Advanced switch properties
The Advanced Switch Properties dialog box (Figure 28) enables you to set the timeout values. The dialog
box is available for only the entry switch. The switch is automatically taken offline temporarily while the
timeout values are being set and will be restored to its original state after the changes are complete. To
open the Advanced Switch Properties dialog box, open the Switch menu and select Advanced Switch
Properties. After making changes, click OK to put the new values into effect.

Timeout values
The switch timeout values determine the timeout values for all ports on the switch. The timeout values must
be the same for all switches in the fabric.
• 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.
IMPORTANT: Mismatched timeout values disrupt the fabric. These should not be changed unless
absolutely necessary. The switch is temporarily placed offline to change these values.
Managing system services
The System Services dialog box (Figure 29) provides a central location for you to enable or disable any of
the external user services such as Simple Network Management Protocol (SNMP), embedded web applet,
command line interface, Network Time Protocol (NTP), Common Information Model (CIM), and Call
Home. To display the System Services dialog box, select Switch > Services.
