NOTE: When the Combo Gigabit Fiber port and the Copper ports
are both connected, the Fiber port will take precedence over the
Copper ports, meaning the Fiber port will be the only connection.
But, for 100M Fiber module, the Fiber port will not take precedence
over the Copper ports.
System > SNMP Setting
Simple Network Management Protocol (SNMP) is an OSI Layer 7
(Application Layer) 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.
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).
