Configure Subnet Ranges in SNMP Community

The SNMP system can dynamically originate SNMP GET requests from any host among a wide range of IP addresses. Due to the distributed nature of a typical network, the SNMP GET request may come from any IP address on an /8 netblock. It is not feasible to add all 16,777,216 possible IP addresses, one-by-one, to the snmp-community configuration. The solution for the Oracle® Enterprise Session Border Controller (E-SBC) is to allow subnet ranges in the snmp-community configuration. Such configuration allows the (E-SBC) to accept SNMP GET requests from any host in the specified subnet.

You can configure the subnet range from the ACLI and the Web GUI by way of the IP-addresses parameter in the snmp-community object.

The IP-addresses parameter accepts subnet addresses in address prefix format (<Net_addr>/<Net_mask>), for example, 10.0.0.0/24. For an exact match, omit the number of bits, for example, 10.196.0.0. For multiple entries, use the parenthesis separated by comma format, for example, (172.16.0.0/16,192.168.4.0/24).
