Help,
    
1.	On one of my DECbridge 610 bridge ports (line 4), I have a need to 
	only allow certain static and multicast address to pass, so I need
	to use manual mode.  As soon as I set line 4 manual mode = true,
	all Ethernet lines stopped forwarding packets.  I tried to  reverse 
	the situation by setting the manual mode = false, although the command
	was successful, it didn't not fix the problem.  I had to reset the 
	bridge in order to get operations back to normal.  Why does setting 
	manual mode = true have this effect?  It shouldn't.

2.	I thought that maybe that it was a bug and I could get around it
	by leaving the port set with manual mode = true and reboot the
	bridge.  I tried it, and it sort of worked.  After the bridge came
	up line 1, 2, and 3 were forwarding properly, but line 4 was not 
	allowing a session across itself, even though I had explicitly entered 
	the nodes addresses as static entries with forwarding maps to all ports.
	I am certain that the static entries I had entered should have worked,
	because I have the same setup with a LANbridge 200 (set up using ELMS)
	and it works fine.  Why doesn't this work?

3.	Discouraged, I continued to to try more static entries, and double
	checked them with show commands.  They all showed to be set properly
	as permanent = true , management set, forward map from all ports to all 
	ports, etc.  As I was typing one of the create commands, the bridge 
	rebooted itself.  All of the self-tests passed, and I was soon online 
	again.  

4.	Then I looked around for a while.  I noticed that the permanent static
	entries that I had set were no longer there.  Why are permanent static
	entries disappearing?  BTW: the defaults dip switch is disabled.

5.	I decided to forget about trying to deal with all these problems, and	
	set line 4 manual mode = false.  As a result, the bridge stopped
	forwarding packets on all Ethernet lines just like problem 1, except 
	this time I was disabling manual mode instead of enabling it. Why?
