No, the internal switch version cannot be downgraded automatically. It will need to be set it manually.

Additional Information

Example:

  1. The current switch version is 5.7

fas2650-2n-1::*> system service-processor show
                               IP           Firmware
Node          Type Status      Configured   Version   IP Address
------------- ---- ----------- ------------ --------- -------------------------
fas2650-1a SP  online      true         5.7       XX.XXX.XXX.XXX
fas2650-1b SP  online      true         5.7       XX.XXX.XXX.XXX
2 entries were displayed.

internal switch version:
SP fas2650-1a*> sp switch-version
Version17 SB_XXII ETHSW RZM

  1. Downgrade SP Firmware from 5.7 to 5.6P1

fas2650-2n-1::*> system node image get -package http://XX.XXX.XXX.XXX/SP_FW.5.6P1.zip -node local

Software get http://.../SP_FW.5.6P1.zip started on node fas2650-1a
Downloading package. This may take up to 10 minutes.

fas2650-2n-1::*> system service-processor image update -node local -package SP_FW.5.6P1.zip
