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.
