Normally, this value is automatically assigned by the fabric. The range of allowed values varies depending on the switch model and other system settings (see "VC Encoded Address Mode" on page 166). BB Credit The buffer-to-buffer (BB) credit represents the number of buffers available to attached devices for frame receipt. R_A_TOV The resource allocation timeout value (R_A_TOV) is displayed in milliseconds. This variable works with the E_D_TOV variable to determine the 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 before the timeout, the internal timeout clock resets and waits for the next error condition. E_D_TOV The error detect timeout 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, an error condition is met. Fabric OS 3.x Document Addendum 165
