Fibre Channel Time Out Values
To configure timers in Fabric Manager, choose Switches > FC Services > Timers & Policies on the
Physical Attributes tree. You see the timers for multiple switches in the Information pane. Click the
Change Timeouts button to configure the timeout values.
To configure timers in Device Manager, choose FC > Advanced > Timers/Policies. You see timers for
a single switch in the dialog box.
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.
