SNMP
22.1
SNMP Overview
Simple Network Management Protocol is a protocol used for exchanging
management information between network devices. SNMP is a member of TCP/IP
protocol suite. A manager station can monitor the ZyXEL Device through the
network via SNMP version one (SNMPv1) and/or SNMP version 2c. The next figure
illustrates an SNMP management operation. SNMP is only available if TCP/IP is
configured.
