I'm in the process of installing a Linksys SR2024. Is this -- or any --
switch capable of monitoring and logging transmission errors such as retries?
In other words, is there any way to monitor the switch and see, for example,
a connection problem that might start to show up as transmission errors?
Is this monitoring & logging capability available on less than the most
spendy models?
Thanks.

Switches come in 2 flavours: managed and unmanaged.
If you buy a managed switch, you can logon to it's console and
manage it. Which means a.o. see what happens and install or
enable trapping. (SNMP)
If you buy an unmanaged switch, the only serves the box provides
is 'switching'. (Although some manage to provide smoke signals if
something really goes wrong :-)

I haven't done this, but every OS can be set up to gather these
statistics and a Net Management app could pull these numbers. Setting
up ALL the machines would accomplsh what you seem to want. Microsoft
Net Manager, included in some Windows server kits and availalbel as a
stand-alone product can do this.
For Windows, every machine somes with PerfMon. Perfom is an
underapprciated tolll that can do lots to monitor all the counters on
the system and send alerts to a central server.
I'm a fan of simple managed switches and I like HP Procurve boxes.
Older ones are really cheap on Ebay and they have a lifetime warranty
so it's hard to go wrong. (RTFM, Some low-end models don't have
management.)

Actually, nowadays switches tend to come in three flavours, Unmanaged,
Web Managed and Managed. This is due to the artificially inflated
prices many manufacturers take for the "managed" switches.
The middle tier, often called "Web Managed", provides configuration
and often statistics via a Web interface and/or command line, but
doesn't do SNMP so it's much harder (or impossible) to do central
monitoring, alerting and management.
Also, some unmanaged switches used to be underprovisioned and many of
the small/cheap/less known brand "mini" switches (5/8-port) tends to
have unacceptable failure rates for a business net in my experience.
Web Managed can be a good choice especially for smaller networks (one
or two switches) where central management & monitoring is much less
likely to be in place (and/or a major factor).
It really shouldn't cost much to add the SNMP capabilities to get to
"Managed", most of cost is a "sunk" cost for the initial software
development... But those switches can be priced based on the extra
value they bring to someone with more switches.
Personally I'm wary of the Linksys and D-Link "business" switch, even
if people do report that they're somewhat less flaky than their
consumer units.
So far I've always found gear from bigger network hardware
manufacturers I've used before at similar price points (HP, know less
about SMC but what I've seen looks good. OTOH CERTAINLY *not* 3Com,
still has the scars from those), so I've seen no need.
Cisco equipment works, but is a lot more expensive and you need an
active support contract to get software (except security fixes, which
is pretty rare on the L2 side).
