Hello,
I have problem regarding TCP reset. I think I have the switch span configured
right as well as the IPS 4215. But the reset packet does not seem to get
through. When I issue the command below I have the 200 packets No Dest,
unicast and 200 Minimum size frames. Any body encountered the same problem?
When I choose alternate tcp reset interface it works.
IPS version is 6.0 and switches are 3550 with version 12.2(40)SE.
