There is a modeling upgrade requirement in the 10.2 Frequently Asked Questions to configure devices to utilize the LACP feature when upgrading to 10.2.
A. On each upgraded SpectroSERVER there is a script named RecreateLACPModels.pl in the <SPECROOT>/Install-Tools/PostInstall directory that you need to run. If you migrated your SSdb and need a copy of this script, contact CA Spectrum Support. This script only needs to be run on migrated or upgraded databases. It does NOT need to be run on brand new databases. After 10.2 has been installed, any newly created models that support LACP will have the functionality enabled automatically. A change has been made to work with PAgP configured LACP in 10.2. Refer to TEC1505504 and TEC1436634 as you may need to upgrade the firmware and/or add an entry to the <SPECROOT>/SS/.vnmrc file. If you already ran this script in 9.4.x or 10.0 and need the PAgP functionality, install 10.2, make the change to the .vnmrc, stop and restart the SpectroSERVER, and then run the script again.
