Description

This KB article describes how to determine the current BIOS version for the NFX device.

Symptoms

I'm planning to upgrade, but need to run a minimum BIOS version. How do I determine the current BIOS version?

Solution

In some situations, a minimum BIOS version will be required in order to perform some software upgrades.  To determine the current BIOS version, you will need to access vJUNOS0.  Once there, you can apply the command "show chassis firmware"

Example

{master:0}
jdm-sysuser> show chassis firmware
Part                     Type       Version
FPC 0                    U-Boot      ***                                       
                         loader           FreeBSD/i386 bootstrap loader 1.2    
                         BIOS       CBDE_SFP_00.21_01.01                        

{master:0}
jdm-sysuser>


In this example, we can see that this NFX device is running BIOS version 21_01.01.
