3 Enter a valid IP Address and Network Mask pair.
A pair is valid if performing a logical bitwise AND operation on the
IP address and the network mask results in the IP address. See the
table below for examples:
IP Address / Network Mask
10.40.166.87
255.255.255.255
10.40.166.87
10.40.166.87
10.40.166.87
10.40.166.0
10.40.166.87
255.255.0.0
10.40.0.0
255.255.0.0
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.
4 In the Access Type drop-down box, select the access type for the
community:
• Get - Allows SNMP get operations.
• Get/Set - Allows both SNMP get and put operations.
