Default SNMP Community Strings
The AT-S106 Management software provides two default community
strings: public and private. The public string has an access mode of Read-
Only and the private string has an access mode of Read/Write. If you
activate SNMP management on the switch, you should delete or disable
the private community string, which is a standard community string in the
industry. Or, change the status of the community string from Read/Write to
Read which prevents unauthorized changes to the switch.
