MX80 TFEB reboots upon fibre being plugged in

Hi,

 

We have an MX80 where a vendor plugged in their end of the fibre today which caused the whole TFEB 0 to reboot. Service couldnt be restored and the system not accessable until the fibre was physically inplugged.

 

The closest I could find similar to this fault was from back in 2006 - http://puck.nether.net/pipermail/juniper-nsp/2006-April/006334.html

Re: MX80 TFEB reboots upon fibre being plugged in

The output from "show chassis hardware", there are some un-supported SFPs which were plugged into MX80, maybe this is the reason TFEB was reboot. You should use compatible SFPs with this device and the best would be Juniper SFPs, then try test double-check wherther or not the problem happen again.

Re: MX80 TFEB reboots upon fibre being plugged in

Since there is a crash file , open a JTAC ticket.

Seems it crashed as the traffic hit the port..
