Brocade Network OS Software Licensing Guide v4.1.0 - Manual (Page 16)

configuration, the Dynamic POD configuration is moderated and restricted by whatever POD licenses
are present on the switch.
For example, if you download a configuration file from a switch that has POD assignments beyond the
base number of allowed Dynamic POD ports and there is no POD license installed, then the additional
ports beyond the number of ports in the base Dynamic POD set will not be allowed. When the
configuration is played back as part of the copy (or reboot) operation, the licenses are checked for
each additional Dynamic POD port that attempts to be assigned a reservation.
Upgrade and downgrade considerations
Downgrading from Network OS v4.1.0 to previous versions without a VCS Fabric license results in
loss of VCS functionality.
Downgrading from Network OS v.3.0.0 to a previous version is applicable only to the Brocade VDX
6710, VDX 6720, and VDX 6730, The VDX 8770 chassis only supports Network OS v.3.0.0. There are
no downgrade pre-installation requirements for any of the licensed features in Network OS v.3.0.0.
You cannot downgrade to Network OS v2.x when the switch is in Brocade VCS Fabric mode without
full POD licenses installed. Network OS v2.x requires full POD licenses to be installed when the switch
is in Brocade VCS Fabric mode.
If Dynamic POD reserve port configuration data is stored in the running-config file before you
downgrade to Network OS v2.x, restoring that running-config file after downgrade does not restore the
Dynamic POD reserve port information.
Obtaining a license
Use the following procedure to generate and obtain a software license.
1. Order a license for the desired licensed feature.
NOTE
To obtain a trial license, contact your Brocade representative.
2. When you receive the paperpack or electronic transaction key, retrieve the LID of your Brocade
device by entering the show license id command on the device or from the label on the unit. If
you received a paperpack transaction key, write the LID in the space provided on the entitlement
certificate.
NOTE
Do not discard the entitlement certificate or e-mail with the electronic key. Keep it in a safe place
in case it is needed for technical support or product replacement (RMAs).
