A number of parameters control the overall behavior and operation of the fabric. Some
of these values, such as the domain, are normally assigned automatically by the fabric
and may be different from one switch to another in the fabric. However, other param-
eters, such as the buffer-to-buffer credit or the time out values, may be changed to
suit particular application programs or operating environments, but must be in agree-
ment among all switches to allow formation of the fabric.
Table 4-4 defines the settings affecting the fabric.
