Features and Highlights
Powerful Service Processing Capability
CloudEngine S5735-S supports a broad set of Layer 2/Layer 3 multicast protocols, such as PIM SM, PIM DM, PIM SSM,
MLD, and IGMP snooping. This capability is ideal for high-definition video backhaul and video conferencing access.
CloudEngine S5735-S provides multiple Layer 3 features including OSPF, IS-IS, BGP, and VRRP, meeting enterprises'
access and aggregation service needs and enabling a variety of voice, video, and data applications.
Multiple Security Control Mechanisms
CloudEngine S5735-S supports MAC address authentication, 802.1X authentication, and Portal authentication, and
implements dynamic delivery of policies (VLAN, QoS, and ACL) to users.
CloudEngine S5735-S provides a series of mechanisms to defend against DoS attacks and user-targeted attacks. DoS
attacks are targeted at switches and include SYN flood, Land, Smurf, and ICMP flood attacks. User-targeted attacks include
bogus DHCP server attacks, IP/MAC address spoofing, DHCP request flood, and changing of the DHCP CHADDR value.
CloudEngine S5735-S sets up and maintains a DHCP snooping binding table, and discards the packets that do not match
the table entries. The DHCP snooping trusted port feature ensures that users connect only to the authorized DHCP server.
CloudEngine S5735-S supports strict ARP learning, which protects a network against ARP spoofing attacks to ensure that
users can connect to the Internet normally.
Multiple Reliability Mechanisms
CloudEngine S5735-S is equipped with two pluggable power modules that work in 1+1 redundancy backup mode. Mixed
installation of AC and DC power modules is supported, allowing for flexible configuration of AC or DC power modules according
to service requirements.
In addition to supporting traditional Spanning Tree Protocol (STP), Rapid Spanning Tree Protocol (RSTP), and Multiple
Spanning Tree Protocol (MSTP), CloudEngine S5735-S is also designed with Huawei-developed Smart Ethernet Protection
(SEP) technology and the industry's latest Ethernet Ring Protection Switching (ERPS) technology. SEP is a ring protection
protocol specific to the Ethernet link layer, and applies to various ring network topologies, such as open ring topology, closed
ring topology, and cascading ring topology. This protocol is reliable, easy to maintain, and implements fast protection switching
within 50 ms. ERPS is defined in ITU-T G.8032, and it implements millisecond-level protection switching based on traditional
Ethernet MAC and bridging functions.
CloudEngine S5735-S supports Smart Link, which implements backup of uplinks. One CloudEngine S5735-S switch can
connect to multiple aggregation switches through multiple links, significantly improving reliability of access devices.
CloudEngine S5735-S supports Ethernet OAM (IEEE 802.3ah/802.1ag) to fast-detect link faults
