Symptom
Console timeout value altered from default infinite (e.g. 0) to a different value. The running configuration of Lina will show that the value is still set at 0. This is a cosmetic issue and the true value from which console timeout is getting invoked is under /etc/sf/clish_attributes.conf (example below):
Changed timeout value to 10 minutes
