Chapter 23 Configuring FICON
MDS FICON Prerequisites
FC ID Allocation
FICON requires a predictable and static FC ID allocation scheme. When FICON is enabled, the FC ID
allocated to a device is based on the port address of the port to which it is attached. The port address
forms the middle byte of the fabric address. Additionally, the last byte of the fabric address should be
the same for all devices in the fabric. By default, the last byte value is 0 and can be configured.
Note You cannot configure persistent FC IDs in FICON-enabled VSANs.
Cisco MDS switches have a dynamic FC ID allocation scheme. When FICON is enabled or disabled on
a VSAN, all the ports are flapped to switch from the dynamic to static FC IDs and vice versa.
Figure 23-5 Static FC ID Allocation for FICON
FICON Cascading
The SAN-OS software allows multiple switches in a FICON network. To configure multiple switches,
you must enabled and configure fabric binding in that switch.
MDS FICON Prerequisites
To ensure that a FICON VSAN is operationally up, be sure to verify the following requirements:
•
Set the default zone to permit, if you are not using the zoning feature.
• Enable in-order delivery on the VSAN.
•
Enable (and if required, configure) fabric binding on the VSAN.
• Verify that conflicting persistent FC IDs do not exist in the switch.
•
Verify that the configured domain ID and requested domain ID match.
• Add the CUP (area FE) to the zone, if you are using zoning.
If any of these requirements are not met, the FICON feature cannot be enabled.
Static Domain Port Address Last Byte
5 0x44 0
Static FC ID allocation for interface fc3/5 includes the
static domain ID (5), the port address (0x44), and the last byte value (0).
