I’m sure by now no one is surprised to see this post and issue. Its been an issue in the PtP TDD force 300 links for a long time now. However I just wanted to reach out to the group and see if anyone has come up with a solution.
We have had three links that all experienced the same issue where the SM side of the PtP link stops passing traffic on its lan port. A reboot of the unit restores connectivity. Sometime it lasts for a few hours sometimes for a week or more. One of these links we fixed by replacing the SM side hardware. The other link we replaced with force 200 units ( not ideal but works for now). The final link is still in use and as of a few hours ago just needed another reboot.
our most recent tries to stabilize this link has been to upgrade to firmware 3.5.5 and also 3.5 ( currently on 3.5) . we have also set the Ethernet on both ends to 100mbps instead of gb.
At this point I am about our of idea’s its frustrating when some links are rock solid and then others just go flaky like this.
Any feedback is appreciated.
