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.

The switch timeout values determine the timeout values for all ports on the switch. 

 describes the switch timeout parameters. The timeout values must be 

the same for all switches in the fabric.

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

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.

R_A_TOV

Resource Allocation Timeout: Represents the maximum time a frame 
could be delayed in the Fabric and still be delivered. The default is 
10000 milliseconds.

E_D_TOV

Error Detect Timeout: Represents the maximum round trip time that 
an operation between two N_Ports could require. The default is 2000 
milliseconds.
