S5731-S24UN4X2Q 02354VCC 24*100M/1/2.5G Ethernet 4*10GE SFP+ Ports, 2*40GE QSFP Ports Managed Poe Switch

 Powerful Service Processing Capability and Multiple Security Control Mechanisms
 The CloudEngine S5731-S series next-generation Multi-GE Switches supports many Layer 2/Layer 3 multicast protocols such as PIM SM, PIM DM, PIM SSM, MLD, and IGMP snooping, to support multi-terminal high-definition video backhaul and video conferencing services.
 The CloudEngine S5731-S series next-generation Multi-GE Switches supports multiple Layer 3 features including OSPF,
IS-IS, BGP, and VRRP, meeting enterprises' requirements on access and aggregation service bearing, and enabling a variety of voice, video, and data applications.
 The CloudEngine S5731-S series next-generation Multi-GE Switches supports MAC address authentication, 802.1x
authentication, and Portal authentication, and implements dynamic delivery of policies (VLAN, QoS, and ACL) to users.
 The CloudEngine S5731-S series next-generation Multi-GE Switches provides a series of mechanisms to defend against DoS 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 change of the DHCP CHADDR value.
 The CloudEngine S5731-S series next-generation Multi-GE Switches sets up and maintains a DHCP snooping binding
table, and discards the packets that do not match the table entries.You can specify DHCP snooping trusted and untrusted ports to ensure that users connect only to the authorized DHCP server.
 The CloudEngine S5731-S series next-generation Multi-GE Switches supports strict ARP learning, which protects a
network against ARP spoofing attacks to ensure normal network access.
