:

z Broadband Internet access

z Access of MAN and enterprise network users

z Multimedia services, such as VoD

z Delay-sensitive voice services, such as VoIP

z Multicast audio and video services

S5500-SI series feature the following advantages:

z Providing full-Gigabit access ports

z Providing 10GE ports (except for the S5500-20TP-SI switch)

z Supporting IPv4/IPv6 dual-stack and hardware forwarding

z Supporting jumbo frames

z Supporting port security

z Supporting link aggregation control protocol (LACP)

z Supporting 4K VLANs

z Supporting QACL

z Supporting port-based/flow-based mirroring
