SNMP (Simple Network Management Protocol) is a standard network management protocol used on TCP/IP networks. It supports batch network device management and implements unified management in spite of different device types (such as network switches, routers and firewalls) and different vendors. FS 3900 series high-performance Gigabit Ethernet L2/L3 Lite managed switches are suitable for home use, SMB (small and medium business), enterprise and campus networks. They support SNMP to offer simplicity and power for network management.
Connect one S3900 network switch to the NMS (network management station) via any port. SNMP communication is achieved by configuring NMS program on NMS side, and configuring agent on the network switch. NMS can get the status of S3900 switch by sending requests to agents and then control the devices remotely. And the agent can report the status and fault of the switch to the NMS in real-time.
Note that, there are three versions of SNMP, including SNMPv1, SNMPv2c and SNMPv3.
SNMPv1 was first defined in 1990, operating within the structure management information specification, and described in RFC 1157.
SNMPv2, defined by RFC 1411 and RFC 1452, improves SNMPv1 by adding further protocol operations and data types and providing security. However, SNMPv2 is not widely adopted because its security system is considered by many IT persons as overly complex. SNMPv2c, defined in RFC 1901-RFC 1910, improves error handling and SET commands compared to the previous versions. SNMPv2c is widely viewed as the de facto SNMPv2 standard.
SNMPv3 is introduced in RFC 3410, which adds security and remote configuration enhancements.
FS S3900 series switches support SNMPv1, SNMPv2c and SNMPv3, improving network administrators work efficiency and reduce management costs.
S3900 series switches consist of S3900-24F4S, S3900-24T4S, and S3900-48T4S. All three switches support SNMP. Any 100/1000Base-T port can be connected to the NMS by an Ethernet cable. But note that, S3900-24F4S switch is designed with 20x 1000Base-X SFP ports, 4x 1 Combo SFP ports and 4x 10G SFP+ ports. If one needs to use the SFP port to connect the NMS, 1000Base-T transceivers should be used on the 1000Base-X SFP ports or Combo SFP ports to connect S3900-24F4S and the NMS via Ethernet cables.
Successful configuration of running SNMP on S3900 series switches can be achieved via CLI commands. There are mainly three steps to configure SNMP on S3900 series switches.
Configure IP address.
Configure the access rights
S3900-24F4S(config)#interface vlan 1
S3900-24F4S(config-if)#ip add 192.168.2.1 255.255.255.0
S3900-24F4S(config)#snmp-server contact FS.COM
S3900-24F4S(config)#snmp-server location New Castle
S3900-24F4S(config)#snmp-server community public ro
S3900-24F4S(config)#snmp-server community private rw
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
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
I'm currently evaluating your products for our own infrastructure. I think that your S3900-24T4S could be a good solution for our needs. I need 8 switch to popolate our racks and providing access connectivity to our servers. The main issue is that I also need 2 core switch for connecting the access layer each other and uplink to the network perimeter. I've not found in your catalog a switch model that couldd be used for this scope.We have in plan to upgrade the network with more advanced features in the next future so, for now, I'm investigating the market for an affordable solution. I'm evaluating ubiquity products becaue this vendor has a 12 SFP+ ports available in its catalogue. By Popovich on June 9, 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
Does the QinQ function of S3900 series switches support no vlan tags or add double vlan tags? By Jamange on June 9, 2020
The S3900 series switches don't support no vlan tags or add double vlan tags yet, but the S58 series switches support these. For more information, please feel free to contact email@example.com. By FS on June 9, 2020
After the switch is configured with sflow function, the configuration file will not display the sflow configuration. When you check the Sflow configuration command, it will show sFlow. By FS on June 8, 2020
