FICON commands

NOTE

The Fabric OS CLI supports only a subset of the Brocade management features for FICON fabrics.

The full set of FICON CUP administrative procedures is available using the Brocade Data Center

Fabric Manager and Web Tools software features. You can also use an SNMP agent and the FICON

Management Information Base (MIB).

Table 1

summarizes the Fabric OS CLI commands that can be used for managing FICON fabrics.

For detailed information on these commands, see the

Fabric OS Command Reference
