Routing overview
NOTE
To perform routing operations and Dynamic Load Sharing (DSL) 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 6.2.0, 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.
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 DSL 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 105 on page 212 shows the Routing tab.
