Manually Upgrade APICs via CLI (Step by Step) – Cisco ACI

Step-1: Download and copy the APIC image from a source to the APIC controller filesystem

apic-1# cd /home/admin
apic-1# scp <username>@<Host_IP_where_image_located>:/<absolute path to the image including image file name>  .

Example:

apic-1# scp root@192.168.20.55:/iso/aci-apic-dk9.6.0.4c.iso  .

Verification:

apic-1# cd /home/admin
apic-1# ls aci-apic-dk9.6.0.4c.iso


Step-2: Add image to APIC firmware repository

apic-1# pwd
/home/admin
apic-1# firmware repository add <image file>

Example:

apic-1# firmware repository add aci-apic-dk9.6.0.4c.iso

Verification:

apic-1# show firmware repository

 Name                                      Type        Version        Size(MB)   
 ----------------------------------------  ----------  -------------  ----------      
 aci-apic-dk9.6.0.4c.bin                   controller  6.0(4c)        6161.941   


Step-3: Configure the APIC for upgrade or downgrade

apic-1# configure
apic-1(config)# firmware
apic-1(config-firmware)# controller-group
apic-1(config-firmware-controller)# firmware-version <name of the image file>

Example:

apic-1# configure
apic-1(config)# firmware
apic-1(config-firmware)# controller-group
apic-1(config-firmware-controller)# firmware-version aci-apic-dk9.6.0.4c.bin


Step-4: Start the upgrade or downgrade of APICs

apic-1(config-firmware-controller)# exit
apic-1(config-firmware)# exit
apic-1(config)# exit
apic-1# firmware upgrade controller-group

The upgrade/downgrade of the APIC will occur one by one in background.


Step-5: Verify the Upgrade/downgrade status

apic-1# show firmware upgrade status 
 Pod         Node        Current-Firmware      Target-Firmware       Status                     Upgrade-Progress(%)   Download-Status            Download
-Progress(%) 
 ----------  ----------  --------------------  --------------------  -------------------------  --------------------  -------------------------  --------
------------ 
 1           1           apic-6.0(4c)          apic-6.0(4c)          success                    100                   -                          -       
             
 1           2           apic-6.0(4c)          apic-6.0(4c)          success                    100                   -                          -       
             
 1           3           apic-6.0(4c)          apic-6.0(4c)          success                    100                   -                          -
