Re: FEX Showing offline

Hi Rishad,

 

Is this a new FEX you are connecting? Have you configured the other side of parent vpc switch? If firmware miss-match is there it will go offline and come again with parent switch version. 

 

FEX version: Unknown [Switch version: 7.1(0)N1(1b)] 
FEX Interim version: Unknown 

If config is fine, please provide below output: 

 

# sh interface fex-fabric
#sh port-channel summary
# show logging last 50
show system internal fex internal errors
show system internal fex info satport all
show system internal fex info satellite all
show system internal fex log
show system internal fex internal event-history error

 

Please rate if you find it helpful. 

 

Regards,

MJ
