Common Troubleshooting Commands in the CLI Use the following CLI commands to troubleshoot FICON issues: • show ficon • show ficon vsan vsan-id file ficon-file-name • show ficon vsan vsan-id portaddress • show ficon vsan vsan-id director-history • show fabric-binding status • show fabric-binding database • show fabric-binding violations • show in-order-guarantee Port Swapping The FICON port swapping feature is only provided for maintenance purposes. Follow these guidelines when using the FICON port swapping feature: • Port swapping is not supported for logical ports (PortChannels, FCIP links). • Port swapping is not supported between physical ports that are part of a PortChannel. • If the two ports involved in a port swap have incompatible configuration options, the port swap is rejected with an appropriate reason code. For example, if a port with BB_credits as 25 is being swapped with an OSM port for which a maximum of 12 BB_credits is allowed (not a configurable parameter), the port swapping operation is rejected. 16-8 Cisco MDS 9000 Family Troubleshooting Guide, Release 3.x OL-9285-05
