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.
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.
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.
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.
Maximum hops (MAX_HOPS) is an integer that denotes the upper limit on the
number of hops a frame might have to traverse to reach any destination port from
any source port across the fabric.
