Modifying FICON emulation
FICON emulation may be enabled on a per FCIP tunnel basis. For the Brocade 7500 switch and
FR4-18i blade you can use the portCfg ficon modify command to make modifications to the
feature. For the Brocade 7800 switch and FX8-24 blade, use the portCfg fciptunnel command to
make modifications to the emulation feature.
For details on command usage, refer to the Fabric OS Command Reference.
CAUTION
You will need to bring the FCIP tunnel down in order to make changes. This process is disruptive
to all traffic on the tunnel.
1. Connect to the switches at both ends of the FCIP tunnel and log in using an account assigned
to the admin role.
2. Disable the FCIP tunnel at both ends where the FICON emulation feature is enabled.
