For Network Management purposes, IBM Firewall supports SNMP-based management. Packaged with the Firewall is a SNMP sub-agent that allows SNMP managers to monitor the firewall. Specifically, the sub-agent allows SNMP managers to access an IBM Firewall Management Information Base (MIB). Traps can be sent that report on critical system log activity and the status of important Firewall daemons. You can use the SNMP Subagent Configuration panel to configure key parameters for the subagent. You can also use this panel to start and stop the subagent.

The IP Address Mask is very much like a subnet mask. Bits in these masks that are set to 0 indicate the bit positions to be ignored during comparisons of IP Addresses. So, specifying 255.255.255.255 in the mask demands an exact match with the specified IP Address field, whereas a mask of 0.0.0.0 causes a match no matter what IP Address is specified.
