Hello,
I have a bit of a problem here. I have 2 Passport 8606 core switches that are interconnected with an IST MLT links. From these switches there are several SMLT links running to Passport 1624 Distribution switches. All those links are fiberlinks of 1 Gb. To one location this SMLT is build with a Singlemode fiber and a Laserlink through the air (Laserbit Gigabit Pinto).
Sometimes this Laserbit connection has some trouble due to fog etc and this connection starts to break and come up again very fast after on another. The result is that sometimes the Passport 8606 thinks it sees a loop on this port and drops this connection. This would not be a problem except that the moment this Laserbit connection drops the whole SMLT sometimes stops transporting packets and the site that should be connected is gone completly. Most of the times when this happens I have to disconnect the laserbit from the network and the SMLT comes back online.
On the Passport 1624 the SMLT is connected to port 23 and 24 of the switch.
Are there some known problems with SMLT links in the used firmware of the Passport 8606 switch, if so, are there firmware revisions that fix this problem?
Are there some other issues that I am not aware of that could result in this configuration being instable?
Thanks a lot, Jan Hugo Prins
