Setting up the APIC

[Jong wook kim]

Hi all

In the following process, if i lost the APIC  password ,  
i would like to know how to re-set the APIC.

--------------------------------------------------------------------------------------------------------------------------------------

The following is a sample of the initial setup dialog as displayed on the console:
Cluster configuration ...
Enter the fabric name [ACI Fabric1 #1]:
Enter the number of controllers in the fabric (1-16) [3]:
Enter the controller ID (1-3) [2]:
Enter the controller name [apic2]:
Enter address pool for TEP addresses [10.0.0.0/16]:
Enter the VLAN ID for infra network (1-4094)[4093]: <<< This is for the physical APIC
Enter the VLAN ID for infra network (1-4094) [4]: <<< This is for the Simulator
Enter address pool for BD multicast addresses (GIPO) [225.0.0.0/15]:
Out-of-band management configuration ...
Enter the IP address for out-of-band management: 192.168.10.2/24
Enter the IP address of the default gateway [None]: 192.168.10.254
Enter the interface speed/duplex mode [auto]:
Administrator user configuration...
Enable strong passwords? [Y]
Enter the password for admin:

Thank you very much.

Hi Jong-wook,

May I kindly ask you to open a Service Request so that we can help you out to change the password on the APIC?

Thanks and kind regards

Jong-wook,

You have some options:

A. Password Recovery

Reseting APIC 'admin' password 
 
1- Connect USB to the APIC. The USB is to contains single dummy file named 'aci-admin-passwd-reset'
 
2- Reboot the APIC

3- Interrupt the reboot when the prompt is shown "Press any key to enter the menu"

4- The next screen will show version of Linux installed on the APIC

5- Select the correct version 

6- Type 'e' to edit this command

7- Add "aci-admin-passwd-reset' to the end of the command and press enter

8- Press 'b' to boot.

9- the APIC will boot to a prompt and ask for the new 'admin' password

B. You can download the APIC filename.iso from www.cisco.com

http://software.cisco.com/download/release.html?mdfid=285968390&softwareid=286278832&release=1.0(1k)&relind=AVAILABLE&rellifecycle=&reltype=latest

* Load the image filename using CIMC\KVM and attaching\mounting .iso

* After the APIC firmware is loaded and reboots, it should boot up fresh and run thru the setup script again.

Note: this option can take a good amount of time to complete. 

C. As Ozden mentioned, open a Service Request with the Cisco TAC.

I hope this works!

Hi

Thank you for  reply! 

 I solved the problem.   As follows:

---------------------------------------------------------------------------------------------------------------------------------------------------

If the admin user will not authenticate, try to log in through rescue-user.

rescue-user is sort of a emergency user that will log in even if the APICs are not in a cluster.

you can run admin level commands such as "eraseconfig setup"

* SSH to your APIC(s) as "admin" user

* Use the "eraseconfig setup"

ie.

apic1:~> e
eraseconfig Erase configuration, restore to factory settings

apic1:~> eraseconfig
<CR> Carriage Return
setup Erases the setup data

----------------------------------------------------------------------------------------------------

Have a nice day!!!
