Huawei S2700-9TP-EI-AC 8×10/100 + 1×Gig Combo AC Ethernet Switch

Q1: What are the key characteristics of the S2700 series switches?

A: The S2700 are fanless, energy‑saving 100 Mbps intelligent switches based on Huawei’s VRP software. They support flexible VLANs, comprehensive QoS, ACLs, DHCP snooping, stacking (iStack), Smart Link/RRPP, and hardware security measures like surge protection.

Q2: Is the S2700 easy to install and manage?

A: Yes. It supports both CLI and Web GUI, with an easy‑operation mode that automates command synchronization, alarm monitoring, and visual configuration to simplify deployment .

Q3: What security features do S2700 switches offer?

A: They support DHCP snooping, IP source guard, ARP inspection, MAC‑binding, 802.1X/MAC authentication, ACLs (by VLAN, MAC, IP, protocol), and storm protection to prevent common network attacks .

Q4: How reliable are S2700 switches in enterprise networks?

A: They support iStack (virtual stacking), spanning tree (STP/RSTP/MSTP), ring protection protocols like SEP and G.8032, and link redundancy via Smart Link/RRPP for millisecond failover .

Q5: How do these switches manage traffic quality (QoS)?

A: S2700 switches implement eight queues per port and support WRR, SP, and WRR+SP scheduling. Traffic can be classified based on VLAN, MAC, IP, protocol, or TCP/UDP port for fine-grained control .

Q6: What energy‑saving features are included in the S2700?

A: They are fanless, use energy‑efficient designs, support idle port sleep mode, and meet low radiation standards—all delivering quiet, efficient operation .

Q7: Can the S2700 stack with other switches?

A: Yes, iStack lets you combine multiple S2700 units into one logical switch with unified management and single IP configuration .

Q8: How is VLAN configuration handled?

A: VLANs can be assigned by interface, MAC, protocol, or subnet. Dynamic VLAN propagation via GVRP reduces manual VLAN configuration .

Q9: What protections exist against lightning and surges?

A: S2700 series include patented surge protection circuits preventing lightning and high-voltage damage, even without separate grounding .

Q10: How does the S2700 handle ARP or DHCP attacks?

A: It supports DHCP snooping to block unauthorized servers and ARP inspection, while IP source guard and strict ARP learning defend against spoofing .

Q11: What are typical usage scenarios?

A: Ideal for enterprise access layers where dependable performance, security, energy efficiency, and quiet operation are required .

Q12: Are firmware updates and diagnostics available?

A: Yes. Huawei provides regular firmware updates, and the switches support health-check and alarm display via Console/Telnet, as outlined in the Quick Start guide .

Q13: Does the S2700 support out-of-band management?

A: Management can be done via console, Telnet, or SSHv2. The easy‑operation mode also supports web-based admin.

Q14: How should I troubleshoot the switch turning red on RUN indicator?

A: The RUN LED turning red indicates a boot failure or alarm condition—refer to the hardware FAQ for details .

Q15: Is Huawei’s S2700 series suitable for high‑density deployments?

A: As a 100 Mbps switch, it is best for smaller or legacy networks; high‑density Gigabit demands may require models like those in the S5700/S6700 series or newer CloudEngine lines .
