ZyWALL (ZLD) CLI Reference Guide

This command sets a service control rule that allowed the computers with the IP addresses 
matching the specified address object to access the specified zone using FTP service.

This command displays FTP settings.

Simple Network Management Protocol is a protocol used for exchanging management information 
between network devices. Your ZyWALL supports SNMP agent functionality, which allows a manager 
station to manage and monitor the ZyWALL through the network. The ZyWALL supports SNMP 
version one (SNMPv1) and version two (SNMPv2c).

The ZyWALL supports MIB II that is defined in RFC-1213 and RFC-1215. The ZyWALL 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’s MIBs from 
www.zyxel.com.

The ZyWALL will send traps to the SNMP manager when any one of the following events occurs:

Router# configure terminal

Router(config)# ip ftp server rule 4 access-group Sales zone WAN action accept

Router# configure terminal

Router(config)# show ip ftp server status
