52.8 SNMP
Simple Network Management Protocol is a protocol used for exchanging management information
between network devices. Your ZyWALL / USG supports SNMP agent functionality, which allows a
manager station to manage and monitor the ZyWALL / USG through the network. The ZyWALL /
USG 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.
52.8.1 Supported MIBs
The ZyWALL / USG supports MIB II that is defined in RFC-1213 and RFC-1215. The ZyWALL / USG
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
ZyWALL / USG’s MIBs from www.zyxel.com.
52.8.2 SNMP Traps
The ZyWALL / USG 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
