Figure 22 Configure Fabric Parameters dialog box (Edge Switch 2/32)
NOTE: Ordinarily, you do not need to change the values in this dialog box from their defaults.
Change the values only if the switch will participate in a multiswitch fabric.
3. Use the information under ” Fabric Parameters ” on page 82 to change settings as required for
parameters in this dialog box.
4. After you change settings, click Activate.
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).
NOTE: 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 variable 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 ms)
increments in a range of 2 tenths of a second to 600 tenths (60 seconds). The default value is 20
tenths (2 seconds).
NOTE: Set the same value for E_D_TOV on all switches on a multiswitch fabric. If the value is not
the same on all units, the fabric segments.
