If Eth0 is not being detected, please check /etc/network/interfaces and make sure the configuration has a format as below

 

 

For example, please check if there are any unwanted characters that might block the file from being read – for instance, in the below scenario there is an unwanted “ i “ character that got inserted by error.

 

 

 

If you observe such a condition, please remove the unwanted characters, and save the file – post which you would need execute the below

 

sudo ifdown eth0

sudo ifup eth0

 

Check the output of “ifconfig” to confirm if eth0 is being detected

 

Now, for eth0 to be re-read by VOS, you will need to perform a “vsh restart”  (this will restart the services so you would need to perform this in a maintenance window)

 

 

Note: That eth0 is the management port and though it’s read by VOS the interface still belongs to the kernel, this is accomplished by the below setting in vsboot.conf

 

 

 

For any other interface/port that’s not being detected by VOS, please check the below

 

  1. Check if it’s mac is listed in the output below

 

 

  1. Check if it’s listed in the lspci output

 

 

 

 

  1. Check for any errors in dmesg log for this port

 

 

 

  1. Check if the mac address is listed in the below output (this the mapping of mac to port for the whitebox)

 

 

  1. You can try a “power cycle” to see if the condition is restored

 

If not please collect the below output and open a TAC case

 

show interfaces brief

show interfaces port statistics brief

show interfaces detail vni-0/x                          (x being the number of the problematic port)

vsh connect infmgr    <<< from shell

show interfaces brief

exit

vsh connect vsmd

show vsm interfaces detail hw summary

show vsm interfaces detail hw device-info

show vsm statistics port

show vsm statistics port mac

show vsm statistics port mac dpdk
