Verify Software and Hardware Version Information

Cumulus Linux users familiar with Cisco IOS might look for the same level of information from commands they learned and used over time. One of the most common commands used in Cisco IOS is show version, which displays the currently loaded software along with hardware and device information. You can find this level of information in Cumulus Linux using the following commands:

• cat /etc/lsb-release
• cl-img-select
• decode-syseeprom

Use cat /etc/lsb-release to Verify the Running System Image

The following command displays the version of Cumulus Linux running in the current slot, and is updated to reflect version changes with apt-get:

cumulus@switch:~$ at /etc/lsb-release
DISTRIB_ID="Cumulus Linux"
DISTRIB_RELEASE=4.2.0
DISTRIB_DESCRIPTION="Cumulus Linux 4.2.0"

Use decode-syseeprom to Verify Hardware Model, Version and Other Vendor-specific Details

Similar to how Cisco offers the show idprom command for IOS and show sprom for NX-OS, NVIDIA created the decode-syseeprom command to provide a universal EEPROM format that delivers a consistent way to display hardware platform-specific information. All vendors approved on the Cumulus Linux hardware compatibility list adhere to this EEPROM format for Cumulus Linux certification.

For example:

cumulus@switch:~$ sudo decode-syseeprom

Determine the Version of the Installed ONIE Software

Determining the ONIE version depends on the hardware architecture. The following command determines the hardware platform:

cumulus@switch$ uname -m

x86

Reading the ONIE version on an x86 switch requires temporarily mounting the ONIE partition as follows.

1. Temporarily mount the ONIE partition read-only to read the ONIE version:

   cumulus@switch$ sudo mkdir /mnt/onie
   cumulus@switch$ sudo mount -o ro -L ONIE-BOOT /mnt/onie
   

2. Read the ONIE version:

   cumulus@sw5$ grep ^onie_version /mnt/onie/grub/grub.cfg
   onie_version=2014.08.0.0.3
   

3. Unmount the ONIE partition:

   cumulus@switch$ sudo umount /mnt/onie
   

PowerPC and ARM

The fw_printenv command is a U-Boot tool inherited from the standard Debian distribution. You can use it to query the onie_version, the version of ONIE installed with U-Boot.

For example:

cumulus@switch:~$ fw_printenv onie_version  
onie_version="1.3.0"
