SNMP Communities
This section of the Manager lets you configure and manage SNMP community strings, which identify
valid communities from which the SNMP server will accept requests. A community string is like a
password: it validates messages between an SNMP client and the server.
To use the VPN Concentrator SNMP server, you must configure and add at least one community string.
You can configure a maximum of 10 community strings. To protect security, the SNMP server does not
include the usual default
public community string, and we recommend that you not configure it.
