4.7.2.8

Legacy Port Address Format

Legacy Address Format should be enabled only to permit interoperation with certain older non-FC-SW-2 switches. Enabling this setting under other circumstances will disable zoning that is defined by domain ID and port number. This setting is available only when the Interop Mode setting is disabled. Contact your authorized maintenance provider for assistance in using this feature. Refer to the QLogic Switch Interoperability Guide on the QLogic Web site for a complete discussion of configuring for operation with non-Qlogic switches.

Note: The Legacy Address Format setting must be the same on all switches in the fabric, otherwise the inter-switch links will not connect.

4.7.2.9

Timeout Values

The switch timeout values determine the timeout values for all ports on the switch. Table 4-5describes 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.
