FICON Port Numbering

With reference to the FICON feature, ports in Cisco MDS switches are identified by a statically defined
8-bit value known as the port number. A maximum of 255 port numbers are available. You can use the
following port numbering schemes:

The following guidelines apply to FICON port numbers:

Note When you assign, change, or release a port number, the port goes offline and then back online as a result
of the change.

Default FICON Port Numbering Scheme

Default FICON port numbers are assigned by the Cisco MDS SAN-OS software based on the module
and the slot in the chassis. The first port in a switch always starts with a zero (0).

Default port numbers based on the chassis type
Reserved port numbers
Supervisor modules do not have port number assignments.
Chassis-wide unique port numbers should be reserved for trunking expansion (TE) ports since TE
ports appear in multiple VSANs.
Each PortChannel must be explicitly associated with a FICON port number.
For individual ports in a PortChannel, the configuration of the port corresponding to the
PortChannel is applied and not that of the individual port.
Each FCIP tunnel must be explicitly associated with a FICON port number. If the port numbers are
not assigned for PortChannels or for FCIP tunnels, the associated ports will not come online.
