10. Enter the switchShow command to verify the EX_Port (or VEX_Port), edge fabric ID, and name
of the edge fabric switch (containing the E_Port or VE_Port) are correct.
11. Enter the fcrFabricShow command to view any edge fabric switch names and ensure links are
working as expected.
NOTE
The fcrFabricShow command displays the static IPv6 addresses for each FC router and each
edge fabric switch connected to the EX_Ports.

FC router port cost configuration
The FC router port cost is set automatically. This section provides information about the router port
cost and describes how you can modify the cost for a port if you want to change the default value.
FC routers optimize the usage of the router port links by directing traffic to the link with the
smallest router port cost. The FC router port cost is similar to the link cost setting available on
E_Ports, which allows you to customize traffic flow. The router port link cost values are either 1000
or 10,000. The router module chooses the router port path based on the lowest cost for each FID
connection. If multiple paths exist where one path costs less than the others, then the lowest cost
path is used. If exchange-based routing has not been disabled and multiple paths exist with the
same lowest cost, there will be load sharing over these paths.
The FC router port cost feature optimizes the usage of the router port links by directing the traffic to
a link with a smaller cost.
