For details about the use of any of the following commands, refer to the Fabric OS Command
Reference.
1. Enter the portDisable command to disable any port on which you want to set the router port
cost.
switch:admin> portdisable 7/10
2. Enable EX_Port or VEX_Port mode with the portCfgEXPort or portCfgVEXPort command.
switch:admin> portcfgexport 7/10 -a 1
3. Enter the fcrRouterPortCost command to display the router port cost for each EX_Port.
switch:admin> fcrrouterportcost
Port Cost
------------------------
7/3 1000
7/4 1000
7/9 1000
7/10 1000
7/13 1000
10/0 1000
You can also use the fcrRouteShow command to display the router port cost.
To display the router port cost for a single EX_Port, enter the fcrRouterPortCost command with
a port and slot number.
switch:admin> fcrrouterportcost 7/10
Port Cost
------------------------
7/10 1000
4. Enter the appropriate form of the fcrRouterPortCost command based on the task you want to
perform:
• To set the router port cost for a single EX_Port, enter the command with a port and slot
number and a specific cost:
switch:admin> fcrrouterportcost 7/10 10000
• To set the cost of the EX_Port back to the default, enter a cost value of 0:
switch:admin> fcrrouterportcost 7/10 0
5. Enter the portEnable command to enable the ports that you disabled in step 1.
switch:admin> portenable 7/10
EX_Port frame trunking configuration
You can configure EX_Ports to use frame-based trunking just as you do regular E_Ports. EX_Port
frame trunking support is designed to provide the best utilization and balance of frames
transmitted on each link between the FC router and the edge fabric. You should trunk all ports
connected to the same edge fabrics.
The FC router front domain has a higher node WWN—derived from the FC router—than that of the
edge fabric. Therefore, the FC router front domain initiates the trunking protocol on the EX_Port.
