Finding Feature Information
Your software release might not support all the features documented in this module. For the latest caveats and feature information, see the Bug Search Tool at https://tools.cisco.com/bugsearch/ and the release notes for your software release.
Guidelines and Recommendations :
-
FEC on Cisco MDS 9000 Series switches should be disabled on 16 Gbps links.
-
Ensure that enough buffer credits are configured on MDS ports to cover the distance for the specific frame size.
-
Use logical link bundling via port channels across DWDM links even in case of different path lengths. The superior technology of port channels to any other logical bundling solution in the industry makes this possible and provides the benefit of higher reliability without impacting FSPF routing decisions.
-
Check with your DWDM vendor for specific configurations and setting, specifically for NOS/LOS propagation.
