docsDevFilterIpTos

This is the value to be matched to the packet's TOS (Type of Service) value (after the TOS value is ANDed with docsDevFilterIpTosMask). A value for this object of 0 and a mask of 0 matches all TOS values.

docsDevFilterIpTosMask

The mask to be applied to the packet's TOS value before matching.
