3.3.2.7 SNMP Setup<br />
3.3.2.8 Communities<br />
General Reference Guide <strong>eWON</strong> Configuration<br />
Figure 19: <strong>eWON</strong> SNMP setup main menu page<br />
The communities are defined here. These are acting like a "login-password" feature. Please refer to the SNMP standard for detailed explanations.<br />
Up to five different communities can be set up in the <strong>eWON</strong>. Each community has different read and write attributes. In the <strong>eWON</strong>, each of them<br />
can be specified for read and/or write rights. The standard public community is defined as read-only.<br />
3.3.2.9 Hosts<br />
The hosts that can access the communities and/or receive the generated SNMP traps have to be specified. If the checkbox Accept SNMP from<br />
any host is selected, any IP address will be granted to browse the SNMP tree of the <strong>eWON</strong>.<br />
The traps are always sent to know IP addresses defined in the following fields. Each host is determined by its IP address and by the community<br />
he is working on. For each host, the user can specify whether he can receive traps and/or browse the SNMP tree.<br />
A MIB file describing the SNMP structure and OID of the <strong>eWON</strong> is available on our web site.<br />
Traps can originate from three different events:<br />
System traps<br />
The parameters for Basic traps are as follows:<br />
At cold boot and at soft reboot, the <strong>eWON</strong> sends system traps with identification 0<br />
and 3 respectively.<br />
Basic scripting traps The sendtrap Basic function can send a trap at user request.<br />
Alarm event traps The <strong>eWON</strong> automatically sends a trap on alarm, containing alarm information.<br />
