Installed and Uninstalled Ports

Installed and Uninstalled Ports
An installed port refers to a port for which all required hardware is present. A specified port number in a
VSAN can be implemented, and yet not installed, if any of the following conditions apply:
• The module is not present—For example, if module 1 is not physically present in slot 1 in a Cisco MDS
• The small form-factor pluggable (SFP) port is not present—For example, if a 16-port module is inserted
• For slot 1, ports 0 to 31, or 0 to 15 have been assigned. Only the physical port fc1/5 with port number 4
Another scenario is if VSANs 1 through 5 are FICON-enabled, and trunking-enabled interface fc1/1 has
VSANs 3 through 10, then port address 0 is uninstalled in VSAN 1 and 2.
• The port is part of a PortChannel—For example, if interface fc 1/1 is part of PortChanne1 5, port address

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
• Each PortChannel must be explicitly associated with a FICON port number.
• When the port number for a physical PortChannel becomes uninstalled, the relevant PortChannel
• Each FCIP tunnel must be explicitly associated with a FICON port number. If the port numbers are not

Assigning FICON Port Numbers to Slots

You can use the show ficon port-number assign and show ficon first-available port-number commands
to determine which port numbers to use.
Caution
When you assign, change, or release a port number, the port reloads.
To assign FICON port numbers to a slot, follow these steps:

is in VSAN 2. The rest of the physical ports are not in VSAN 2. The port numbers 0 to 249 are considered
implemented for any FICON-enabled VSAN. Therefore, VSAN 2 has port numbers 0 to 249 and one
physical port, fc1/4. The corresponding physical ports 0 to 3,and 5 to 249 are not in VSAN 2. When the
FICON VSAN port address is displayed, those port numbers with the physical ports not in VSAN 2 are
not installed (for example, ports 0 to 3, or 5 to 249).
