Cisco Filter Network Mask

1.3.6.1.4.1.9.9.474.1.1.2.1.4

This is the wild card mask for the cfgFilterNetworkAddress bits that must match. Presence of 0 bits in the mask indicate that corresponding bits in the cfgFilterNetworkAddress 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 and destination address the same as cfgFilterNetworkAddress to match. This object value has to be consistent with the type specified in cfgFilterNetworkAddressType.
