Traffic Stops after 10-15 minutes after IPS put inline

[randyclark]

I put our 4250 inline with our PIX using the interfaces setup as pairs. The IPS was set to take no action on all sigs. After about 10-15 minutes traffic to the PIX stopped from inside and I had to move back to the oringal port. The PIX is on it's on vlan. The IPS port on the switch side was set to the same vlan as the PIX. Port speed and duplex was hard coded on all interfaces. No errors on any of the ports. The setup was like this

Inside switch (vlan 10)--IPS---PIX---Internet.

Why did the traffic stop???

Hi Randy:

Is hard to imagine what could be happen, but I suggest you take a look in the event log to see what was the last event logged.

Perhaps it get you a clue.

I hope this help (please rate if it does)

Best regards.

I suggest you take a look in the switch event log too.

Perhaps was an STP problem (it blocked the port).

Good luck

The IPS appears to be fixed. I had to remove the GX fiber card and now the sensor passes traffic without fail. The Cisco TAC said they knew of no known issues with the two cards.
