cippfIpFilterSrcMask
Cisco IP Protocol Filter Ip Filter Src Mask
1.3.6.1.4.1.9.9.278.1.1.3.1.6
This is the wildcard mask for the cippfIpFilterSrcAddress bits that must match. 0 bits in the mask indicate the corresponding bits in the cippfIpFilterSrcAddress must match in order for the matching to be successful, and 1 bits are don't care bits in the matching. A value of zero causes only IP packets of source address the same as cippfIpFilterSrcAddress to match. This object value has to be consistent with the type specified in cippfIpFilterAddressType.
