Configuring the Switch

Figure 3-3 Configure Fabric Parameters Dialog Box

Ordinarily, you do not need to change values in this dialog box from their

defaults. The only exception is the Preferred Domain ID. Change this value if

the switch will participate in a multiswitch fabric.

4. Use information under Switch Parameters to change settings as

required for parameters in this dialog box.

5. After you change settings, click the Activate button.

Fabric Parameters

Configure the following parameters as required by your fabric.

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 multiswitch fabric. If

the 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.

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).
