[cisco-bba] Fwd: Interface statistics

[Marko Pastric]

[UPDATE]

Hello,

The excessive traffic is coming from LACs (UDP/1701) and it's huge -
it almost doubles the users traffic (according to cumulative
virtual-access tx/rx rate).

Any feedback or figures would be great, since I'm (almost) certain
that this was not the case couple of weeks ago.


Regards,
Marko

Hello,

We have a standard 7200 series router acting as a LNS.  Now, in the
past few days there has been noticeable increase in bandwidth usage -
however, I can't find anything other than user generated (legitimate)
traffic.

Main question is: summaryzing the traffic rate on virtual interfaces
(with "show int summary") is almost 40% less than the rate showed on
the physical and/or logical interface. This has been double checked
using SNMP OID for both, sub- and physical interface. Mentioned
percent (from summary) is adequate to past usage, so this may be some
king of link saturation.


Have anyone had similar experience? NetFlow table is not showing any
excessive traffic - anything else that should be checked?


Regards,
Marko
