Solved: Will updating my IPS license on a 5520 interrupt traffic?

I need to update my IPS licenses and didn't know if doing this would cause a traffic interruption or require a reboot to the IPS? Thanks, Tony

Yes, you can apply and/or upgrade a license on a running sensor without interupting traffic. Signature updates and Service Packs DO interupt traffic if your IPS is in-line.

No, the license is only checked when the sensor attempts to apply a signature update. If the sensor does not have a valid license, the update is not applied. The sensor will still perform as normal, with no interuption in operations, aside from having stale signatures.

So I have 2 IPS modules to update the license on, one with a current license that will expire in November, and one that doesn't have a license at all, to which I have been assigned a trial license until Cisco completes the license agreement and assigns the permanent one.

Either way, I can either update or apply the trial license without interrupting traffic?

Also, when an updated signature is applied, does that affect traffic?

Thanks for the help, Tony
