  • 1.  Link flapping every five and half hours

    Posted 01-28-2014 23:08

    Hi.

    We have a some strange problem.
    Juniper MX connected to Cisco Nexus 5548 via aggregate ethernet.
    Between Juniper and Cisco two 10G optical links.
    In October we began to receive messages about link down and link up.
    This happens every five and half hours (+/- 1 min) on both links. On cisco we have same messages, that means link realy down.
    We tried to replace sfp modules in cisco, but nothing been changed.
    Now we wait new XFP modules for replacement in Juniper.
    May be problem in juniper? I dont see any specific messages in logs about this.

    Hello,

     

    This stands out

     

    Physical interface: xe-0/0/0
    Laser bias current                        :  3.881 mA
    Laser output power                        :  0.2670 mW / -5.73 dBm
    Module temperature                        :  -85 degrees C / -120 degrees F

     

    Please read https://puck.nether.net/pipermail/juniper-nsp/2013-January/025397.html

    And I suggest You upgrade JUNOS - You are running EOL software so no more bug fixes on 11.2

    Hi!

    It seems to be true.

    I added in monitoring temperature XFP and saw the same picture.

    Thanks!
