The following parameters can be modified with the configure command:
Switch Fabric Settings
Fabric settings control the overall behavior and operation of the fabric. Some of these settings,
such as the domain, are assigned automatically and may differ from one switch to another in a
given fabric. Other parameters, such as buffer-to-buffer credit or timeout values, can be modified to
suit specific applications or operating environments but must be in agreement among all switches
to allow formation of the fabric.
The following Switch Fabric Settings can be modified:
Fabric setting fields are defined as follows:
Domain The domain number uniquely identifies a switch in a fabric. This value is
automatically assigned by the fabric. The range of valid values varies
depending on the switch model and other system parameter settings.
R_A_TOV The resource allocation time out value (R_A_TOV) is displayed in milliseconds.
This variable works with the variable E_D_TOV to determine switch actions
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 time out, the
internal time-out clock resets and waits for the next error condition.
E_D_TOV Error detect time out value (E_D_TOV) is displayed in milliseconds. This timer
is used to flag a potential error condition when an expected response is not
received (an acknowledgment or reply in response to packet receipt, for
example) within the set time limit. If the time for an expected response
exceeds the set value, then an error condition occurs.
