> # Fibre Channel Time-Out Values

> You can modify Fibre Channel protocol related timer values for the switch by configuring the following time-out values (TOVs):

> - Distributed services TOV (D_S_TOV)—The valid range is from 5,000 to 10,000 milliseconds. The default is 5,000 milliseconds.
> - Error detect TOV (E_D_TOV)—The valid range is from 1,000 to 10,000 milliseconds. The default is 2,000 milliseconds. This value is matched with the other end during port initialization.
> - Resource allocation TOV (R_A_TOV)—The valid range is from 5,000 to 10,000 milliseconds. The default is 10,000 milliseconds. This value is matched with the other end during port initialization.

> Note The fabric stability TOV (F_S_TOV) constant cannot be configured.
