Introduction
25Fabric Interoperability: Merging Fabrics Based on C-Series and M-Series Fibre Channel Switches Application Notes
Troubleshooting
1. After merging the fabrics, if you see segmentation errors on any of the switches, verify
that interoperability mode is enabled on all switches in the fabric
2. Ensure all the time out values are set properly, specially E_D_TOV (2 secs) and
R_A_TOV (10 secs)
3. If you see an ISL on the M-Series product that segments due to a Build Fabric Protocol
Error, you can recover by blocking, then unblocking the port. You may need to do this
several times.
4. If you have zone merging problems, check the following:
■ Remember the Active Zone set in the M-Series and the Active Zone set in the C-series
must be unique. You cannot have the same zone name with different WWN members.
■ Only WWN zoning is permitted for heterogeneous fabrics. Domain, Port, or Area
zoning are not supported.
■ Make sure the zones are compatible between the M-Series and C-series. See step-M5
and step C5 described earlier in this document
