Generally, an ethernet LAN anaylzer and a protocol analyzer for serial lines
are different boxes.  I haven't seen any combined boxes, at least not any which
did either job real well.  I recommend you spend a lot of money on a good
LAN analyzer, and spend as little as you can for a serial line protocol
analyzer.

You will use the LAN analyzer all the time, and sometimes for hard problems.
On the other hand, you probably won't use the protocol analyzer nearly as much.
Furthermore, you probably won't rely upon the protocol analyzer as often.  I
don't have a cisco manual in front of me, but there may be enough traces
in the cisco to obviate the need for a high-power protocol analyzer.  I do,
however, like to see what is happening on the line, at least to the extent
of seeing flags and perhaps watching the cisco's try to bring the line up.
