ROTOCOL

ONFIGURATION

Simple Network Management Protocol (SNMP) is a communication protocol

designed specifically for managing devices on a network. SNMP is typically

used to configure devices for proper operation in a network environment,

as well as to monitor them to evaluate performance or detect potential

problems.

The ADSL Router can be managed locally or remotely by SNMP.
