> # FICON Port Numbering Guidelines

> The following guidelines apply to FICON port numbers:

> - Supervisor modules do not have port number assignments.
> - Port numbers do not change based on TE ports. Since TE ports appear in multiple VSANs, chassis-wide unique port numbers should be reserved for TE ports.
> - Each PortChannel must be explicitly associated with a FICON port number.
> - When the port number for a physical PortChannel becomes uninstalled, the relevant PortChannel configuration is applied to the physical 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, then the associated ports will not come up.

> See the "About Port Numbers for FCIP and PortChannel" topic.
