Qfx-3500

‎02-02-2015 10:17 AM

Hi all

I have a very annoying bug on qfx-3500 series:

I cannot get out virtual chassis mode :

I have upgraded an qfx-3500 and it turned to VC without reason.

The point is :

- It is impossible to display virtual chassis mode

- I cannot return back to standalone mode, even with a zeroize

How can I retrieve normal operation ?

Thanks for help, find below logs

From what to what version did you upgrade?

 

You can use this procedure to wipe everything out and install a fresh Junos:

If this worked for you please flag my post as an "Accepted Solution" so others can benefit. A kudo would be cool if you think I earned it.

Hi

 

I am not confident it will solve my problem : a fresh installation will turn the qfx-3500 in virtual-chassis mode

 

I am searching a way to go back to standalone.

 

Regards.

Hi,

    Even I am having the same error. I have a virtual chassis configured in my QFX3500. I did a zeroize but still when I login using a console port it tries to login to the master..login to master fails and it then logs in on its local cli. I want to operate this router as a standalone. I am not even able to access it using ssh (I think the VC configuration is interfering in the ssh process) Can you please tell me what you did to operate it as a standalone switch?

root@spine2-bhoomi# run show virtual-chassis status

Thank You

HI

 

Post doing a format install you may do a device mode change.

 

You could also try removing the vc files from the system

 

% cd /config/
% ls
db                      ssh_host_dsa_key        ssh_host_rsa_key
juniper.conf.1.gz       ssh_host_dsa_key.pub    ssh_host_rsa_key.pub
juniper.conf.2.gz       ssh_host_ecdsa_key      usage.db
juniper.conf.3.gz       ssh_host_ecdsa_key.pub  vchassis
juniper.conf.gz         ssh_host_key
juniper.conf.md5        ssh_host_key.pub
% cd vchassis/
% ls
vc.db                   vc.tlv.db.0             vclocal.conf.tlv
vc.param                vc.tlv.db.1             vclocal.conf.tlv.0
vc.tlv.db               vclocal.conf            vclocal.conf.tlv.1

% rm -rf *.*

 

request virtual-chassis reactivate OR

 

Reboot with above procedure and check.

 

Thanks

Hi,

 

I have the same problem on a QFX3500 stuck in _linecard_ mode. Right now, I can't find any solution in the previous messages, or even on Google.

I have two problems:

 

1) In /config, I cannot delete or zeroize the file "usage.db".  Is it a file related to virtual chassis?

 

2)

{linecard:0}

root> request virtual-chassis reactivate

error: abnormal communication termination with virtual-chassis-control daemon

 

How can I launch manualy this daemon?
