What is nwAppnFwdIfCtrHostInBytes?

This read-only Counter reports the total bytes in Message Units delivered to local half sessions on this specific router port during the current operational window. Paired with this port's HostInMus counter, it reveals the average size of messages actually reaching the locally attached host on this link. An admin profiling one host's traffic pattern would look at this counter alongside HostInMus for that same port.
