Insistent Domain ID Mode boolean 0 0 or 1
Domain The domain number uniquely identifies the 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.
WAN_TOV Wide area network time out value (WAN_TOV) displays in
milliseconds. This timer is the maximum frame time out value for
a WAN, if any, interconnecting the Fibre Channel islands.
