To view detailed FDMI information for a device, click the Devices tab, and click (i) in the Details column of the Devices data window. The Detailed Devices Display dialog box displays the specific information for that device. For more information, see "Devices data window" (page 39). Advanced switch properties (timeout values) The Advanced Switch Properties dialog box (Figure 53) enables you to set the timeout values for all ports on the switch, and is available only on the entry switch. The timeout values must be the same for all switches in the fabric. IMPORTANT: Timeout values should not be changed unless absolutely necessary. You must place the switch offline to change these values. To change timeout values: 1. Select the entry switch in the fabric tree. 2. Select Switch > Switch Properties to open the Switch Properties dialog box (Figure 52). 3. Select Offline in the Administrative State field, and click OK. When the application confirms that the change has been applied, proceed. 4. Select Switch > Advanced Switch Properties to open the Advanced Switch Properties dialog box (Figure 53). Figure 53 Advanced Switch Properties dialog box 5. Make changes to the R_A_TOV and E_D_TOV switch timeout values: • R_A_TOV (Resource Allocation Timeout)-The maximum time a frame could be delayed and still be delivered. The default is 10000 milliseconds. • E_D_TOV (Error Detect Timeout)-The maximum round trip time that an operation between two N_Ports could require. The default is 2000 milliseconds. 6. Click OK to put the new values into effect. 7. Select Switch > Switch Properties to open the Switch Properties dialog box. 8. Select Online in the Administrative State drop-down list, and click OK to place the switch back online. 9. Repeat this procedure on every switch in the fabric to ensure that all timeout values are the same. 96 Managing Switches

Managing Switches
To view detailed FDMI information for a device, click the
Devices
tab, and click
(i)
in the Details column of
the Devices data window. The Detailed Devices Display dialog box displays the specific information for
that device. For more information, see ”
Devices data window
” (page 39).
Advanced switch properties (timeout values)
The Advanced Switch Properties dialog box (
Figure 53
) enables you to set the timeout values for all ports
on the switch, and is available only on the entry switch. The timeout values must be the same for all
switches in the fabric.
IMPORTANT:
Timeout values should not be changed unless absolutely necessary. You must place the
switch offline to change these values.
To change timeout values:
1.
Select the entry switch in the fabric tree.
2.
Select
Switch > Switch Properties
to open the Switch Properties dialog box (
Figure 52
).
3.
Select
Offline
in the Administrative State field, and click
OK
. When the application confirms that the
change has been applied, proceed.
4.
Select
Switch > Advanced Switch Properties
to open the Advanced Switch Properties dialog box
(
Figure 53
).

R_A_TOV (Resource Allocation Timeout)—The maximum time a frame could be delayed and still be
delivered. The default is 10000 milliseconds.
E_D_TOV (Error Detect Timeout)—The maximum round trip time that an operation between two
N_Ports could require. The default is 2000 milliseconds.
6.
Click
