Simple Network Management Protocol (SNMP) is an OSI Layer 7 (Application Layer) protocol designed
specifically for managing and monitoring network devices. SNMP enables network management stations to
read and modify the settings of gateways, routers, switches, and other network devices. Use SNMP to
configure system features for proper operation, monitor performance and detect potential problems in the
Switch or LAN.
Managed devices that support SNMP include software (referred to as an agent), which runs locally on the
device. A defined set of variables (managed objects) is maintained by the SNMP agent and used to manage
the device. These objects are defined in a Management Information Base (MIB), which provides a standard
presentation of the information controlled by the on-board SNMP agent. SNMP defines both the format of the
MIB specifications and the protocol used to access this information over the network.
The default SNMP setting is disabled. Click Enabled to set Community Settings and then Apply.
Community Setting: In support of SNMP version 1, the Web-Smart Switch accomplishes user
authentication by using Community Settings that function as passwords. The remote user SNMP application
and the Switch SNMP must use the same community string. SNMP packets from a station that are not
authenticated are ignored (dropped).
The default community strings for the Switch used for SNMP v.1 management access are:
Read_Only: The community with read-only privilege allows authorized management stations to retrieve MIB
objects. The default name is public.
Read_Write: The community with read/write privilege allows authorized management stations to retrieve and
modify MIB objects. The default name is private.
Trap Setting: Traps are messages that alert network personnel of events that occur on the Switch. Such
events can be as severe as a reboot (someone accidentally turned the Switch OFF), or less serious events
such as a port status change. The Switch can generate traps and send them to the trap recipient (i.e.
network administrator).
Setting up a Trap: Select Enable, enter a Trap Name, add the IP of the device to be monitored, and select
the event(s) to trap. The available trap Events to choose from include:
SNMP Authentication Traps
System Device Bootup
Fiber Link Up / Link Down
Twisted Pair Link Up / Link Down
RSTP Port State Change
Firmware Upgrade State
