Configuring fabric parameters
It is important to have consistent fabric configuration settings on switches within the same fabric, because
inconsistent parameters can cause fabric segmentation.
The Configure Fabric tab on the Administration page (see Figure 6 on page 24) allows you to view and
configure the following fabric parameters:
CAUTION: Be careful if you change the fabric parameter default values. The fabric might not work
correctly if the default values are changed.
• Domain ID: The domain number uniquely identifies the switch in a fabric. This value is automatically
assigned by the fabric if you do not configure it.
• BB credit: The buffer-to-buffer credit represents the number of buffers available to attached devices for
frame receipt. The range of allowed values is 1 through 32.
• R_A_TOV: The resource allocation timeout value in milliseconds. This variable works with the variable
E_D_TOV to determine the actions of the switch when presented with an error condition.
Allocated circuit resources with detected errors are not released until the time value has expired. If the
condition is resolved prior to the timeout, the internal timeout clock resets and waits for the next error
condition.
