Chapter 3 Web Based Management

Please note the following when setting the Manager's IP:
1. Using the word 'default' will allow any IP address to manage the rack. They will be assigned the access
authority per the assigned community string and radio button setting, read-only or read-write.
2. When using the subnet delimiter (/8 /16 /24, etc.) the entire subnet can be allowed management rights.
3. When assigning only a single IP address for management, there is no need to use the /xx subnet.
The community strings act like passwords in dealing with the device via SNMP protocol. By changing the
community strings for read / write ('private' in these examples) and read only (public) access, and assigning a
community string to an access IP, an administrator can control access to the
FRM220 . Community string names
are case sensitive, therefore 'puBlic', 'Public' and 'public' are all different strings.
3.3.2.10 SNMP + Chassis / NMC Log
The NMC maintains a System Log buffer with the last 100 log messages. Each new message is assigned a
new and consecutive log number. The last 100 messages are available for view through the NMC Log page of the
Web interface.
Pressing the "Clear All" button will delete all of the displayed alarms and reset the Log number to one.
