Configuring link cost

When you configure link cost for the Core Switch 2/64, or for a SAN Director 2/128, or 4/256 SAN
Director configured for two logical switches, link cost is configured on a logical-switch basis. This means
that for each logical switch, you configure link cost individually.
For information regarding link cost, see the linkCost command in the HP StorageWorks Fabric OS 5.x
command reference guide.

Configuring the link cost for a port

1. Launch the Switch Admin module as described on
2. Click the Routing tab.
3. Perform the following, according to switch type:
• For Core Switch 2/64, SAN Director 2/128, and 4/256 SAN Director, click the slot number of
the logical switch under Link Cost in the navigation tree.
• For 4/8 SAN Switch, 4/16 SAN Switch, SAN Switch 2/8V, SAN Switch 2/16V, SAN Switch
2/32, 4Gb SAN Switch for HP p-Class BladeSystem, and SAN Switch 4/32, click Link Cost in the
navigation tree.
4. Double-click in the row in the Cost column that corresponds to the appropriate port.
5. Enter the link cost. For a 1 Gbit/sec ISL, the default cost is 1000.
For a 2 Gbit/sec or a 4 Gbit/sec ISL, the default cost is 500. Valid values for link cost are 1 through
9999. Setting the value to 0 sets the link cost to the default value for that port.
