The following items must be addressed before downloading the specified

firmware:

Downgrade is not allowed because there are more than 2 FX8-24 blades plugged

in to the chassis. The limit after downgrade is 2. Please plug out the extra

blades and rerun the command

Firmwaredownload command failed.

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 v7.0.0 to v6.4.x:

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 v7.0.0 or higher.

Please remove the DSCP marking using the "portCfg fcipcircuit<ve-port> modify"

command before downgrading.

IPv6 for 7800/FX8-24 requires firmware version v7.0.0 or higher. Please remove

any FCIP circuits using IPv6 addresses using the "portCfg fcipcircuit

<ve-port> delete" command before downgrading firmware.

Advanced compression modes (moderate, aggressive) for FCIP tunnels on FX8-24

requires firmware version v7.0.0 or higher. Please switch to standard

compression using the "portCfg fciptunnel <ve-port> modify" command before

downgrading.
