About routing
For Fabric OS 5.2.0, 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 (Brocade 4100, 5000, and 48000 only).
Exchange-based routing policy is the default. Exchange-based routing policy always employs
“dynamic path selection,” in which the software chooses a path based on current traffic
conditions.
See the Fabric OS Administrator’s Guide for more information.
To optimize port-based routing, the dynamic load sharing feature (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.
To configure routing policies, you must use the command line interface (CLI). After the routing
policies are configured, you can use Web Tools to display the routing paths and configure routing
parameters, such as DLS, frame order delivery, and link cost.
