2 Enter a unique Name (up to 20 characters). Valid characters are
letters, numbers, hyphens, and underscores.
Caution: If no communities are defined, the SNMP agent is not
accessible.
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
following table 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.
4 Select the Access Type for the new community:
• Get allows SNMP get operations.
• Get/Set allows both SNMP get and put operations.
