[j-nsp] dosProtection

[Klenovszki, András]

Hi All,

As I have not too much experience in operating ERX devices I would appreciate your help.
We found log messages like this:

ERROR 02/17/2007 17:38:28 dosProtection: Flow is suspicious:
GigabitEthernet1/1.52.165206 for control protocol: IP TTL Expired current rate
151 pps

What does it exactly mean? What kind of traffic can cause this behaviour?
May it cause that certain customer experiences packet drops?

Thanks in advance!

Andras
