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

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.
After initiation, the first port from the trunk group that comes online is designated as the master
port. The other ports that come online on the trunk group are considered the slave ports. Adding or
removing a slave port does not cause frame drop; however, removing a slave port causes the loss
of frames in transit.
The restrictions for EX_Port frame trunking are the same as for E_Ports—all the ports must be
adjacent to each other using the clearly marked groups on the front of the product.
ATTENTION
This feature should be enabled only if the entire configuration is running Fabric OS v5.2.0 or later.
If router port cost is used with EX_Port trunking, the master port and slave ports share the router
port cost of the master port.
