The default BB Credit is 16. The range of valid values is from 1 through 27. Resource allocation timeout value (in milliseconds). This variable works with the E_D_TOV to determine switch actions when presented with an error condition. The default is 10000. The possible range is (2*E_D_TOV) -120000. Values must be multiples of 1000. Error detect timeout value (in milliseconds). This timer is used to flag a potential error condition when an expected response is not received within the set time. The valid range is 1000 - (R_A_TOV/2) 40 Web Tools Administrator's Guide 53-1002756-01

The buffer-to-buffer credit is the number of buffers available to attached devices for frame
receipt. The default BB Credit is 16. The range of valid values is from 1 through 27.
R_A_TOV
Resource allocation timeout value (in milliseconds). This variable works with the E_D_TOV
to determine switch actions when presented with an error condition. The default is 10000.
The possible range is (2*E_D_TOV) –120000. Values must be multiples of 1000.
E_D_TOV
Error detect timeout value (in milliseconds). This timer is used to flag a potential error
condition when an expected response is not received within the set time. The valid range
is 1000 - (R_A_TOV/2)
