Huawei S12700 Series agile core switches have a fully programmable architecture to best meet fast-changing service needs, allowing new services to be flexibly and quickly provisioned within six months. The series provides high-performance Layer 2 and Layer 3 switching services, supports millions of hardware entries, and meets campus network evolution needs over the next ten years. Built-in, large capacity Wireless Local Area Network (WLAN) Access Controller (AC) functionalities achieve wired and wireless convergence, eliminating the capacity bottleneck associated with ACs.

S12704 FAQ
Q1: How many service boards does it support? Is it compatible with future upgrades?
A1: It supports a maximum of 8 service boards, compatible with 40G/10G service boards, and has reserved upgrade interfaces to cope with bandwidth growth over the next 2-3 years.
Q2: Will redundancy switching affect services?
A2: Switching time is <50ms, imperceptible to terminals, and has no impact on critical business operations such as office work and production.
Q3: What are the differences between it and the S12708?
A3: Focused on small to medium-sized scenarios, it offers more streamlined expansion in terms of quantity and capacity, and a more competitive price, making it suitable for users who do not require large-scale expansion.
