[mrtg] OFF-TOPIC: [maxbytes] for Cisco

[Reed Mohn, Anders]

Ahh..  this annoyed the **** out of me,
I used cfgmaker to get the config from a Cisco
router, and the BRI interface came back with maxbytes 8000,
while the Dialer interfaces mapped on to it came back with 7000.
I couldn't figure out why until I had a closer look at the router.

Can anyone tell me whether this is just a default thing in Cisco?
(or is there another reason for it?)
AFAIR, the dialer IF's were not specifically configured to be 56k,
but "show interface" clearly states 56k...

Cheers,
Anders RM :)

This has just recently been discussed.
The MaxBytes setting comes from the device itself.  If the
device reports 8012 Bps (strange value BTW) then 8012 it is.

The proper way is to make a change on the device.  This may not
be possible.  In that case there is not much you can do apart
from altering the cfgmaker output.

In stead of manually altering it, you could write a script that
filters the output of cfgmaker thereby changing those values.
This is useful if you recreate your config file frequently.

cheers,
