For Fabric OS v7.0.0 and later, the supported routing policies are: • Port-Based-Routing - Port-based routing assigns a "static route," in which the path chosen for traffic never changes. • Exchanged-Based-Routing - Exchange-based routing policy is the default. Exchange-based routing policy always employs "dynamic path selection," in which the software defines a path based on current traffic conditions. • Device-Based-Routing - Device-Based Routing (DBR) is a read only option. If DBR is set in the switch, then the DBR radio button appears auto-selected and grayed out in Web Tools. Refer to the Fabric OS Administrator's Guide for more information. To optimize port-based routing, the DLS can be enabled to balance the load across the available output ports within a domain. Exchange-based routing requires the use of DLS; when this policy is in effect, you cannot disable the DLS feature. Use the Routing tab of the Switch Administration window to view and modify routing information. Figure 36 on page 158 displays the Routing tab. Web Tools Administrator's Guide 157 53-1002756-01

Routing overview
NOTE
To perform routing operations and Dynamic Load Sharing (DLS) configurations, the EGM license
must be installed on the switch; otherwise, access to these features is denied and an error message
displays.
For Fabric OS v7.0.0 and later, the supported routing policies are:
Port-Based-Routing — Port-based routing assigns a “static route,” in which the path chosen for
traffic never changes.
Exchanged-Based-Routing — Exchange-based routing policy is the default. Exchange-based
routing policy always employs “dynamic path selection,” in which the software defines a path
based on current traffic conditions.
Device-Based-Routing — Device-Based Routing (DBR) is a read only option. If DBR is set in the
switch, then the DBR radio button appears auto-selected and grayed out in Web Tools.
Refer to the
Fabric OS Administrator’s Guide
for more information.
To optimize port-based routing, the DLS can be enabled to balance the load across the available
output ports within a domain. Exchange-based routing
requires
the use of DLS; when this policy is
in effect, you cannot disable the DLS feature.
Use the
Routing
tab of the
Switch Administration
window to view and modify routing information.
Figure 36
on page 158 displays the
Routing
tab.
