If you select Port-Based Routing, enables port-based routing on 4 Gbps platform switches.
If you select Exchange-Based Routing, enables exchange-based routing for the fabric if all
switches are 8 Gbps or greater platforms running Fabric OS 6.4 or later. If these requirements
are not met, an error message displays.
If you select Device-Based Routing, enables device-based routing for the fabric if all switches in
the fabric are 8 Gbps or greater platforms running Fabric OS 7.1 or later. If these requirements
are not met, an error message displays.
NOTE
Either exchange-, port-, or device-based routing are enabled on all switches of selected fabric.
You cannot enable a mixed routing policy.
A warning message displays explaining that SCC and DCC policies will be created and activated
on the fabric. Click Yes to continue.
If configuration is successful, a confirmation message displays.
If FMS Mode was selected, each switch is checked for a CUP license. Any switches that do not
have a CUP license are listed, with a reminder that a CUP license is necessary to communicate
with the S/B FICON Management Server.
NOTE
FMS mode cannot be enabled on switches running Fabric OS 7.0 and later unless the switches
have an active CUP license.
DLS requires DLS support on the switch. Lossless DLS requires Lossless DLS support on the
switch.
Enabling DLS will enable IOD without lossless DLS on all other switches, enable DLS on
switches that support DLS, and disable DLS on all other switches.
DLS is only supported on the 40-port, 8 Gbps FC Switch, 80-port, 8 Gbps FC Switch, 512-port
Backbone Chassis, and 4-slot Backbone Chassis.
Enabling DLS may result in dropped frames when paths fail over. It is recommended that you
set the preferred IOD Delay Time to minimize frame drops.
To enable DLS, all switches in the fabric must be 8 Gbps or faster and running Fabric OS 6.4 or
later.
