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
My account manager told me S3900 series switch only support stacking in the same model, and S3910 series switch support stacking in the same series By FS on September 9, 2021
How many switch stacks does it support? I will have a Ring link needs to be built By Schauer on August 23, 2021
It supports up to 6 Units (Same Models) stacking, two of my switches stacking are working well. By FS on August 23, 2021
Do you have a recommendation on which of the smaller models would be a good unit to test? For requirements I’d say nothing bigger than 24 ports and is managed. Layer3 isn’t a requirement. 1 or 10GB uplink. By Jeffrey Vogt on August 4, 2021
I think the S3900-24T4S can fully meet your 24 port requirements, and the 24 ports of this switch are all 10/100/1000M speed ports, which can be well connected to various wired terminals in your network. It also has 4*10Gb uplinks. By FS on August 4, 2021
Does S3900-24T4S support FS.com Extreme optics (10301-compatible)? By AFI.IT Dept on August 1, 2021
Yes, FS S3900-24T4S has a low compatibility restriction and Extreme optics will work on it. By FS on August 2, 2021
I tried it and it works. By FS on August 2, 2021
FS S39 series could support LACP and work across the stack. For example, the 2nd port of device 1 and 2nd port of device 2 could achieve LACP with the 3rd ports of device 3 & device 4, The prerequisite is that the stack of device 1 & 2 have been done. By FS on July 25, 2021
What's the advantage of fully managed switches compared with smart managed pro switches? By Phengie on July 19, 2021
One advantage I am aware of is that fully managed switches support Stacking or MLAG, but the smart managed pro switches do not. By FS on July 19, 2021
Are rack mount kits included on the switch #72944? By Guinn on July 18, 2021
I have purchsed this switch, and it includes rack mount kits. By FS on July 20, 2021
Can you give me a pointer on how to change that to 192.168.1.7 via the webinterface? By Demar on July 12, 2021
You can do it through CLI but not web, the command will be S3900-24T4S(config)#management ip address 192.168.1.7/24 By FS on July 12, 2021
We plan to install the switch in an open environment. We don't want to be bothered by the noise of the network switch, so silence is the most important thing. Any suggestions? By Bushnell on July 6, 2021
Recommended use #S3900-24T4S, Fanless, suitable for your use. By FS on July 6, 2021
