64.8 SNMP
Simple Network Management Protocol is a protocol used for exchanging management information
between network devices. Your Zyxel Device supports SNMP agent functionality, which allows a
manager station to manage and monitor the Zyxel Device through the network. The Zyxel Device
supports SNMP version one (SNMPv1) version two (SNMPv2c) and version 3 (SNMPv3).
SNMP v3 enhances security for SNMP management using authentication and encryption. SNMP
managers can be required to authenticate with agents before conducting SNMP management
sessions.
Security can be further enhanced by encrypting the SNMP messages sent from the managers.
Encryption protects the contents of the SNMP messages. When the contents of the SNMP messages are
encrypted, only the intended recipients can read them.
64.8.1 Supported MIBs
The Zyxel Device supports MIB II that is defined in RFC-1213 and RFC-1215. The Zyxel Device also supports
private MIBs (zywall.mib and zyxel-zywall-ZLD-Common.mib) to collect information about CPU and
memory usage and VPN total throughput. The focus of the MIBs is to let administrators collect statistical
data and monitor status and performance. You can download the Zyxel Device’s MIBs from
www.zyxel.com.
64.8.2 SNMP Traps
The Zyxel Device will send traps to the SNMP manager when any one of the following events occurs:
Router# configure terminal
Router(config)# show ip ftp server status
active : yes
port : 21
certificate: default
TLS : no
service control:
No. Zone Address Action
