106 Administering FICON fabrics

Switch binding is a security method for restricting devices that connect to a particular switch. If the

device is another switch, security handled by the SCC policy. If the device is a host or storage device,

the Device Connection Control (DCC) policy binds those devices to a particular switch. Policies range

from completely restrictive to reasonably flexible, based upon customer needs.

Port binding is a security method for restricting host or storage devices that connect to particular switch

ports. The DCC policy also binds device ports to switch ports. Policies range from completely

restrictive to reasonably flexible, based upon customer needs.

There are two types of FICON configurations:

A single-switch configuration (called switched point-to-point) requires that the channel be configured to

use single-byte addressing. If the channel is set up for two-byte addressing, the cascaded configuration

setup applies. This type of configuration is described in ”

Configuring a single switch

” on page 108.

A cascaded configuration (known as a high-integrity fabric) requires a list of authorized switches. This

authorization feature (called fabric binding) is available through Secure Fabric OS. The fabric binding

policy allows a predefined list of switches (domains) to exist in the fabric and prevents other switches

from joining the fabric. This type of configuration is described in ”

Configuring a high-integrity fabric

on page 109.

CUP protocol is used by IBM mainframe management programs to provide in-band management for

FICON switches. When it is enabled, you can set up directors in a FICON environment to be managed

through IBM mainframe management programs. CUP is an optionally licensed feature available with

Fabric OS 4.4.0 or later.

Table 18

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

detailed information on these commands, see the HP StorageWorks Fabric OS 5.x command reference

guide.
