I have 2 problem in IPS-4255-K9. my network has 2 device of IPS-4255-K9 and each have different problem
Problem no 1:
My IPS-4255-K9 after running for 1 hour or less than that starts to hang and all the traffic is blocked as it is inline mode.
Problem no 2:
My second IPS-4255-K9 after upgrading to 7.0 2 e4 engine from 6.0(5)E3 is working fine but have the problem in Sensor health. It does not change to yellow or red even after p2p bit torrent activity which is tracked in events status and it used to change before the upgrade. even for new signature update it not going to yellow. Any expect suggestion.
For your first issue, it would be best to open a service request with TAC so review of the output of a 'sh tech' command may be performed.
For your second issue, I am guessing that you are referring to "Network Security Health" and not "Senor Health". If you click the details link next to the "Network Security Health" dial, does it indicate there have been any red or yellow threats in the last five minutes?
