Configuring a Static Route
7
Configuring a Static Route
A static route can be assigned only when the active routing policy is port-based. When device-based or
exchange-based routing is active, you cannot disable DLS and you cannot view and configure static
routes.
When you configure a static route for a SilkWorm 12000 director or for a SilkWorm 24000 or 48000
configured for two logical switches, it is on a logical-switch basis. This means that for each logical
switch, you must configure a static route individually.
To configure a static route
1. Launch the Switch Admin module as described on page 4-3.
2. Click the Routing tab.
3. This step is switch-specific:
For SilkWorm 12000, 24000, or 48000 directors, click a slot number under the Static Route
category in the navigation tree. Click Add.
For SilkWorm 200E, 3014, 3016, 3250, 3850, 3900, 4012, and 4100 switches, click the Static
Route category in the navigation tree. Click Add.
A new blank line appears in the window.
Note that when device-based or exchange-based routing policies are in effect, the Static Route
category does not display in the navigation tree.
4. Type the In Port number for the route.
5. Type the Destination Domain. The destination domain IDs match the outports in the cell.
6. Type the Out Port number for the route.
7. Click OK to add the static route.
8. Click Apply.
Enabling/Disabling Dynamic Load Sharing
The device-based and exchange-based routing policies depend on the Fabric OS dynamic load sharing
feature (DLS) for dynamic routing path selection. When these policies are in force, DLS is always
enabled and cannot be disabled.
When the port-based policy is in force, you can enable DLS to optimize routing. When DLS is enabled,
it shares traffic among multiple equivalent paths between switches. DLS recomputes load sharing either
when a switch boots up or each time an E_Port or Fx_Port goes online or offline. Enabling this feature
allows a path to be discovered automatically by the FSPF path-selection protocol.
For more information regarding DLS, refer to the dlsset command in the Fabric OS Command
Reference Manual.
When you enable or disable dynamic load sharing for the SilkWorm 12000 director or for a SilkWorm
24000 or 48000 configured for two logical switches, it is on a logical-switch basis. This means that for
each logical switch, you must enable or disable dynamic load sharing individually.
