Symptom: When adding members to IPv4/IPv6 object-group, the following error appear for each member being added: !!% 'obj_group' detected the 'warning' condition 'Inconsistent address and prefix length. Address may not have bits set beyond prefix length. ' Conditions: The error is triggered by a prefix member, when any of the host bit is not zero. The host vs. network bits are pursuant to CIDR definitions. Example: 192.168.1.2/16, the "192.168.0.0" is network bits. "1.2" is the host bits. In this case, "1.2" is the problem because they are not zero. The acceptable config is: 192.168.0.0/16 Unless user applies caution, one can easily hit this error sooner or later. The problem is not about the error. The object-group feature requires all host bits to be 0. The problem is that when user types multiple prefix members, some have the non-zero host bits problem, while others do not have such problem, but the error appears for all members. It is therefore confusing to user exactly which member is the problem. The issue is confounded further when a large number of prefix members are being added
