FAQ
There are usually multiple services such as IPTV, VoIP, and Internet access using different protocols in the LAN network. To facilitate network management, services using the same protocol are classified into the same VLAN for management. Thus there will be multiple protocol-based VLANs in one network. Processing data frames based on protocols such as IP, IPX, AT, etc, protocol-based VLAN is a VLAN that can only be configured in the hybrid interface to define filtering criteria for untagged packets. This article will focus on the protocol-based VLAN configuration on FS S3900 series switches which are designed for the campus network, SMB, and home network.
The following figure shows a typical protocol-based VLAN networking application of the S3900-24T4S managed switch. In the network, Internet services are provided through IPv4 and IPv6 protocols respectively. By configuring protocol-based VLANs on FS S3900-24T4S switches, the Internet services are divided into two different VLANs——VLAN 10 and VLAN 20. In VLAN 10, end-users communicate with the Internet server through the IPv4 protocol, while in VLAN 20, users use IPv6 to communicate.
Notes:
When receiving an untagged frame from a port, the switch will identify the protocol profile of the frame and then determine the VLAN that the frame belongs to.
If protocol-based VLANs are configured on the interface and the protocol profile of the frame matches a protocol-based VLAN, the switch adds the VLAN tag to the frame.
If protocol-based VLANs are configured on the interface and the protocol profile of the frame matches no protocol-based VLAN, the switch adds the PVID(Port VLAN ID) of the interface to the frame.
The protocol-based VLAN configuration of the S3900 series switches can be realized via the CLI interface. And the configuration process is suitable for all modes of S3900 series switches. Here take S3900-24T4S as an example.
Configure the IP address for the PCs.
Create the VLANs associated with each network layer protocol on the switches.
Configure the port type of the switch and allow the corresponding protocol VLAN to get through.
Verify your configuration.

Hi, is there a way to set a default gateway for the Management Interface - or is the accesss only possible from the same network Segment? By Sebastian.Schubert on October 19, 2020
Hello, the s3900 management port is not isolated from the service interface, so you only need to write a default route. For example: IP route 0.0.0.0 0.0.0.0 10.32.133.254 By FS on October 20, 2020
My switches are running the most recent release of the software available, but the ssh server implementation is so ancient that it cannot interoperate with even a four-year-old Ubuntu 16.04 client. When can this be fixed? By Garrett.Wollman on August 26, 2020
Hello, our switch supports ssh2.0, please describe in detail "the implementation of sh server is so old". Asymmetric encryption support: RSA1, DSA2 Symmetric encryption support: AES-128, AES-192, AES-256, 3DES, des_cbc, Blowfish HASH support: MD5, SHA1 By FS on August 27, 2020
After the S3900 switches are stacked, the device has lost the stacking port. What is the reason? By henson on June 19, 2020
After the S3900 switch is successfully stacked and you check the port status through the commands, the two stacking ports of the device will disappear which is a normal situation. It is mainly to prevent misoperation. Please don't worry. By FS on June 19, 2020
Why is the calendar set time of the switch restored after restarting? By Emoef on June 18, 2020
The time of calendar set is not saved in the configuration file so it will not continue counting after the device is turned off. It is recommended to use the ntp service to synchronize the system time, so that after the switch restarts, you only need to set the next restart time, and don‘t need to set the system time again. By FS on June 18, 2020
When multiple S3900 switches are stacked, one of them will go down. Will it affect the normal operation of other switches? By Soucie on June 16, 2020
If the master is down, it will re-elect, the election process is the same as the first stack. If it is a slave downtime, there will be no impact. By FS on June 16, 2020
Can the stacking and LACP functions of the S3900 be used together? By Helfer on June 15, 2020
Yes, after the S3900 switches are stacked, they are logically one device and can implement LACP with other devices. By FS on June 15, 2020
Hello, why do I fail to upload firmware to the S3900 switch when upgrading the switch? By Dennis Haislip on June 12, 2020
The S3900 series switches only support a maximum of 2 firmwares. Please use the command dir to check whether there are currently two firmwares. If so, you need to delete one and add the new one. If there is only one, please check whether the firmware is damaged. It is recommended to download and install again. By FS on June 12, 2020
Does the S3900 switch support https import certificates? By Shuford on June 11, 2020
Yes, but there are some requirements for the size of the certificate, the maximum is 5KB and the key is 2KB. By FS on June 11, 2020
When configuring QinQ, how many QinQ can be configured for each port? By Jimmina on June 10, 2020
The S3900 series are the access layer switches, which have certain restrictions on the hardware, so the maximum entry for QinQ is 24 per port. By FS on June 10, 2020
Hello, i see you need a solution for your network; our tech and salers can help you design your whole network solution with best quality and price. And we recommend the S3900-24T4S for you to connect to the server. The function of the core switch is more abundant than that of the access layer switch. So as for the core switch, we recommend S5800-8TF12S for the core switch. By FS on June 9, 2020
