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.

when used without operands, 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
