879.2Address capture by port on DECrepeater 90'sNAC::FORRESTFri Apr 01 1994 21:1216
	Bob, I don't think this question has anything to do with DECagent 
	and HUBwatch rev levels. It depends more on what is being used to 
	query the DECrepeater 90C - DECbridge, DECagent V2.0, or DEChub 900 
	agent.

	The DECrepeater 90C (and 90T, 90FA, 90FL) captures the last source 
	address to come through on each port. It will report that address 
	if queried on the backplane for the last address.

	Alternatively, the 90C can be given an address and told to report 
	whether a match was found.

	So the answer depends on which module is hub bus master, and how 
	often it polls each slot and port. I'm not sure what the address 
	aging algorithm is that is used by each bus master.

    OOps.  I answered the wrong note.  My answer applies to note
    878 not 879.  Please ignore .1
