Configure Fabric Parameters

Use the procedures in this section to configure the following Fibre Channel
operating parameters using the Configure Fabric Parameters dialog box. The
operating parameters are stored in NV-RAM on the switch.
You can configure the following fabric operating parameters as required by your
fabric:
Note:
value is not the same on all units, the fabric segments. Also, the value for R_A_TOV
must be greater than the value configured for E_D_TOV.
Note:
value is not the same, the fabric segments.

R_A_TOV
Resource allocation time-out value. This variable is used to time out
operations that depend on the maximum possible time that a frame can be
delayed in a fabric and still be delivered. Adjust the value for R_A_TOV in
tenths of a second (100 ms) increments over a range of 10 tenths (1 second) to
1200 tenths (120 seconds). The default value is 100 tenths (10 seconds).
Set the same value for R_A_TOV on all switches on a multi-switch fabric. If the
E_D_TOV
Error-detect time-out value: This defines the time that the switch waits for an
expected response before declaring an error condition. Configure this value in
tenths of a second (100 millisecond) increments in a range of 2 tenths of a
second to 600 tenths (60 seconds). The default value is 20 tenths (2 seconds).
Set the same value for E_D_TOV on all switches on a multi-switch fabric. If the
Switch Priority
Setting this value determines the principal switch for the multi-switch fabric.
Select either Principal (highest priority), Default, or Never Principal (lowest
priority) from the Switch Priority drop-down list.
