We are a small ISP and we provide FTTH for business and private households at our location.
We are using hEX S (FW 6.45.
with 1GB single fibre SFPs from FS.com (TX 1310 / RX 1490 at customer site) and Alcatel SAS-M on provider site.
Sometimes I cannot reach some routers.
When I look from internal, I see that the SFP is receiving laser Rx Power and seems so be up and running(R) on interface list.
But on Interface List Rx Pakets, I get no pakets (0 bps).
[*]Replacing SFP does not help
Turn off and on SFP Interface on customer side does not help
Turn off and on SFP Interface on provider side does not help
The only way to solve the issue is to reboot the customer router.
Does anyone have similar problems or an idea?
Thanks for your help.
PS: Of course, it would be possilbe to reboot the customer router by script if WAN ping is not ok, but this won't be my favorite solution.
