Note: If you define a single community and set both the IP
address and network mask to 0.0.0.0 (or leave both blank),
then IP address-based access control is disabled. In this
case, the SNMP agent is accessible from any IP address.
Note: When entering IP addresses, never use an address that is in
a reserved IP address range. To see a list of reserved IP
address ranges, click the quick tip icon [?] located near the
IP address field.

community:
• Get - Allows SNMP get operations.
• Get/Set - Allows both SNMP get and put operations.
5 Select the Community status check box to enable the community.
Or clear the Community status check box to disable the
community.
