Legacy Port Address Format
Legacy Address Format should be enabled only to permit interoperation with
certain older non-FC-SW-2, non-QLogic 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 FC-SW-2 Compliant setting is
disabled. Contact your authorized maintenance provider for assistance in using
this feature.
4.8.1.8
Timeout Values
The switch timeout values determine the timeout values for all ports on the switch.
Table 4-6 describes the switch timeout parameters. The timeout values must be
the same for all switches in the fabric.
Note: The Legacy Address Format setting must be the same on all
switches in the fabric, otherwise the inter-switch links will not connect.
Note: Timeout values can only be changed if the switch is offline.
