LAT Group codes and how to use them

see what groups the Vax is advertising services under

I check the mac address of the Vax host

Node Volatile Status as of 25-JUL-2000 11:39:12
 
Executor node = 3.2 (CHIP)
 
State                    = on
Physical address         = AA-00-04-00-02-0C

With lat enabled on the Cisco router, I check to see if I am receiving lat packets from the node

Yes I am, but I see no node record

Therefore I need to enable the commserver to respond to service group 43 or 73, because the vax is not advertising under group 0, (the default)

esc-3640-3#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
esc-3640-3(config)#lat group-list conrad 0 43
esc-3640-3(config)#line con 0

esc-3640-3(config-line)#^Z

And now I can see the service.

If I take off the lat-group for the console

esc-3640-3#
esc-3640-3#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
esc-3640-3(config)#line con 0

esc-3640-3#show lat servi

all the services have gone

If I modify the group list to ONLY include group 43, then only those nodes advertising group 43 are included
