FS S3900 SERIES SWITCHES

Overview

The S3900 series switches consist of three models: S3900-24T4S, S3900-24F4S, S3900-48T4S, which are fully managed stackable Gigabit switches, equipped with Broadcom chips, supporting 10G SFP+ uplinks, designed for SMB, campus and enterprise networks.

SNMP Configuration on FS S3900 Series Switches

Posted on By FS.COM

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.

SNMP Application on S3900 Series Switches

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.

Hardware Connection for SNMP of S3900 Series Switches

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.

SNMP Configuration Roadmap of S3900 Series Switches

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.

  • Enable SNMP.

  • Configure the access rights

S3900 Series Switches SNMP Configuration via CLI

1. Configure an IP address for the PC.

IP address:192.168.2.100

Subnet mask:255.255.255.0

2. Configure an IP address of the switch interface to enable communication between the switch and PC.

S3900-24F4S#configure terminal

S3900-24F4S(config)#interface vlan 1

S3900-24F4S(config-if)#ip add 192.168.2.1 255.255.255.0

S3900-24F4S(config-if)#exit

3. Enable SNMP.

S3900-24F4S(config)#snmp-server server

4. Set admin identification and switch location.

S3900-24F4S(config)#snmp-server contact FS.COM

S3900-24F4S(config)#snmp-server location New Castle

5. Set the community read-only, and make the community read-write.

S3900-24F4S(config)#snmp-server community public ro

S3900-24F4S(config)#snmp-server community private rw

6. Note that, in this step, SNMPv2c is selected as the default version. And it’s backward compatible with SNMPv1. At last, choosing NMS software (not supplied with S3900 series switches) based on the actual networking needs (here uses MG-SOFT MIB Browser as an example), users can visit the configuration information of the switch.
