If you're using vQFX on any simulating tools, you might have noted that it
comes up with a pre-configuration, that may not be required to run or test
your labs. It gives a total messed up view when you check the configurations
on the switch. I'm running this lab on EVE-NG.
To check the configurations, use the below commands in operational mode or
configuration mode.
root@vqfx-re> show configuration | no-more
root@vqfx-re# show | no-more
As previously mentioned, we don't need all the configuration to run our
lab, but we need to note down the internal interface's IP address before
deleting the entire configurations, which is required for the communication
between the RE and PFE. The IP address is assigned to the
interface em1 unit 0.
root@vqfx-re> show interfaces em1.0 terse
Interface Admin
Link Proto Local
Remote
em1.0
up up inet
169.254.0.2/24
Now go to configuration mode and delete all the configurations.
root@vqfx-re> configure
root@vqfx-re# delete
This will delete the entire configuration
Delete everything under this level? [yes,no] (no) yes
You won't be able to commit at this point as the configuration is empty.
You will get an error if you do so.
root@vqfx-re# commit
error: cannot commit an empty configuration
root@vqfx-re#
set system root-authentication plain-text-password
New password:
Retype new password:
root@vqfx-re# commit
Now configure the internal interface with the IP 169.254.0.2/24 to
restore the communication between RE and PFE.
root@vqfx-re# set interfaces em1 unit 0 family inet address 169.254.0.2/24
root@vqfx-re# commit
Check the configuration, now you will see only the changes you have
made. It gives a fresh look and will make troubleshooting easy.
