What is the difference between IP65 and IP66?
IP65 protects against low-pressure water jets, while IP66 protects against powerful, high-pressure water jets. The S5720I-SI is rated for the more demanding IP66 standard.
Is the S5720I-SI submersible?
No, it is not IP67 rated. While it is rugged for outdoor use, it is designed to withstand heavy rain and spray (IP66), not temporary submersion in water.
Huawei S5720-HI Agile Switch Features
What is the difference between Huawei S5720-EI and S5720-HI?
The S5720-EI (Enhanced) focuses on advanced Layer 3 routing and security features. The S5720-HI (High Intensity) is designed for agile campuses, supporting native AC, wired/wireless SVF, and free mobility out-of-the-box.
Does S5730-SI support wired and wireless SVF?
No, the S5730-SI (Standard) is an entry-level switch with basic features. It does not support the advanced SVF or native AC capabilities found in the HI series.
Huawei Agile Switches with Native AC and SVF Support
What is native AC in Huawei switches?
Native AC refers to the capability of a switch to function as an Access Controller for APs without requiring a separate physical AC appliance, reducing cost and complexity.
Do all S-series switches support wired and wireless SVF?
No. Only specific models like the S5720-HI, S6720-EI (with limitations), S7700, and S12700 support the full wired and wireless SVF feature set for unified management.
Why is S6720-SI incorrect for this question?
The S6720-SI is a Standard Intelligence switch lacking the advanced hardware and software licenses required for native AC and comprehensive SVF support found in higher-tier models.
S5730-SI vs S5720-SI Advantages Comparison
Does the S5720-SI support BGP?
Yes, the S5720-SI supports dynamic routing protocols including BGP, just like the S5730-SI.
What are the main hardware advantages of S5730-SI?
The S5730-SI offers pluggable dual fans, support for subcards, and higher density 40GE ports compared to the S5720-SI.
S5720-SI vs S5720-LI Feature Comparison
Does S5720-LI support OSPF?
No, the S5720-LI is a Layer 2 switch and does not support dynamic routing protocols like OSPF or BGP.
Do S5720-SI and S5720-LI have the same MAC table size?
Yes, both the S5720-SI and S5720-LI typically support up to 32,000 MAC addresses.
Huawei S6720 Maximum 10GE Port Density Verification
Which S6720 model has the most 10GE ports?
High-density fixed models like the S6720-54C-EI-48S provide 48 fixed 10GE SFP+ ports. Modular versions can exceed this further with additional interface cards.
Does the S6720 support modular expansion?
Yes, many S6720 chassis include slots for interface cards or uplink modules, allowing administrators to add more 10GE or 40GE ports beyond the base configuration.
