Introducing routing

For Fabric OS 5.x, the supported routing policies are:
• Port-based
• Device-based (4Gb SAN Switch for HP p-Class BladeSystem and SAN Switch 4/32 only)
• Exchanged-based (4Gb SAN Switch for HP p-Class BladeSystem, SAN Switch 4/32, and 4/256
SAN Director only)
For the 4Gb SAN Switch for HP p-Class BladeSystem, SAN Switch 4/32, and 4/256 SAN Director, 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. See the HP
StorageWorks Fabric OS 5.x administrator guide for more information.
To optimize port-based routing, the dynamic load sharing (DLS) feature 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 CLI. After the routing policies are configured, you can use
Advanced 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.
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 DLS radio buttons are not
displayed.
