Introducing Routing
For Fabric OS v5.0.x, the supported routing policies are:
port-based
device-based (SilkWorm 4012 and 4100 only)
exchanged-based (SilkWorm 4012, 4100, and 48000 only)
For the SilkWorm 4012, 4100, and 48000, the exchange-based routing policy is the default.
Using port-based routing, you can assign a static route, in which the path chosen for traffic never
changes. In contrast, device-based and exchange-based routing policies always employ dynamic path
selection, in which the software chooses a path based on current traffic conditions. Refer to 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. Device-based and exchange-based routing
require the use of DLS; when these policies are 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, configure static routes, and
configure routing parameters, such as DLS, frame order delivery, and link cost.
The Routing tab of the Switch Admin module displays routing information. Figure 7-1 on page 7-2
shows a Routing tab when the port-based routing policy is enabled. When a device-based or exchange-
based routing policy is enabled, the interface is different: the Static Route information and the Dynamic
Load Sharing radio buttons are not displayed.
