Problem with sh int status on a Nexus 5596

Aret Avedis SET

Level 1

Hello,

I have maybe a bug on my Nexus 5596 switch ; when i issue the command show interface status the outpout of the "port" is missing :

# sh int statu 

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

Port          Name               Status    Vlan      Duplex  Speed   Type

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

connected trunk     full    10G     1/10g

But we see the fex interfaces :Eth101/1/1, Eth103/1/1, etc...

Eth101/1/1    *** ****************connected       full    1000    --        

Eth101/1/2    *** *************** connected      full    1000    --        

Eth101/1/3    **

I have other 5596 with the same version 5.0(3)N2(2a) and there is no problem ; i do nothing for this, it was working before but now it's not.

Did you seen this problem before ?

Thanks for your feedback.

on this switch, do you remember copying any files created via windows/dos to the running config lately? can you paste a sample  'show interface ethernet x/y' for the port which is missing the port information in 'show int status'

Thanks, Vinayak

Hi,

Yes when i implement a config, i always work with notepad or word and copy/paste the configuration on the Nexus.

Here is the outpout that you asked :

N5K# sh int eth1/19

Ethernet1/19 is down (SFP validation failed)

And an outpout for an interface that is working :

N5K# sh int eth1/7

Ethernet1/7 is up

Thanks for your help

Thanks. There could be an issue with line characters after copying over the config from your notepad in windows. You can refer to the following command

nexus# d?

  debug         Debugging functions

  debug-filter  Enable filtering for debugging functions

  delete        Delete a file or directory

  diff-clean    Remove temp files created by '| diff' filters

  dir           List files in a directory

  dos2nxos      DOS to NXOS text file format converter <<<<

nexus# dos2nxos ?

  bootflash:  Filename to be displayed

  debug:      Filename to be displayed

  modflash:   Filename to be displayed

  usb1:       Filename to be displayed

  volatile:   Filename to be displayed

since you copy the configs frequently, you can use the dos2nxos command to convert the file to nxos first and then use the file for configuration. Right now, try to modify the config manually on the switch interfaces and see if that helps. You either readd 'description' command under the interface and check if the port starts showing up in 'show int status' or modify or repaste the entire interface config and check if that works.

Thanks, Vinayak

Thanks for the support ! after readding the description on the interfaces, the sh int status is now ok !

Thanks again !
