There is an issue with the script used for the Traffic Intelligence (CEC (Classification Engine Core)) Hitless Upgrade that misses installing on some blades during install/deploy on VIPRION systems. Symptoms include: -- POST error in the GUI. -- Automatic classification updates are downloaded successfully, but downloaded packages disappear after some time if you do not proceed to install/deploy.


Unable to auto-update Classification signature package on all slots, because the slot count reported for CEC is 0. These packages are installed only on the current slot.


-- CEC hitless update. -- Using VIPRION chassis.


Install the package manually on each slot. Note: When you refresh the GUI page, the downloaded package appears in the 'Available to Install' list, and you can proceed to install on each slot.
