This read-write DisplayString holds the actual filter definition, a set of criteria that either prevents extraneous frames from being forwarded or sends specific frames over the high- or low-priority bridge channel of the composite link, the latter used to prioritize a particular traffic type over the Bridge 1 channel. It is where the administrator encodes the concrete match criteria, such as address or protocol patterns, that this filter entry applies. For example, an administrator wanting to give SNA traffic priority over the composite link's Bridge 1 channel would encode a matching criterion in this object that directs frames matching that traffic type to the high-priority channel.
