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):
•
•
•
Note The fabric stability TOV (F_S_TOV) constant cannot be configured.
This section includes the following topics:

Timer Configuration Across All VSANs

You can modify Fibre Channel protocol related timer values for the switch.
The D_S_TOV, E_D_TOV, and R_A_ TOV values cannot be globally changed unless all VSANs in the
Caution
switch are suspended.
Note If a VSAN is not specified when you change the timer value, the changed value is applied to all VSANs
in the switch.
To configure timers in Fabric Manager, expand Switches > FC Services and then select Timers &
Policies in the Physical Attributes pane. You see the timers for multiple switches in the Information
pane. Click the Change Timeouts button to configure the timeout values.
You see the dialog box as shown in

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.
