2. (Optional) In the Name box, select a different community to edit.
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 Result
10.40.166.87
255.255.255.255
Allows access only from 10.40.166.87
10.40.166.87
10.40.166.87
Allows access only from 10.40.166.87
10.40.166.87
10.40.166.0
Invalid because the logical bitwise operation (address AND mask)
is not equal to the address
10.40.166.87
255.255.0.0
Invalid because the logical bitwise operation (address AND mask)
is not equal to the address
10.40.0.0
255.255.0.0
Allows access from any client with address 10.40.xx.xx
Additional Information
l 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.
