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
