fcrRouterPortCost

Displays or sets an FC Router port cost.

Synopsis

fcrrouterportcost [[slot/]port] [cost]

Description

Use this command to set or display the cost of the FC router ports. You can set the cost of the link
to one of two fixed values: 1000 or 10000. The option 0 sets the cost of the link to the default
value based on link type (EX/VEX). The router module chooses the router port path based on the
minimum cost per fabric ID (FID) connection. If multiple paths exist with the same minimum cost,
the load is shared over these paths.

Every inter-fabric link (IFL) has a default cost. For an EX_Port IFL, the default cost is 1000. For a
VEX_Port, the default cost is 10000. If the cost is set to 0, the link cost defaults to 1000 for an
EX_Port and to 10000 for a VEX_Port.

If no operands are specified, this command displays the current link costs for all ports on the
switch.

Notes

Before setting the cost, ensure that admin is enabled for the EX_Port/VEX_Port with portCfgEXPort
or portCfgVEXPort. The cost can be set only on a disabled port.

The bandwidth of an inter-fabric link (IFL) is unrelated to its default cost. In other words, 1 Gbps, 2
Gbps, 4 Gbps, and 8 Gbps EX_Port IFLs have the same cost value of 1000 as their FC Router port.

The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may
be in place. Refer to chapter 1, “Using Fabric OS commands” and Appendix A, “Command
Availability”
for details.

Operands

This command has the following operands:

slot

For bladed systems only, specifies the slot number of the port whose cost is
to be displayed or changed, followed by a slash (/).

port

Specifies the number of the port whose cost is to be displayed or changed.
This value is relative to the slot for bladed systems. Use switchShow for a list
of valid ports. If a port is not specified, this command displays the costs of all
ports.

cost

Specifies the new cost of the link connected to the specified port. This
operand is optional; if omitted, this command displays the cost of the
specified port. The cost of the link can be changed only when the specified
port is disabled. Valid values for cost are 0, 1000 or 10000.

Examples
