Hello, I hope someone can help with this. we have 2 buidings that were recently connected by lasers. The lasers are connected to thier respective switches in each bulding. Building 1's laser is connected to a 6509 switch running catos software Version NmpSW: 6.4(21) Through gbics. Building 2's Laser is connected to a 4505 switch running software IOS Version 12.2(25) gbics. Since these buildings were connected we have been experiencing intermittent drops in connection 2-3 times an hour. Both switch ports are enabled Full-duplex. During a show tech these errors are reported:
The 6509 switch shows FCS-Err 81
I have been told that this is a fiber problem. Could it also be that the 6509 catos needs to be updated?
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
