Hi all, I see several MX firewalls (in HA setup) having problems with their uplink ports: - We have MX85s which dropped their uplink connections. We first heard it could possibly be caused by a Energy Efficient Ethernet but neither devices we connected the MX to supported this. Now we got the advice to use Copper SFPs instead of the normal ethernet ports on the MX (this got me thinking that a static speed/duplex setting also might work, not that I favor such settings....). - A customer with 2 MX 450s (HA) sees a lot VRRP changes related to Uplinks falling away. They are using 10G DAC-cables connected to a MS250 which functions as a WAN-switch. - In the release notes I see that the MX100 also has an uplink issue. - Another customer with MX250s seems to have the same issues Most of the time when the spare is shut down, things stay stable. Most issues seem to arise after an upgrade to 16.x (in case of the 450s issues started when upgrading to the last 14.x version, 16.x seemed to stabilize but the problems returned). What's going on here and why are there so many different models affected suddenly? It's not my point to discuss every issue separately, I was just wondering why there is such a flood of issues with uplinks on (mostly) HA-pairs. With kind regards, Marcel Tempelman
