The messages in this section are displayed if an exception case is encountered during firmware downgrade. The following example shows feature-related messages that you may see if you were downgrading from v6.4.0 to v6.3.0: Downgrade is not allowed because there are ports configured on FX8-24 as VEX. Please use "portcfgvexport CLI" to remove the VEX configuration. Downgrade is not allowed because a range of ports not supported by the target firmware are assigned to Logical Switches instead of Default Switch. Please use "lscfg --restore_to_default FID" to move all vacant ports to the default. Downgrade is not allowed because there are ports configued in CSCTL mode. Please use "portcfgqos CLI" to disable the CSCTL mode Downgrade is not allowed because dynamic area mode is enabled on default switch, Please use "configure" CLI to turn this mode off Downgrade is not allowed because zoning configuration has overlapping (enhanced) TI zones in one or more contexts. Please use "zone --delete zone_name" command to delete overlapping TI Zones before proceeding. Downgrade is not allowed because either 1) One of the peer switch is configured to use third party issued certificates, or 2) Certificate files exist. Please remove or set the configurationto Brocade and delete certificate files using "seccertutil delete -fcapall" before downgrading. DSCP Marking for 7800/FC8-24 required firmware version v6.4.0 or higher. Please remove the DSCP marking using the "portCfg fcipcircuit modify" command before downgrading. IPv6 for 7800/FX8-24 requires firmware version v6.4.0 or higher. Please remove any FCIP circuits using IPv6 addresses using the "portCfg fcipcircuit delete" command before downgrading firmware. Advanced compression modes (moderate, aggressive) for FCIP tunnels on FX8-24 requires firmware version v6.4.0 or higher. Please switch to standard compression using the "portCfg fciptunnel modify" command before downgrading. Fabric OS Troubleshooting and Diagnostics Guide 59 53-1001769-01
