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.
Every IFL has a default cost. The default router port cost values are:
• 1000 for a legacy (v5.1 or XPath FCR) IFL
• 1000 for an EX_Port IFL
• 10,000 for a VEX_Port IFL
The FC router port cost settings are 0, 1000, or 10,000. If the cost is set to 0, the default cost will
be used for that IFL. The FC router port cost is persistent and is saved in the existing port
configuration file.
FC router port cost is passed to other routers in the same backbone. Link costs from the front
domain to the translate (xlate) domain remain at 10,000. You can use the lsDbShow command
from the edge fabric to display these link costs.
