[mrtg] Re: Rmon

[R. Benjamin Kessler]

I believe the 2500's (and AS5200's) are the only platform to support
"Full RMON."  Most (all?) switches support "mini-RMON."

Mini-RMON consists of:

Statistics
History
Alarm
Event

The "full" RMON adds all of the other stuff in RFC 1757 (e.g. Packet
Capture, top talkers, etc.)

Most routers support Event and Alarm only - with this you can trigger
thresholds and send traps if they're crossed.

Router RMON is probably not going to be of much use to the MRTG set;
switch (mini-)RMON could be of use depending on what you're trying to
do.

HTH,

Ben

Recently, I was reading on the Cisco Website that only the 2500 series
routers supported RMON.

Pix doesn't support RMON. Cisco2600 might support it with the right
IOS image (Cisco2500 had such images) not sure if Cisco supports this.

My advice is to place an RMON probe on one of the inerfaces (PIX or
Cisco2600) and gain access to the probe through an interface that 
is not currently connected to the routing device (to avoid influence
on the real traffic from your polling of the probe).
