Timeout values
The switch timeout values determine the timeout values for all ports on the switch. Table 12 describes the
switch timeout parameters. The timeout values must be the same for all switches in the fabric.
NOTE: Mismatched timeout values will disrupt the fabric. These should not be changed unless absolutely
necessary. Therefore, the switch must be offline to change these values. Use the Switch Properties dialog to
take the switch offline.
Interop mode
Interop mode permits interoperability with other switches in the following environments:
•
Standard: Permits interoperability with
FC-SW-2 compliant switches and McDATA switches in Open
Fabric Mode. Valid domain IDs are 97–127.
• McDATA Fabric Mode: Permits interoperability with other McDATA switches in McDATA Fabric Mode.
Valid domain IDs are 1–31.
Enabling the 239 Domain Support option extends the valid domain IDs to 1–239 for both Standard and
McDATA Fabric Mode settings. However, all switches in the fabric must support 239 domain IDs.
System services
The System Services dialog provides a central location for you to enable or disable any of the external user
services such as SNMP, Secure Sockets Layer (SSL), Secure SHell (SSH), embedded switch management
application (McDATA Web Server or Element Manager), CLI, Network Time Protocol (NTP), and Common
Information Model (CIM). Select
Switch > Services to display the System Services dialog shown in
Figure 32 .
