Check the FAQ list of QSFPTEK real customers about the S7300 series enterprise switches. Hope it will help you know the campus switches better.


The QSFPTEK S7300 series switches are Carrier-level high-reliability and high-density aggregation routing switches, with full layer 3 functions. These series managed switches are designed for high-performance computing, high-end campuses, and data centers.


The S7300 series enterprise switches include three models: S7300-24X4C, S7300-48X2Q4C, and S7300-48TE4X2Q. The former two layer 3 switches are new-generation 10Gb ToR switches (top-of-rack switches) launched for high-performance cloud computing, data centers and high-end campus networks. S7300-24X4C is a 24 port 10G SFP+ switch while S7300-48X2Q4C is a 48 port 10Gb SFP+ switch. These fiber optic 10Gb switches with 10G SFP+, 40G QSFP+ and 100G QSFP28 ports, meet high-density 10G access and high-speed 40G/100G uplinks. Featuring up to 2.56Tbps switching capacity. 


The S7300-48TE4X2Q is a new-generation 48 port 2.5G access multi-gigabit switch, designed for the Internet cafe e-sports industry, large campus networks, and high-speed enterprise networks. The multigig switch meets the needs for 100M/1000M/2.5GBASE-T access and high-speed 10G/40G uplinks. This managed Ethernet switch delivers a switching capacity of 600Gbps and a forwarding rate of 360 Mpps for superior processing performance and network reliability.

To have you better understand the key features of S7300 series L3 switches, we list the most frequently asked questions (FAQ) from our customers below for your reference.

FAQ on QSFPTEK S7300 Series Ethernet Switches

Hardware Features

Q: Do these campus switches provide redundant power supplies and fans?

A: All three models of S3700 series switches are designed with power supply and fan redundancy. Based on Hitless Protection System (HPS), they are equipped with 1+1 modular hot-swappable power supplies and hot-swap 3+1 fans.


Q: I find all switches are AC-powered, can I custom DC-powered switches?

A: Yes. Although all S7300 series switches are equipped with dual default standard AC power supplies, they support custom DC power. Please contact your sales representatives and tell them you need DC-powered switches.


Q: What is the airflow direction of the S7300 series switches?

A: All S7300 series switches adopt front-to-back airflow. S5300 series switches use left-to-right airflow.

Software Features

Q: Do S7300 series switches stackable? How many can I stack switches as a unit?

A: It depends. S7300-24X4C and S7300-48X2Q4C support stacking, and S7300-48TE4X2Q is not a stackable switch. S7300-24X4C and S7300-48X2Q4C respectively allow up to 8 same models of switches to be interconnected over uplink ports and managed as a single virtual device. Switch stacking provides management and maintenance flexibility and future-proofs your network with scalability.


Q: What is BVSS Used For?

A: BVSS is a virtual switch system technology that can be viewed as switch stacking. It can virtualize multiple physical devices into one in logic, easily managing, configuring, and expanding your network.


Q: Can I configure LACP on S7300 series switches?

A: All three models are LACP switches, supporting LACP link aggregation. LACP link aggregation switch can enhance your link reliability and leverage bandwidth. 


Q: Do S7300 series switches support TRILL or VXLAN?

A: No, our S5300 and S7300 series switches are basic VLAN switches, and do not support Transparent Interconnection of Lots of Links (TRILL) or Virtual Extensible LAN (VXLAN). TRILL and VXLAN are similar protocols to address issues with large layer 2 networks, such as the need for scalability, high switching capacity, low latency, and redundancy. Please check our high-end S5600 and S7600 series switches, which support VXLAN.


Q: Do the S7300 series managed network switch support MLAG?

A: No. if you need MLAG for uninterrupted services, please quote for our high-end S5600 and S7600 series switches.


Q: Do S7300 series switches support IGMP?

A: S7300 series switch support rich IGMP protocols, including IGMP v2 snooping, IGMP v3 snooping, IGMP filter, and IGMP v1/v2/v3. The exact IGMP features of each model are shown in the table below.

IGMP v1/v2/v3


Q: Do S7300 series switches have encryption functions to secure authentication and MAC/IP security?

A: Yes, S7300 has perfect security authentication mechanisms, including IEEE 802.1x, Radius, Tacacs+, and SSH. Also, they support port isolation and port mirroring within the same VLAN, DHCP Snooping, DHCP Option 82 and IP + MAC + Port binding QoS. Port isolation addresses the application scenarios with high-security requirements, isolating the traffic among different end devices to control the users’ access.



Q: What does the encryption IEEE 802.1x used by the S7300 do?

A: QSFPTEK S7300 series switches adopt the port-based Network Access Control (PNAC) based on IEEE 802.1X. It provides an identification authentication mechanism to devices when required for accessing LANs or WLANs. This method can encrypt data and prevent large traffic attacks.

Q: Are the layer 3 managed switches configure-friendly? What management methods are supported?

A: Yes, these fully managed switches support Web, CLI, Telnet, SSH management, which are easy to configure for green-hand even without CLI expertise. Besides, S7300 is manageable through SNMP and RMON for flexible monitoring and maintenance in real-time. The exact management methods of each model are shown in the table below.
