The S5700-SI supports wire-speed replication of multicast packets between VLANs, multicast load balancing among member interfaces of a trunk, and controllable multicast, meeting requirements for IPTV and other multicast services. The PoE+ function increases the maximum power of each port and implements intelligent power management for high-power consumption applications. These switches can be managed using a single IP address, which greatly reduces the costs of system expansion, operation, and maintenance.
The S5700-SI supports strict ARP learning, which prevents ARP spoofing attacks that will exhaust ARP entries. It also provides IP source check to prevent DoS attacks caused by MAC address spoofing, IP address spoofing, and MAC/IP spoofing. Users can manage the S5700-SI using the CLI and Web NMS. The NQA function helps users with network planning and upgrading. In addition, the S5700-SI supports NTP, SSH v2, HWTACACS+, RMON, log hosts, and port-based traffic statistics. Each port provides a maximum of 30W power, complying with IEEE 802.3at. Users can configure whether and when a PoE port supplies power. Easy deployment and maintenance free The S5700-SI supports automatic configuration, plug-and-play, deployment using a USB flash drive, and batch remote upgrade.
The S5700-SI supports a flow-based two-rate three-color CAR. Each port supports eight priority queues and multiple queue scheduling algorithms such as WRR, DRR, SP, WRR+SP, and DRR+SP. All of these ensure the quality of voice, video, and data services. Compared with traditional networking technologies, iStack has advantages in scalability, reliability, and system architecture. The S5700-SI supports 802.1x authentication, MAC address authentication, and combined authentication on a per port basis, as well as Portal authentication on a per VLANIF interface basis. Attacks to users include bogus DHCP server attacks, man-in-the-middle attacks, IP/MAC spoofing attacks, DHCP request flood attacks. DoS attacks that change the CHADDR field in DHCP packets are also attacks against users. The S5700-SI supports DHCP snooping, which discards invalid packets that do not match any binding entries, such as ARP spoofing packets and IP spoofing packets. The Commander can collect and display power consumption on the entire network.
