‎08-07-2016 09:32 PM

Hi 

 

I am facing one issue in EX 4200 stack of 3 switches. One is master other is backup and lastone is line card.

 

Presently Line card showing "not present"  when issue show virtual-chassis command.

 

Chassis was working since last 7 months without any issues. No modification and no cable changes are made.

 

Powe is also upin entire chassis.

 

 

Please let me know the possible cause of solution.

 

 

Thanks'

 

Amit

Crashed or corrupted software running on linecard, faulty VC cable, or faulty hardware.

HI Amit,

 

Please add the below outputs

 

show version 

show virtual-chassis

 

If the new member is member 2 please try to login to the member from master VC

 

reqeust session member 2

 

ELSE

Try pinging the member from shell

 

ping -Ji fpc2

 

If both works and members is still showing inactive possibly it has a different Junos compared to master and Backup.

 

How this can happen as this was working fine for last 7 months? 

 

May be it rebooted and booted up from alternate partition.

 

Thanks

Partha

Sounds like versions are different.

Another possibility is the switch booted to the alternate root and that was out of date in version and config from the main partition.  If this is the case a simple upgrade to the correct version of code should allow it to rejoin the VC.
