Change Community String
This function can let you change the community string to the AP. You can
change a new community string on purpose to prohibit other AP Manager
access and manage your AP. After you change the community string to AP,
you need to do two following actions.
1. Use Password->Set Community String on the Menu Bar to set the
community string to the AP manager. The AP Manager and the AP
should have the same community string. Otherwise the AP Manager
will not be able to find the AP with different community string.
2. Please memorize the community string or write it down at
somewhere.
In case you forget the community string, you have to press the AP init button
and then the AP setting (include community string) will be restore to default
value.
Note: The SNMP community string defines the relationship between an
SNMP manager system (AP Manager) and the agent systems (all
APs). This string acts like a password to control the AP Manager to
access the AP. The default value of the community string is "public"
You can change the community string of AP Manager by using
Password->Set Community String on the Menu Bar.
