Huawei S5700-28X-LI-24S-DC Switch Product Overview
Huawei S5700-28X-LI-24S-DC Switch is a simplified Gigabit Ethernet Switch with 24*100/1000 Base-X,4 of which are dual-purpose10/100/1000 or SFP,4 10 Gig SFP+ (10GE/GE auto-sensing) DC Power supporting RPS ( redundant power supply). The item is a next-generation energy-saving gigabit Layer 2 Ethernet switch and offers flexible GE access ports and extensive services. Bortset fra dem, this switch supports Ethernet Ring Protection Switching (ERPS), also referred to as G.• 8032. As the latest ring network protocol, ERPS was developed based on traditional Ethernet MAC and bridging functions and uses mature Ethernet OAM function and a ring automatic protection switching (R-APS) mechanism to implement millisecond-level protection switching. ERPS supports various services and allows flexible networking, helping customers build a network with lower OPEX and CAPEX. Derfor, Huawei S5700-28X-LI-24S-DC Switch provides customers with a green, let at administrere, let at udvide, og omkostningseffektiv gigabit til desktopløsningen.

Huawei S5700-28X-LI-24S-DC Switch Product Features
- Understøtter streng ARP-læring, som forhindrer ARP-spoofing-angreb, der udmatter ARP-indgange. Det giver også IP-kildetjek for at forhindre DoS-angreb forårsaget af spoofing af MAC-adresser, IP-adresse spoofing, og MAC/IP-spoofing.
- Providing multiple security measures to defend against Denial of Service (DoS) angreb, as well as attacks against networks or users. DoS attack types include SYN Flood attacks, Land attacks, Smurf attacks, and ICMP Flood attacks. Attacks to networks refer to STP BPDU/root attacks. Attacks to users include bogus DHCP server attacks, man-in-the-middle attacks, IP/MAC spoofing attacks, and DHCP request flood attacks. DoS attacks that change the CHADDR field in DHCP packets are also attacks against users.
- Supporting DHCP snooping, which discards invalid packets that do not match any binding entries, such as ARP spoofing packets and IP spoofing packets. This prevents hackers from using ARP packets to initiate man-in-the-middle attacks on campus networks. The interface connected to a DHCP server can be configured as a trusted interface to protect the system against bogus DHCP server attacks.
