For those with Enterasys experience, is there a way to set the device ID on=
 LLDP-MED to anything but the MAC address for a switch?

Thanks,
Brian

My boss asked me a question the other day, or more correctly expressed a de=
sire to be able to do something pretty specific.  He's tired of being told =
in casual conversation or in meetings that network performance was (usually=
) bad at a specific time (now), or more likely at a specific time 2 days ag=
o.  He, of course, asked me if there was any way we could determine this ki=
nd of issue across our whole network.

Our network is probably small compared to some of the campuses I've seen bu=
t still pretty sizeable (couple hundred switches).  So I wondered what othe=
r Network Managers do when this question is asked.  Typically if it is aske=
d in an immediate time frame, we scramble and send someone over to the loca=
tion and by the time we get there, everything is working just fine.  Even f=
or the person originally reporting the problem.  I know the typical answers=
 to these situations.

But I've been wondering if there is some way to keep data about performance=
 on a wide scale (and here's the hard part) without breaking the bank for s=
torage or processing (or software).  Is there anything that approaches what=
 I am looking for?  (and I'm sorry I can only describe it in such hand-wavy=
 terms)

I have heard about NetFlow but am not familiar with it.   I plan to investi=
gate it though. I was wondering if there was anything else capable of doing=
 something that approximates what I've  been asked to do?   (which seems pr=
etty much impossible to me right now)

Thanks.

Subject: Re: Detailed historical performance/monitoring.

What kind of performance are you looking to keep track of?  If you want
in/out statistics on switchports, check out Cacti.  It's free
(speech/beer) SNMP monitoring software based on rrdtool and will show
you traffic in/out, and can be set up for errors in/out as well (good
for autonegotiation mismatch diagnosis).  Obviously if you have a lot of
switches it'll take longer to set up, but once they're in there then
Cacti will just keep polling them and you can drill down into each
switch and check each or all ports on that device.  I usually would
check the port the user was on as well as the switch's uplinks.  Of
course the problem never was "the network", it turned out to be issues
with our Windows fileserver cluster, or Exchange bogging down for some
reason, etc.

Zabbix is also an option and can be used to track performance data using
SNMP and other performance tests. The data backend is not rrdtool like
Cacti but a full SQL database. It is extremely versatile.

On switchport stats, NeDi integrates with and complements Cacti.  It 1)
automatically discovers and graphs your switch's interfaces, cpu, memory,
and temp; 2) allows you to select which interfaces to tell Cacti to graph
with one click.

In this way you have a layered approach where NeDi graphs all interfaces
automatically as soon as a switch is discovered at low polling intervals
30-60 minutes (depending on your network size/discovery interval), and for
the important interfaces you can simply check a box in NeDi's list to have
that interface graphed in Cacti at high polling intervals (typically
5-minutes).  You may also put the Cacti graphs on a weathermap to display
your performance graphs in geographical or logical maps to have at-a-glance
views of what parts of your network are exceeding rate thresholds.
