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. MAX_HOPS 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.
