I'm looking for recommendations with respect to a Local Area Network
analysis and troubleshooting tool. My network is thick ethernet, with
three separate networks joined by routers. The majority of the systems
are SUN, with a few DEC and other brands all running TCP/IP protocols.
Total number of nodes is about 100. 

I'm not nearly as concerned with protocol or software-related problems
as I am with physical layer problems. **** I am especially interested in
being able to efficiently locate hardware-related problems which are
causing excessive collisions or other symptoms associated with degraded
network performance.**** Other net management capabilities of a tool are
nice, but my primary concern is being able to locate
other-than-disastrous problems without having to make the network
unavailable to the users. (For example, I have a cable tester which is
good in case of a decisive failure, but even if it were useful for
troubleshooting lesser problems, I can't use it unless I'm the only one
using the network). Nor is it usually practical to go around 
disconnecting nodes from the net in order to observe the differences
in network performance.

I will summarize the responses. Thank you.
